Description

[0001] REEL SYSTEM FOR A VEHICLE [0002]

The present invention relates to an underwater reel provided for withdrawal during underwater movement of a vehicle, an air reel provided for subsequent air withdrawal to a target and to remain on the vehicle until then, and more particularly to a reel system for a carrier, particularly a guided missile, comprising an air reel and a continuous data line wound on both reels.

In the case of carriers that are launched with a mission, the carrier may need to remain connected to the guidance or control center for the entire mission duration, in order to be able to exchange image data, status data or navigation data. This can be accomplished by a data line provided for transmission of signals or a data line provided as a signal transmission line. Since the transmission bandwidth is high and at the same time the signal attenuation is low, such data lines are typically implemented as fiber optic cables. The data lines are wound onto a reel and connected to a spindle that carries a winding package. This data line is released from the reel during the movement of the carrier or during flight, so that the data link is maintained between the transmitting station of the control center or the receiving station and the moving carrier. The unwinding reel is usually placed on the carrier or within the carrier so that the data line to be loosened here can be kept in air or very quiet in water.

Such a reel system is known from DE 10 2004 024 858 A1. The carrier is a guided missile that uses the first part of its mission in water and the second part of its mission in the atmosphere. Thus, the reel system includes an underwater reel that is continuously connected to the guided missile during underwater movement and releases the data line. After the guided missile is released from the water, the underwater reel comes out with the buoy and the data line is released from the air reel remaining on the guided missile during the air flight. A buoy that forms a transition between an underwater data line and a data line on the water is dropped onto the surface of the water by hanging the parachute while the guided missile is flying to its target.

It is an object of the present invention to improve the reel system with respect to its operational capability.

This object is achieved by a reel system according to the features of claim 1, wherein the underwater reel according to the first aspect of the invention is attached to the air reel so as not to fall off.

The present invention is based on the idea that dropping an underwater reel on a buoy is a problem. Therefore, the data line must also be released as a missile during the descent of the buoy to compensate for the descent. This often results in the parachute or buoyant being entangled, thus causing the data lines to be twisted, thereby interrupting or even interrupting signal transmission. Once the buoy reaches the surface of the water, the data line loosened in the air descends above the buoy on the surface of the water, entangled on the buoy and also broken by twists or waves. The same or similar problems arise when attempting to hold the buoy under the surface of the water in order to make it more difficult to find it.

These problems are avoided by drop-resistant arrangement of the reel underwater on the air reel. Both reels remain on the carrier and buoys may not be needed. The data line is first unwound from the underwater reel and then unwound at the air reel where the line transition from the winding package of the underwater reel to the winding package of the air reel is advantageously implemented without a canister or buoy. Entanglement in buoys or separate underwater reels can be prevented.

The carrier is provided to be able to move in water and in the air, and moving here can mean flying and / or falling. The carrier may be a manned or unmanned aerial vehicle, advantageously provided with a drive, such as a rocket drive, for adjusting the vehicle in an underwater drive and / or a public drive or under water and also over water.

The air reel and underwater reel are preferably two reels, some distance apart from one another, each having at least one dedicated winding package. The winding packages are preferably designed such that the winding package of the air reel during the withdrawal is initially completely unwound, in particular completely, and then the unreeling of the reel system is carried out completely, It is solved.

The underwater reel is provided to be withdrawn during underwater movement of the carrier, in particular in the case of underwater flight driven by a rocket engine. Such provision may be made such that the unloading of the reel underwater, i.e., the withdrawal of the reel underwater, without any twisting of the data lines at that speed - and thus without any loss of data for normal signal transmission, Lt; RTI ID = 0.0 > data line. ≪ / RTI >

The air reel is provided for air withdrawal to the target. Which is also arranged to be fixedly attached to the components of the carrier during air withdrawal. If the carrier is a guided missile, the withdrawal is intended to be smooth and reliable and to be carried out up to a typical maximum speed for guided missiles, for example up to 250 m / s. The length of the data line here must be at least 5 km, in particular at least 20 km.

The underwater reel is attached to the air reel to be fixed against falling. This includes not providing discharge of underwater reels from the air reel in normal operation nor is it possible in no error operation. The underwater reel is thereby advantageously secured to the air reel so that it can be separated from the air reel only at the time of maintenance, especially by the tool. There is no release mechanism for automatic or manual release. Therefore, while the carrier is moving, especially the guided missile is flying, the underwater reel is moved to the target. That is: an underwater reel remains attached to the air reel when it is already unwound in flight, in particular even if at least half has already been released.

The underwater reel is advantageously attached at least partially behind the air reel. Such an arrangement is suitable because the data line is advantageously first unwound from the underwater reel while the carrier is performing its task in general and then released from the air reel. Direction is related to the direction of movement of the carrier or its structure so that the rear is positioned behind the carrier tip.

The reel may include at least a spindle and at least one winding package and optionally a housing that at least partially shields the winding package externally. The winding package includes a data line wound with a plurality of windings. The spindle may be an outer pulling spindle or an inner pulling spindle wherein the winding package is arranged radially outside the spindle so that the data line is wound on the spindle and in the case of the inner pulling spindle, . As a result, the data line here is initially wound as a winding package and the winding package is then inserted into an inner drawing spindle which can radially wrap the winding package and thus also perform the housing function. The inner drawing spindle and the outer drawing spindle are also referred to below as the inner spindle and the outer spindle in a simplified form.

The data lines advantageously include a data line body, such as a glass body, in particular a fiber optic conductor body. The data line body may be surrounded by a shielding body, for example another glass body having a different reflective index, so that there is a reflector plate on which data transfer radiation is maintained. In the case of electrical signals, metal shielding bodies are also possible. Moreover, the data line advantageously includes an outer protective sheath in the form of a cover having a plastic coating, a textile cover or a fibrous fabric. A stabilizing element, e. G., A stabilizing element, which improves the data line in terms of its own tear strength, may be disposed in the sheath.

The data line is a continuous line, i. E. The data line runs from the start of the reel underwater to the end of the air reel without passing to a reception station such as an amplifier or a different electronic component. This may, for example, have a splice between the winding packages between the two reels, that is, a junction where two previous separation parts of the data line are suitably joined together for signal transmission. Advantageously, however, the data lines are connected from one winding package to another winding package, in particular, so that the winding packages do not also engage, especially if the data line is implemented without the continuation from the beginning of the reel to the end of the air reel. .

The data line can be divided into an underwater line and an air line, wherein the underwater line is advantageously made thicker, i.e., thicker coated. This allows a larger draw resistance in the water to be taken into account. However, for example, a thicker underwater data line may be fed into the winder package of the air reel and may be used to rigidly separate the types of lines on the winder packages to, for example, It is not absolutely necessary. This is particularly advantageous if the data line is likely to be subjected to increased frictional or extraction resistance by unwinding in the air reel during underwater travel.

The two reels can, for example, form a system in which the spindles of the two reels are directly adjacent to each other and separated from each other only by, for example, a shoulder. A common one-piece spindle for both reels is also possible. In general, the water spindle is advantageously screwed or welded onto the spindle of the housing or air reel to ensure a tighter engagement.

Both reels can form an internal cavity and engine injection is induced through this cavity during the flight of the guided missile. In particular, in the case where an underwater spindle is implemented with an external spindle, the induction of engine injection through two spindles can be performed without transition. However, it is also possible that the spindle of the water reel is attached to the housing of the air reel. The underwater spindle can be an inner spindle or an outer spindle, depending on the structure of the underwater reel.

The underwater reel can protrude from the housing of the air reel and especially also from the housing of the guided missile. However, it is also possible for the housing of the air reel to at least partly wrap the reel underwater in the manner of a housing and thus protect it. The housing should not be made of one piece here, but the outer surface of the housing advantageously also forms the outer surface of the carrier or guided missile.

In one advantageous embodiment of the invention, the underwater reel is an internal withdrawal reel. The entanglement in the case of unloading an underwater reel in water, that is, in the case of withdrawing in water, is solved by the above embodiment. This aspect of the invention is based on the consideration that there is always a risk of multiple withdrawals, i.e., multiple coils being pulled out at the same time, in the case of a public withdrawal and also in the case of an underwater withdrawal, so that there is a set of open lines. This can easily be concluded by twisting the line. In the case of an external reel, the winding package is advantageously tapered in the backward direction, i.e., in the pull-out direction, so as to advantageously prevent a sharp winding edge to the rear in order to prevent multiple pull-outs. This is sufficient to be formed in the case of the air withdrawal because at higher speeds the unwinding of the data line will be accelerated outwards by a higher unwinding rate and the associated higher centrifugal forces and thus rising from the layers lying below it This is because the rising effect occurs. A number of air withdrawals are thereby eliminated. However, it has been found that, when unwrapped in water, the centrifugal effect is not sufficient to sufficiently raise the data lines from the winding layers below the data lines. Therefore, the data lines pulled backward are easily loosened to a very small radius, which causes the data lines to fall off laterally from the underlying layers. Moreover, small radii result in signal transmission being blocked or disturbed. These problems can be solved by internal withdrawal. The radially unwrapped data lines inside are more likely to rise radially from the underlying winding layers or outside the winding layers. Since the draw resistance is lower, the radius of the data line is tightest at the position where the data line is immediately inwardly separated from the winding package. Therefore, the data transfer operation in which no problem is caused by the internal withdrawal reel can be assured more easily.

Advantageously, the inner diameter of the output opening of the underwater reel is greater than the outer diameter of the outlet to the rear of the air reel. This, on the other hand, allows for a larger package volume of the winding package, so that in the case of a long line also a shorter underwater winding in the axial direction can be achieved. Moreover, the data lines can be separated more radially from the internal engine injection-depending on the structure of the carrier. Wherein the outlet to the rear of the air reel is identical to the opening supplied from the housing of the air reel while the data line is unwound from the air reel and back.

Other advantageous embodiments of the present invention provide that a line segment in the form of a transition segment from the winder package of the underwater reel to the winder package of the air reel is secured onto the winder package of the air reel. This fixation can be performed, for example, by gluing or fixing using a thread. In the case of bonding, a particularly stronger adhesive is useful, in which the adhesive which bonds the windings of the air reel to the other windings is useful. In this aspect of the invention, the following problems can be solved: in the case of underwater movement of the carrier, the air reel is also immersed in water, because the housing of the air reel has to be opened rearwardly to enable withdrawal. It is possible to provide the front openings in the housing of the air reel and to allow water to flow in from the front and back out through these front openings in order to prevent water from dipping from the rear to the front. Experiments have shown that water that is flowing backwardly back from the air reel is dragged on a line transition or transition segment. Therefore, especially the line transition is exposed to the flowing water, because the line transition must be raised from the air reel to feed the underwater reel. At this point, as a result of the flow of water, a greater force is applied to the line transition than to the other windings of the air reel. If the line transition is unintentionally raised from an air reel or even from an underwater reel, uncontrolled lines may quickly ball within the area of one or the other reel. This aggregation interferes with the unwinding of the data lines, so that the data lines are entangled. Now, when the line transition is attached to the air reel, the disappearance due to the flowing water can be solved. Advantageously, the adhesive is used for adhesion that is more easily lost at higher separation rates than at lower separation rates. In this case, it is easier to refer to the force by which the line transition can be separated from the windings of the base of the air reel.

It is further advantageous if the line transition from the winding package of the underwater reel to the winding package of the air reel is guided at least partially across the windings of the air reel winding package. As a result, the line transition provides a lower resistance to flowing water, so that the line transition can be more easily fixed. Where the transverse is at least 70 degrees, in particular orthogonal, with the windings of the winding package of the air reel. In practice, it may be possible to provide a relatively high resistance to the water flowing past the points where the line transition is still not traversing the windings. However, the firm fixation of the air reel on the line transition can be ensured over a relatively long distance by installing it transversely so that unintentional separation by the running water is avoided.

The withdrawal of the data line at the reel in the water is associated with high friction and thus is associated with the risk of entanglement of the data line. Even if the risk is reduced by the internal reel, it may be advantageous to use an external pull-out reel as an underwater reel. Suitable measures such as, for example, slow drawing, mutual adhesion of the windings of the winding package that are sufficiently matched to the pull-out rate, and / or conical spindle geometry that is tapered backward, prevent twisted or unwanted multiple draws, It may be easier to lift it from the windings of the base of the winding package.

Especially in the case of an underwater reel arranged as an external take-off reel, it is useful when the bottom of the windings of at least one spindle of an underwater reel is radially disposed within the lowest part of the windings of at least one spindle of the air reel. During the withdrawal of the air reel, the data line can be simply supplied radially and advantageously without contact with the outside of the water spindle so that damage to the data line can be prevented even in case of a very high withdrawal rate.

It is further advantageous if the diameter of the removal aid or induction means of the underwater reel is smaller than the diameter of the innermost layer of the at least one winding package of the air reel. This enables the data line of the underwater reel to be smoothly unwound from the air reel. It is particularly useful when the diameter of the radially outermost layer of at least one winding package of the underwater reel is smaller than the diameter of the innermost layer of at least one winding package of the air reel. In the above embodiments of the present invention, the induction means for directing the data line drawn from the underwater reel away from the windings of the base are not radially influenced beyond the outermost side of the winding package of the underwater reel without adversely affecting the air draw- It can protrude outward. The data lines may also be loosely loosened from the air reel in this case.

In order to prevent multiple withdrawals of underwater reels, i.e. simultaneous withdrawal of multiple windings of at least one winding package of an underwater reel, and furthermore to prevent twisting of the data lines, an underwater reel may, for example, It is advantageous to include induction means for lifting the data line being radially outwardly drawn from the lowest portion of the layer or winding. Although a similar effect can also be achieved by a conical diminution to the rear of the winding package, the embodiment has the disadvantage that the structure is longer in the axial direction. Therefore, by the induction means, the compact axial structure of the underwater reel can be combined with a reliable withdrawal in water.

As an induction means, such means are adapted to ensure that at least a portion of the data line is lifted far enough radially outward at the point where it is discharged from the winding package. One embodiment of the induction means is particularly simple in that it is a rear, radially projecting collar. This can for example be projected from the lowest part of the windings of at least one spindle, from other elements of the underwater reel, or directly from different units. The collar may be a rear tangential and circumferential shape that is directed radially outward and may be part of an underwater reel, for example. For example, a flange of one type of steel structure is possible. Advantageously, the induction means project radially beyond the outermost winding of at least one winding package of the underwater reel.

In order to prevent the air withdrawal from being interrupted in the air reel, the induction means is arranged radially in the lowest part of the windings of the at least one spindle of the air reel, that is to say at any point, radially beyond the lowest part of the windings of the air reel It is advantageous that it does not protrude. The axial position is independent of this. In this way it is ensured that even though the data line is drawn out from the lowest layer of the at least one winding package of the air reel, it is prevented from coming into contact with the inductive means during the air withdrawal and thus the signal transmission without interference through the data lines is maintained .

It is further advantageous if the induction means is inclined with respect to the winding package of the underwater reel in order to relieve the twist of the data lines during withdrawal in water. Advantageously, the slope is formed to form an angle greater than 120 DEG with respect to the lowermost portion of the windings of at least one spindle of the underwater reel, i. E. An angle greater than 30 DEG between the large radial direction and the slope. This inclination advantageously extends to the lowest part of the winding, in which case the small shoulder of the height of the two winding layers at the most is safe. The slope may advantageously be a radially rounded conical surface outwardly of the profile. The data lines can be dragged along the oblique and round segments without being bent or twisted by very small radii.

During underwater movement of the carrier, both reels are generally wet, since they are also submerged. Depending on the implementation of the data line, for example, in the case of a sheath wrapped with a textile or fibrous fabric, the sheath of the data line absorbs water. This can cause the thickness of the data line to increase and thus the winding package of the reel can cause a certain pressure build-up. This pressure can be a problem in the case of a transition or a transition segment of a data line from an underwater reel winding package to an air reel winding package, while the windings easily withstand such pressure.

It is advantageous that the transition of the data line from the winding package of the underwater reel to the winding package of the air reel is inserted into the laying groove to relieve the unwanted load on the data line. In this sensitive transition region or transition segment, the data lines can be protected and prevented from being twisted by the laying grooves. The grooved grooves can be machined into an aquatic reel, for example, in the front or rear flange of an aquatic reel. Advantageously, the grooved grooves can be located at the axial bounding surface of the underwater reel winding package, for example, adjacent to the flange. Advantageously, the laid grooves are guided to the radial top of the flange, for example the flange. It is more advantageous if the grooved grooves reach the lowest part of the winding so that the data line can be fed directly into the winding groove from the lowest layer.

It is more advantageous if the direction of the laying groove has a tangential component so that it is possible to smoothly transfer the direction in the winding direction of the tangential line of the data line at the lowest part of the winding. Advantageously, the orientation of the laying grooves is inclined by at most 30 [deg.], In particular by at most 15 [deg.], With respect to the orientation of the lowest part of the winding at the position at which the laying grooves reach the lowest part of the winding. The grooved grooves can advantageously be embodied here at least in essentially straight or curved lines.

Another advantageous embodiment of the present invention provides for an underwater reel to be disposed with respect to the air reel so that the data line is drawn through the spindle when it is drawn radially in the spindle embodied as the outer spindle of the reel underwater and from the air reel . Therefore, the underwater reel forms an internal opening through which data lines are supplied. Such an arrangement has the advantage that the winding package of the underwater reel is relatively large in radial direction and therefore can be implemented compactly in the axial direction and furthermore the radial distance of the data line to be unwound from the engine injection can be made relatively large.

It is further advantageous if at least one winding package of the underwater reel is partially disposed behind at least one winding package of the air reel. Due to the axial overlap of the two winding packages, an axially compact arrangement in the system can be achieved so that the carrier or guided missile can be manufactured compact in the axial direction.

Advantageously, the lowermost portion of the windings of at least one spindle of the underwater reel lies radially outside the lowermost portion of the windings of the at least one spindle of the air reel, and the circumference of the lowermost portion of the windings of the reel underwater is therefore the lowest It is bigger than the circle of wealth. The lowest part of the windings of the reel underwater may here or in part be placed behind the lowest part of the windings of the air reel.

The compact, mechanically stable construction of the reel system can be achieved when at least one spindle of the underwater reel is attached to the housing of the air reel. A retaining force flow flows between the reels and thus through the housing. There may be a space between the at least one spindle of the air reel and the underwater reel, and the data line that is drawn out of the air reel through this space is passed. Such a drawout space separates the two spindles of the two reels.

Likewise, the compact construction is beneficial when at least one spindle of the water reel forms the housing segment of the air reel. The housing segment is advantageously conically tapered rearwardly so that the inner diameter of the housing is thereby reduced inwardly and the spindle thus forms part of the housing which narrows downwardly. The spindle may be embodied by a plurality of layers such that the material of the housing is different from the material of the lowest portion of the windings of the spindle of the reel in the water.

Advantageously, the transition segment of the data line from the at least one winding package of the aquatic reel to the at least one winding package of the air reel is initially led backward from the reel underwater and then radially through at least one spindle of the reel underwater It is led forward. The arrangement is also advantageously retained even if the segment of the data line is not yet untwisted, even in an underwater reel, not to mention an air reel.

The large winding package volume at the reel underwater and thus the long data line is achieved when the lowermost portion of the windings of at least one spindle of the underwater reel is placed radially further out than at least the inner portions of the at least one winding package of the air reel .

During the withdrawal of the data line from the underwater reel and air reel, the data line may take a high load due to the high withdrawal rate. Particularly at the transition of the withdrawal of air to the reel from the underwater reel, the data lines drawn constitute waves, which cause an increase in load. In order to keep such waves small, a data line is implemented in the form of a groove in which a data line is, for example, later grooved in the transition region or transition segment of the air reel from the winding package of the air reel to the winding package It is advantageous to be guided in a recess which can be formed. The recess or grooved groove may be disposed on the rearward end of the underwater reel, for example, as a flange, or in a rearward guiding means of the underwater reel which may be embodied as a radial elevation generally on the lowest portion of the winding . The laid grooves are advantageously arranged on the side of the induction means leading to the radial top of the induction means and towards the winding package.

It is further advantageous if the laying grooves include a first groove segment facing the winding package and a second facing groove segment. Both segments can be placed in the induction means. The data lines advantageously lie within both segments.

Particularly high withdrawal loading of the data lines can be prevented if the laying grooves pass through the guiding means as in a valley at the rear part of the underwater reel in the region of the maximum radial extent of the guiding means. The data line drawn out from the laying groove does not form a large wave as in the case of no laying groove.

To keep the wave small, the grooved grooves must be deeply cut into the guide means. It is advantageous if the radial elevation of the valley bottom projects above the lowest part of the winding by at most 30% of the rise of the induction means at the lowest part of the windings of the at least one spindle of the water reel. The valley bottom, however, is also radially deeper than the lowest part of the spindle or the lowest part of the windings of the reel underwater.

During withdrawal in the underwater reel, the data line can be dragged across the edge of the inductive means. In order to keep the loads of the data line small, the edge must therefore proceed as smoothly as possible along the circumference. This advantageously results in a maximum of 20% of the elevation of the guiding means on the lowest part of the spindle of the reel underwater by the grooved grooves, when viewed from the rear of the outer edge-guiding means of the circularly profiling means, Can be achieved when radially notching up to 5 mm, in particular up to 2 mm.

Discontinuities in the course of the data line, such as the twist of the data line, can result in a wave during outcoupling and thus an increase in fetch loading of the data line. In order to keep the loading small, the base of the grooved groove on its rear end is curved radially in such a way that the data line is guided in the grooved grooves without any radial kinks and without any radial kinks from the grooved grooves Is advantageous.

When the drawing point of the data line passes through the rear guiding means and enters radially inward behind the guiding means, the data line is minutely deflected in the tangential direction by the change of the direction of the drawing point. In order to prevent the data line from colliding with the edge of the rear region of the laying groove, it is advantageous that the groove segment which is directed to the rear of the laying groove goes out axially rearward in the drawing direction of the tangent of the data line.

The groove segment facing the winding package of the reel underwater is at an angle of at least 75 ° with respect to the axial direction of the reel system and, as far as practically possible, extends over the largest part of its entire length, in particular the entire length of the grooved segment or the front region of the grooved groove The smooth course of the data line can be achieved in relation to the smooth outer edge of the inductive means.

In the case of embodiments in which the rear end of the air reel lies axially before the rear end of the reel underwater, it is advantageous if the data line is wound on an intermediate reel between the underwater reel and the air reel. The intermediate reel may include an intermediate winding comprised of only one layer.

In order not to interfere with withdrawal from the error reel, the intermediate winding on the intermediate reel is advantageously arranged radially completely within the lowest part of the windings of the at least one spindle of the air reel. Advantageously, the intermediate reel is provided with a laying groove on the front flange, in which the data lines lie.

Moreover, the present invention is directed to a guided missile having a carrier, in particular a rocket engine, wherein the reel system is arranged rearwards, in particular as described above. It is proposed that the underwater reel of the reel system provided for withdrawing the data line during underwater movement of the carrier is attached to the rear so as to be fixed against falling. Advantageously, the reel system is disposed behind the carrier and especially around the engine ejection chamber. The underwater reel advantageously comprises at least one spindle and at least one winding package.

Moreover, the present invention is directed to a method of maintaining a data link between a carrier moving by a data line, in particular a guided missile and a control center, in particular a launch station, in which the data line is moved And the carrier enters the air through the surface of the water and is withdrawn from the air reel during movement on the water. The control center may be in a building or carrier, for example, in a submarine.

It is proposed that the underwater reel is preferably held fixedly attached to the air reel during in-water movement and water movement to the target of the carrier. Exporting an interface, e.g., a buoy, may be excluded, thereby preventing entanglement of the data lines.

Air withdrawal advantageously occurs, for example, after the flight phase, until the carrier reaches a predefined target. Advantageously, the segment of the underwater reel is still drawn into the air.

Moreover, the present invention is directed to a method for winding a reel system having a data carrier that is implemented to maintain a data carrier between a moving carrier, in particular an in-flight guided missile and a control center, It is wound initially on the spindle of the air reel and then on the spindle of the reel underwater reel.

It is advantageous if the data lines are wound in a single piece on an underwater reel and an air reel to avoid breakage of the data line during unrolling. For this purpose, both reels must be wound into a continuous data line. To achieve this, it is proposed that the spindle of an underwater reel in accordance with the present invention is held in an available position between the spindle of the underwater reel and the spindle of the air reel in order to expel the data line during withdrawal from the air reel.

Advantageously, the spindle of the aquired reel is held in its winding position by an auxiliary retainer during winding, where the auxiliary retainer is removed after winding and the spindle is then attached to the air reel to be ready for operation. The spindle may be attached directly or advantageously indirectly, in particular by the housing of the carrier.

To attach an underwater reel to an air reel, both reels are advantageously held stationary relative to each other during the attachment process. A third element is attached to the underwater reel and the air reel for attachment to attach them together. Advantageously, said third element is a housing of a carrier. Advantageously, the air reel is attached directly to the housing of the carrier. However, it is also possible to advantageously attach the air reel to the housing of the carrier by one or more additional elements.

The guided missile is connected to the control center 6, which is a submarine by the data line in the present exemplary embodiment. The data line 4 is a line having an optical fiber core covered by a plastic sheath for transmitting optical signals.

The guided missile was launched from a torpedo tube of submarines forming a firing station 8 for guided missiles. The guided missiles traveled across the surface of the water 10, for example at a depth of 400 m, over a distance 12 along the mission. After traversing the underwater distance 12, the guided missile changes its direction of movement and passes through the surface of the water 10 and now continues its movement towards the target 14 on the surface of the water 10. [ The target may, for example, be at a distance of 25 km from the control center 6, and most of the distance is covered by the carrier 2 in the atmosphere.

The data line 4 is attached to an interface 16 in the submarine and is connected to a control unit 18 of the control center 6 by another data link for signaling purposes. The control unit 18 controls the flight of the carrier 2 in both water and water and processes the image data created by the seeker head of the carrier 2, Lt; RTI ID = 0.0 > 20 < / RTI > The control unit 18 is connected to a control unit 22 which is arranged in the carrier 2 via a data line 4 for signaling purposes. The control unit 22 controls the flight of the carrier 2 to a rudder 24 where the control commands are transmitted by the data line 4 from the control center 6 to the control unit 22 . In turn, the data of the detector head 20 is transferred to the control center 6 by the data line 4, and the control center 6 creates control commands from this data.

The interface 16 is not shown to enable the displacement of the control center 6 relative to the surrounding water to be compensated without the data line 4 being pulled through the water, Includes a reel. However, the greatest portion of the data line 4 is provided by the reel system 26, which is disposed behind the carrier 2 and is described in detail in Fig.

Figure 2 shows the rear section of the reel system 26 of the carrier 2 in Figure 1 as a longitudinal section. In Figure 2, the reel system is provided with a reference character 26a. In the following exemplary embodiments, similar elements are characterized by the same reference numerals, but are not limited to, for example, examples with different reference characters when the elements are minutely different in, for example, dimensions, position and / Lt; / RTI > embodiment. Reference numerals alone, without reference characters, refer to corresponding elements in all the exemplary embodiments.

The reel system 26a includes an air reel 28a and an aquatic reel 30a that is disposed entirely behind the air reel 28a in this exemplary embodiment. While the air reel 28a is embodied as an external withdrawal reel, the underwater reel 30a is embodied as an internal withdrawal reel.

The data line 4 is wound both on the air reel 28a and also on the reel 30a and continues without interruption, especially without splicing. The air reel 28a includes a spindle 32a, and the data line 4 is wound on this spindle. Although the underwater reel 30 is also provided with a spindle 34a which in the exemplary embodiment is a layer of the winding package 36a-data line 4 of the reel 30a from the outside, Which is a spindle which radially surrounds the inner spindle formed by the windings. In contrast, the spindle 32a of the air reel 28a is radially disposed within the winding package 38a of the air reel 28a.

The data line 4 is divided into three segments: the winding package 36a forms an underwater segment 40 of the data line 4, starting at the interface 16 of the control center 6, Lt; RTI ID = 0.0 > 36a < / RTI > to form such an underwater segment. The transition segment 42a connects the winding package 36a to the winding package 38a of the air reel 28a. The air segment 44 of the data line 4 forms a winding package 38a and leads to the control unit 22. [ Transition segment 42a may also form some windings of air reel 28a. A single, continuous fiber optic cable that is guided through three segments 40, 42a, 44 without being attached to all three segments 40, 42a, 44 is traversed. Only the cus of the data line 4 is different in the segments 40, 42a, 44. [ The sheath is implemented thicker in the segments 40, 42a than in the air segment 44. [ As a result, the data line 4 becomes more tear-resistant in the two rear segments 40, 42a than in the air segment 44. [ However, the air segment 44 is relatively slim and light in its construction, and as a result can be drawn out more quickly, which is particularly advantageous for air withdrawal.

While the guided missile travels through the water at a specific rate during the underwater movement and releases the reel 30a at the corresponding rate, the withdrawal of the data line 4, after breaking the surface of the water 10 It accelerates considerably because the guided missile reaches a speed of up to 250 m / s while flying to its own target (14).

During the entire flight, an underwater reel 30a, with its own spindle 34a-up to where the data line 4 is unwound-remains on the carrier 2, both above and below water. For this purpose, the spindle 34a is fixedly connected to the other components of the carrier 2, in this exemplary embodiment, to the outer housing 48a of the guided missile 2, 28a. ≪ / RTI > The spindle 34 is screwed into the housing 48a and is therefore not releasable during the flight of the guided missile. This can be separated from the rest of the carrier 2 after removal of the winding package 36a using only a tool, but the tool is not provided in normal operation. Alternatively, it is conceivable that the underwater reel 30a or its own spindle 34 is welded to the carrier 2. [

In order to prevent unwanted pull-outs and to facilitate lifting the data lines 4 radially and drawing them from the windings or layers of the base of the winding package 36a, the underwater reel 30 or its spindle The induction means 50a is formed in the form of a flange connected to the lowest portion of the winding 52a of the spindle 34a by one piece. In the case of underwater withdrawal, the data line 4 is dragged over the rounded edge 54a of the flange 50a and consequently raised radially inward at an arbitrary angle from the underlying winding layer. In this case, the induction means 50a is embodied here as a radially inward formation so that the radial innermost layer of the data line 4 is pulled inwardly for some time during withdrawal, Of the innermost winding layer of the winding package (36a). The radius of the guiding means 50a at the narrowest point, that is at the edge 54a, is such that the data line 4 released from the air reel 28 is not in contact with the edge 54a, Should be greater than. A radius of at least 1.1 times the outer radius of the outlet 60a is particularly suitable.

Moreover, the induction means 50a has the effect that the winding package 36a need not be radially thinner toward the rear to prevent multiple draws. The induction means 50a defines a winding package 36a on the rear side, which prevents unwanted multiple draw-outs by itself. For this purpose, the winding package 36a is at least essentially not narrowed and is adjacent to the inductive means 50a.

When immersed in water, the internal space 56 in the housing 48a or around the air reel 28a is submerged into the water flowing into the interior space 56 through the openings 58. This water flows backward and exits from the housing 4a of the air reel 28a through the outlet 60a. The flowing water drains the windings of the winding package 38a of the air reel 28a. However, since the data lines 4 are glued within the winding packages 36a, 38a, the individual windings of the data line 4 are consequently glued together so that the winding packages 36a, 38a are stable. The adhesive is selected so that the data line 4 is not twisted much enough to jeopardize data transmission in the case of a draw. On the other hand, the adhesive is very strong so that the corresponding winding packages 36a, 38a are also kept sufficiently tucked together in the water and that many draws do not occur as a result of loose windings.

However, the transition segment 42a is fed a short distance through the air, so that flowing water pulls the segment 42a more strongly. The portion of the transition segment 42a is more strongly pressed against the air reel 28a than the windings 62 are bonded together to prevent the transition segment 42a of the data line 4 from being pulled with moving water. Gt; 62 < / RTI > To this end, an adhesive is used which is capable of separating the bonded data lines 4 at a lower force than at a slower separation rate in the case of a fast separation rate. The adhesive may be silicon, and silicon is added between the windings 62 and the transition segment 42a.

Moreover, the transition segment 42a is fed transversely, that is, perpendicular to the winding direction of the windings 62, to achieve a distance as far as possible. Although the water pushed through the inner space 56 is pulling the rear portion of the transition segment 42a very strongly, the transversely-oriented portion of the transition segment 42a is pushed by the water that is pushed into the data line 4, And still remain fixedly coupled to the windings 62 so as not to separate in an undesired manner from the windings 62 of the base 28a of the reel 28a.

The transition segment 42a extends somewhat into the winding package 38a of the air reel 28a and forms part of the upper layer of windings of the air reel 28a. This enables the air reel 28a to be drawn as far as the transition segment 42a reaches below water without the data line 4 being adversely affected. What has been mentioned about the transition segment 42a is also applied to the transition segments 42b and 42c.

The air reel 28a is an external reel that includes a plurality of winding layers extending parallel to the lowermost portion of the spindle or the lowermost portion of the winding 64a. The plurality of winding layers form a winding package 38a, which is wound backwardly to prevent unwanted withdrawal of the rear windings.

When the carrier 2 is moving, the carrier is initially fired from the launch station, where the data line is essentially unwound from the underwater reel 30a but is also loosened from the reel of the interface 16 to some extent. The unwinding is performed here by the traction force applied to the data line 4 by the carrier 2 moving so that the data line is released by itself.

The length of the underwater segment 40 of the data line 4 is dimensioned such that the specified distance 12 under water is longer or shorter than the length of the underwater segment 40 by +/- 30 m. When the carrier 2 escapes from the water, the underwater reel is therefore at least essentially completely unwound. If there is still a data line 4 on the reel 30a at the time of the escape, it is first unwound on the water such that it does not exceed 30m, where the carrier 2 is withdrawn or unloaded from underwater reel 30a It is not very fast enough to be a problem. On the other hand, if the movement in the water is not yet completed, if the underwater reel 30a is unwound, the transition segment 42a or transition data line 2 to 3 meters long can still be unwound from the air reel 28a, Transition segments or transition data lines withstand high mechanical loads of underwater withdrawal.

Figure 3 shows another reel system 26b with an air reel 28b and an underwater reel 30b. The description of the following exemplary embodiments is essentially limited to differences with the exemplary embodiment of FIG. 2, and reference is made to the exemplary embodiment of FIG. 2 for the same retained features and functions. Elements that remain essentially the same are numbered theoretically with the same reference characters, and the features not mentioned are taken in the following illustrative embodiments without being recounted.

The air reel 28b is essentially the same as the air reel 28a from FIG. 2, whereas the water reel 30b is an external withdrawal reel. Which is essentially located outside the housing 48b, which can be manufactured in the same manner as in the exemplary embodiment of Fig. 2 for the openings 58. [ Although the winding package 36b of the underwater reel 30b is wound into multiple layers as in the winding package 36a of the underwater reel 30a, in the exemplary embodiment in FIG. 3, the data line 4 It is wound from inside to outside to loosen inward.

The spindle 34b of the underwater reel 30b is directly connected to the spindle 32b of the air reel 28b or both spindles 32b and 34b are connected to at least the lowest portions of their windings 64b, Are connected to one piece so that they are in one piece. The spindles 32b, 34b may be constructed of metal or plastics for special applications.

The two reels 28b and 30b are embodied as hollow reels and are provided with a tubular cavity 68 (Fig. 4B) so that the rocket engine of the guided missile, or the rocket engine of the guided missile, ). The engine injection also passes through the reels 28b and 30b.

In order to prevent undesired multiple withdrawals during underwater withdrawal, the underwater reel 30b is implemented with its inwardly directed means 50b. Which projects radially beyond the outermost layer of the winding package 36b over the entire circumference, as shown in Fig. 3, which illustrates the winding package 36b with dashed lines. During withdrawal, the data line 4 traverses the outer rounded edge 54b of the inductive means 50b such that the radially projecting edge 54b lifts the data line 4 from which it is unwinding from the underlying layer Dragged. The friction of the data line 4 during withdrawal is kept low in this manner so that the data line 4 is not kinked and signal transmission can be maintained unimpeded. Furthermore, the induction means 50b allows the winding package 36b to also be limited to the rearward direction so that the rear windings can not leave the winding package 36b and the data lines 4 are not entangled during unwanted multiple draws.

The entire winding package 36b of the underwater reel 30b is radially disposed within the winding package 38b of the air reel 28b to ensure unobstructed air withdrawal. The radially outermost layer of winding package 36b is therefore radially disposed within the radially innermost layer of winding package 38b. Furthermore, the induction means 50b is also dimensioned within its radial extent so as to project radially no less than the lowermost portion of the windings 64b of the air reel 28b. In this way it is ensured that the data line 4 drawn out of the air reel 28b does not come into contact with the underwater reel 30b and in particular its inductive means 50b. The outer diameter of the inductive means 50b of d = (0.8 + - 0.1) D has been successfully demonstrated in the case of the draw where the data line 4 does not contact the air reel 28b, The diameter of the lowest portion of the winding 64b.

It is also possible, however, that the induction means 50b project somewhat radially beyond the lowest portion of the winding 64, but remain at least 3 mm radially overall within the outer circumference of the outlet 60b. This is because the data line 4 is pulled out by the centrifugal forces due to the rotational withdrawal and the resultant during the air withdrawal and is stopped on the round inner edge of the housing 48 in the region of the outlet 60b. If the inner edge is sufficiently far from the lowermost portion of the winding 64b that the edge 54b or the inducing means 50b project somewhat radially beyond the lowermost portion of the winding 64b, (30b).

The spindle 34b of the underwater reel 30b is shown in a perspective view in Fig. Figure 5 shows the spindle 34b in side view. The lowest portion of the winding 52b is disposed between the two flanges 50b and 66b such that the winding package 36b is held between the front flange 66b and the rear guide means 50b embodied as a flange. The windings of the winding package 36b, which are not directly drawn out, therefore are caught between the two flanges 50b, 66b - even if it exits in the axial direction. Therefore, it is not possible for a falling or a large number to be pulled out from the winding package 36b.

As can be seen from Fig. 5, the side of the flange facing the winding package 36b is tilted radially by angle?. The angle reduces the bending radius of the data line pulled into the edge 54b so that even in the case of the highly constrained data line 4 the data transfer occurs unimpeded. The higher the maximum velocity of the carrier in the water, the greater the angle? On the other hand, if the angle? Is greater than the predetermined axial structural length of the underwater reel 30b, the installation space for the winding package 36b is eliminated, so that different spindles or reels are available for underwater movement at different speeds.

In this regard, the present invention is generally directed to a system of at least two waterborne vessels having different structure-related maximum velocities in water. Each of the ships is provided with a reel system according to the present invention, wherein the inclination angle &thetas; with respect to the radial direction of the rearward guiding means 50b is greater than the inclination angle in the case of selection having a greater maximum speed than in the case of a ship having a lower maximum speed It is bigger.

In order to achieve high position stability, the winding package 36b is directly led forwardly to the rear wall of the flange 66b and thus to the flange wall. The rear edge of the front flange 66b can be passed vertically to the lowest portion of the winding 52b, resulting in a larger winding space. The data line 4 in this region is led from the radially innermost layer of the winding package 36b to the air reel 28b to the outside air reel 28b where the data line 4 is therefore wound on the winding package 36b and the flange 66b, . If the winding package 36b is now swollen as a result of wetting it will apply pressure to the rear wall of the flange 66b and thus crimping the data line 4 between the winding package 36b and the flange 66b )do. This may cause the data lines 4 to be twisted, especially in the radially inner region.

In order to prevent this, the flange 66b which limits the winding package 36b in front is designed to have the laying groove 70b. Which is machined as a recess in the rearward facing surface of the flange 66b and extends radially inwardly to the lowest portion of the winding 52b. The grooved grooves 70b are provided with tangential components in their own orientations so that the data lines 4 can be guided radially outwardly from the lowermost portion of the windings 52b through the grooved grooves 70b radially outwardly do. The laid grooves 70b are thus formed in the vicinity of the ends of the data lines 4 that are opened and curved along curves 72 with their radially outwardly facing surfaces immediately before the bottoms of the turns 52b Determine the curvature.

During withdrawal from underwater reel 30b, the last layer of winding package 36b is therefore withdrawn forward from the back and the piece of data line 4 is then directly initiated to withdraw the surface-adhered transition segment 42a Is pulled out from the grooved groove 70b.

The grooved groove 70b has a depth at least 0.8 times the diameter of the data line 4 in the transition segment 42a. The underwater segment 40 of the data line passing transversely to the grooved grooves 70b in the winding package 36b is therefore not twisted by the edges of the grooved grooves 70b and the width of the grooved grooves 70b must be kept small do. This should especially not be greater than 5 times the diameter of the data line 4 in the transition segment 42a, especially only up to 2 times. The ratio of the width of the grooves between 1 and 2, in particular between 1.2 and 1.6, to the diameter of the data lines is particularly advantageous.

Advantageously, underwater reels 30a of reel system 26a are also provided with laying grooves. This can be accurately implemented as in the grooved grooves 70b in Fig. 4 where the grooved grooves are located within the front flange of the spindle 34a and within the housing 48a, which will also be useful in the case of the exemplary embodiment of Fig. 2 Can be machined. In each case the laid grooves will be machined into components directly in contact with the winding package 36a and define the winding package 36a at the front.

Another exemplary embodiment of reel system 26c is shown in Fig. The reel system 26c again has an air reel 28c and an underwater reel 30c. The air reel 28c can be implemented in the same manner as the previous air reel 28a, 28b, up to the housing 48c. The underwater reel 30c is embodied as an external reel, but is disposed radially outside the lowest portion of the windings 64c of the air reel 28c. The lowest portion of the winding 52c and thus also the entire winding package 36c of the underwater reel 30c is thereby radially disposed outside the lowest portion of the winding 64c of the air reel 28c.

The data line 4 being released during withdrawal is supplied radially inward through the spindle 34c of the underwater reel 30c during withdrawal from the air reel 28c and contacts the spindle 34c during the internal withdrawal, The contact occurs on the side of the spindle 34c facing away from the winding package 36c.

The spindle 34c of the underwater reel 30c forms part of the housing 48c of the air reel 28c and the data line 4 released during the draw is guided through the outlet 60c along the inner surface thereof. The housing 48c is an element that radially outwardly surrounds the air reel 28c and completely surrounds the air reel in a radially outward direction. The spindle 34c of the underwater reel 30c surrounds the air reel 28c at its rear end and forms a part of the housing 48c. By combining the inner surface of the spindle with the inner surface of the housing, a particularly compact structure can be achieved. Moreover, the parts and materials and hence the weight are saved.

The spindle 34c is attached directly to the housing body of the housing 48c wherein the housing 48c is further radially guided over the reel 30c for water for self protection against external influences. The housing 48c is thus split into two parallel conducting segments in the region of the spindle 34c and these two radially overlap each other: the inner parallel portion is in the region of the opening 60c and the spindle 34c, As shown in Fig. The outer region forms a radial cover for the housing of the carrier and the underwater reel 30c for external protection.

The lowest portion of the windings 52c of the underwater reel 30c is positioned so that the diameter of the winder package 36c of the underwater reel 30c is greater than at least the inner windings of the winder package 38c of the air reel 28c, Radially along the entirety of the outside of the lowest portion of winding 64c of coil 28c. In this way, a large winding volume and hence a long length of the data line 4 can be introduced into a relatively small axial installation space. Moreover, the data line 4 moving out of the outlet 74 can be maintained radially away from the cavity 68c where the engine injection is fed to propel the carrier 2 while the carrier 2 is moving.

The underwater reel 30c is disposed relative to the outlet 60c so that its spindle 34c lies axially in the region of the narrowest point of the outlet 60c. In this way, the overall structure is particularly compact. In particular, the inner surface of the spindle forms the outer wall of the outlet 60c in its narrowest section.

The underwater reel 30c is partially axially disposed behind the air reel 28c and at least some areas of the underwater reel 30c are also axially disposed behind the air reel 28c. Ideally, the underwater reel 30c should be placed axially completely behind the air reel 28c, or alternatively the water reel 30c may be positioned so that the air reel 28c is farther back axially than the water reel 30c It is also possible to allow the air reel 28 to be terminated at the rear thereof before it.

Figure 7 shows the rear portion of the carrier 2, wherein the illustration of the rudder 24 in Figure 1 has been omitted for clarity. The rear portion of the housing 48c in which the water reel 30c is disposed can be identified. And its outlet 74 forms a radially outermost region in the housing 48c at the rear of the carrier 2. [ It will be appreciated from Figure 7 that the large radius of the underwater reel 30c is capable of long data lines 4 on the reel 30c underwater compared to the relatively flat structure of the reel package 36c of the reel 30c .

The rear of the spindle 34c of the underwater reel 30c and the spindle 76 of the intermediate reel 78 can be seen in the outlet 74 of Figure 7 and the intermediate reel 78 can be seen in the underwater reel 30c Radially. The winding package 36c and the intermediate winding 80 of the underwater reel 30c, shown by dashed lines in Fig. 6, are not shown. The cavity 68c, which lies radially in the intermediate reel 78, forms a passage for engine injection of the carrier during flight of the carrier.

8 shows a perspective view of the carrier 2 in a direction from behind to the front in the direction of flight of the carrier 2, wherein the rudder 24 is omitted from the drawing again. The winding package 38c of the air reel 28c in front of the spindle 76 of the housing 48c, the spindle 34c of the water reel 30c, the outlet 60c, the intermediate reel 78, A cavity 68 with engine injection can be shown - from outside to inside. Also shown is the transition segment 42c of the data line 4 in the transition region from the underwater reel 30c to the intermediate reel 78. [

The spindle 34c of the underwater reel 30c is shown in side perspective in Fig. 9 without housing 48c. A front flange 66c defining only the marked winding package 36c of the underwater reel 30c at the lowest portion of the winding 52c and a rear guide means 50c defining the winding package 36c at the rear are shown . As described with respect to Fig. 5, the inductive means 50c extends cone angle a back conically from its side towards the winding package 36c.

The laid grooves 70c are formed in the conical surface including a front groove segment 82 and a rear groove segment 84. [ The front groove segment 82 is cut into a conical, forwardly facing ramp of the inductive means 50c while the rear groove segment 84 is machined into the rearward facing surface of the inductive means 50c. In contrast to the exemplary embodiments of FIGS. 2-5, in this exemplary embodiment the laying grooves 70c are disposed at the rear end of the winding package 36c in the inductive means 50c.

The data line 4 extends from the lowermost portion of the winding 52c through the front groove segment 82 of the laying groove 70c and into the rear groove segment 84 of the laying groove 70c, Which is then delivered from the winding and then straight to the intermediate winding 80. The data line is not guided here particularly radially outwardly by the inductive means 50c and passes through the inductive means 50c whereby the wave formation of this data line 4 during the withdrawal of the data line 4 and Thus, any impact on the data line 4 and its loading can be kept low during withdrawal. In FIG. 9, it is indicated how the data line of FIG. 4 is pulled in a straight line from the forward groove segment 82 of the laying groove 70c during the draw on the water.

The incision of the front groove segments 82 in the induction means 50c can be particularly well recognized in FIG. The valley bottom 86 is cut deep into the induction means 50c and protrudes slightly beyond the radial extent or radius R ₁ of the lowermost portion of the winding 52c only in the region of the maximum radial extent of the induction means. The maximum radial elevation of the valley floor 86 or its maximum radius R ₂ is less than 50% of the rise of the induction means 50c above the lowest portion of the winding 52c, 3, wherein the positive radii R ₁ , R ₂ are measured from the axis of symmetry of the reel system 26c or of the spindle 34c. In this way, the extension of the data line 4, which may occur by overcoming the inductive means 50c, can be kept small, thereby reducing wave formation during drawing.

Figure 11 shows the section of the spindle 24c of the underwater reel 30c from behind to the inductive means 50c. The valley floor 86, which is not visible in FIG. 11, is shown with closely spaced dashed lines. The widely spaced dotted lines show the lowest part of the winding 52c. As can be seen through the radii R ₂ , R ₁ , the valley bottom 86 only protrudes radially beyond the base of the spindle 52c. The valley bottom 86 is further configured such that the data line 4 is positioned radially outwardly in such a way that the front groove segment 82 of the laying groove 70c and also the rear groove segment 84 are radially guided without being twisted in both. Or is curved radially at the rear end, and is thus guided from the laying groove 70c, as shown in Fig. The loading of the twisted data line 4 to be prevented from forming and preventing waves is also reduced in this manner.

As can be seen from Fig. 9, the data line 4 is dragged across the radially outermost edge 54c of the inductive means 50c or underwater reel 30c during its extraction. The edge 54c is notched in the area of the laying groove 70c and this prevents the data line 4 from being drawn because the data line 4 is dragged across the notch during each turn. In order to keep such disturbance as small as possible, the circularly profiled outer edge 54c of the inductive means 50c, as seen from the back to the front in the direction of the inductive means 50c, But is only very finely spoken by the groove 70c. The small notch 88 still remains and is shown in FIG. However, its depth is less than 2 mm and this is furthermore realized in a tangential direction on both sides and very flat on both sides - less than 30 degrees on each side. In this manner, dragging the data line 4 across the notch 88 will only result in very little additional loading to the data line 4 during the draw. The depth of the notch 88 is less than 10% of the rising portion of the inductive means 50c on the lowest portion of the winding 52c of the reel 30c.

As can be seen in Figs. 9, 10 and 11, the rear groove segment 84 of the subsidiary groove 70c advances rearward in the axial direction in the tangential drawing direction of the data line 4. It is therefore possible to arrange the groove 70c in the rear groove segment 84 of its own backward direction so that it is realized as a wedge-shaped recess having a leading edge of a wedge pointing in the drawing direction without losing its groove shape in theory It is delivered. As a result, the data line 4 drawn out of the grooved groove 70c can be swung freely from the rear groove segment 84 without colliding with the edge. The rearwardly facing groove segment 84 is implemented with the forward tangential width being significantly greater than the axial width of the groove segment 82 to avoid damaging the data line 4 during rapid retrieval. The tangential width of the rear groove 70c in the rear region 84 is thereby at least 10 times the diameter of the data line 4 in the region of the transition segment 42.

The orientation of the front groove segment 82 has a tangential component since the data line 4 is dragged along the inductive means 50c during water withdrawal and therefore also across the anchoring groove 70c. The tangential component may refer to the direction component in the tangential direction of the front groove segment 82 relative to the side view of the inductive means 50c, which is vertical from above, as shown in Fig. Advantageously, the angle [beta] between the axial direction of the reel system 26c and the forward groove segment 82 is at least 45 [deg.], In particular 60 [deg.], Where at least 75 [deg.] Has proved to be particularly advantageous.

In order to protect the data line 4 being loosened, which is dragged across the laid grooves 70c, it is advantageous if the laid grooves 70c are at least partly covered, in particular in the front groove segments 82. This is caused by a tear-off membrane or other element. Additionally or alternatively, it is possible to fill the grooved groove 70c or its front groove segment 82 with silicon or a different material.

In its further course, the data line 4 is guided through the underwater reel 30c inwardly and forwardly to the air reel 28c. The data line 4 therefore advances radially inwardly from the winding package 36c of the underwater reel 30c through the rearward edge 54c and under its transitional segment 42c without releasing. On an additional course, the data line 4 is again directed forward through the outlet 60c to reach the winding package 36c of the air reel 28c.

The transitional segment 42c can be wound on the intermediate reel 78 to improve the withdrawal transition from the underwater reel 30c to the air reel 28c. The intermediate reel 78 includes, for example, only a single layer so that the data line 4 in the transition segment is drawn only once forward from the back through the intermediate winding 80. In a future course, the data line 4 is then led to the air reel 28c.

Figure 12 shows the intermediate reel 78 or its spindle 76 in perspective view. The data line 4, not shown in Figure 12, is wound on the lowest portion of the winding 90 of the intermediate reel 78, which is carried from the back to the front in its segment from the reel 30c to the air reel 28c All. When the data line reaches the front flange 92 of the spindle 76, it is guided to the laying groove 70d, which is machined into the forward facing flange 92. The flange can be implemented similar to flange 70b of underwater reel 34b. In the case of the exemplary embodiment shown in Fig. 12, the laying groove 70d has its own wedge-shaped end so that the data line 4 does not have to pass through any of the edges to pass into the laying groove 70d. In an axially flattened manner at the radially inwardly facing end. The laying groove 70d may also be circular in the axial direction at its radially outer end so as not to make any edges at the time of switching to the air reel 28c.

6, the radius of the lowest portion of the winding 90 of the intermediate reel 78 is smaller than the radius of the lowest portion of the winding 64 of the air reel 28c. This is likewise advantageously applied to the radial extent of the front flange 92 and of the rear flange 94 of the intermediate reel 78 as well. In this way, the air drawing from the air reel 28c is not disturbed.

Transitions between the underwater reel 30c and the air reel 28c are compensated or reduced by the intermediate reel 78 so that the data line 4 strikes the smaller waves during the transition during withdrawal, . The front side of the flange 94 may be conically shaped in the forward direction, similar to the guiding means 50, so as to allow less load on the data lines during the intermediate draw.

The data line 4 must travel from the air reel 28c to the reel 30c without transiting, i. E., Without splicing. This requires that the data line 4 be wound on one reel 30c on the air reel 28c and underwater. To achieve this, it is advantageous if the data line 4 is initially wound on the air reel 28c and then on the intermediate reel 78 while winding the reel system 26c. For this purpose, the housing 48c and the spindle 34c are removed.

It is advantageous if the water spindle 34c is wound when it is now separated from the housing 48c. For this purpose, it is proposed that the spindle 34c of the underwater reel 30c is held in its at least essentially corresponding position in its final mounting position with respect to the air reel 28c by the auxiliary retainer. Position variations within a smaller area of 2 to 3 millimeters can sometimes be tolerated thereby. The spindle 34c of the underwater reel can be attached to the housing 48c and the housing 48c is moved to the final position of the spindle 34c by approaching the spindle 34c . The spindle 34c is then attached to the housing 48c and the auxiliary retainer for holding the spindle 34c can be removed.
