Description

The invention relates to a coil system for a vehicle, in particular for a guided missile, comprising an underwater coil, which is prepared for a trigger in an underwater travel of the vehicle, an air coil, for a subsequent withdrawal in the air to a destination and for staying on Vehicle is prepared by then, and wound on both coils, continuous data conductor.

In the case of vehicles sent for a mission, it may be necessary for the vehicle to remain connected to a steering or control center during the entire mission period in order to be able to exchange image, status or navigation data. This can be realized by a data conductor, which is prepared as a data or signal transmission line for the transmission of signals. Because of the high transmission bandwidth and low signal attenuation at the same time, such data conductors are usually designed as optical waveguides. The data conductor is wound in a coil and connected to a spindle which carries the winding package. During travel or during the flight of the vehicle, the data conductor is unwound from the coil, so that the data connection between a transmitting or receiving station of the control center and the moving vehicle is maintained. In this case, the unwinding coil is usually arranged on or in the vehicle so that the unwound data conductor can remain as stationary as possible in the air or water space.

From the DE 10 2004 024 858 A1 Such a coil system is known. The vehicle is a missile that spends a first part of its mission underwater and a second part of its mission in the air. Accordingly, the coil system comprises an underwater coil, which remains connected to the guided missile during underwater travel and unwinds the data conductor. After the emergence of the missile from the water, the underwater coil is dropped with a buoy and the data conductor is unwound from an air coil, which remains during the flight on the missile. The buoy, which forms the transition between an underwater data conductor and an overhead data conductor, sinks onto the water surface on a parachute while the guided missile is approaching its destination.

In addition, other concepts are known from the prior art, in which vehicles are connected to other vehicles or launcher devices by means of data conductors for data transmission. In the DE 690 09 618 T2 It is proposed, inter alia, for airspace observation by a submarine, from this launch a missile for reconnaissance, the submarine and rocket are connected to each other via a fiber and both rocket and submarine and intermediate buoys can have coils with fiberglass , The DE 44 14 737 C1 proposes for wired remote control of a launched from a launcher missile or torpedo to provide both launcher and missile or torpedo with a supply reel with cable. In order to avoid demolition of an optical waveguide data conductor leading from a floating launching base to a floating missile discharge container as part of a remote control, reference is made to FIGS DE 38 18 840 C1 proposed the use of a device for Zugkraftentspannung. The DE 10 2004 034 309 A1 proposes the interposition of a befindliches under the water surface Spulenaufschwimmkörpers with an optical fiber coil to the optical fiber connection of an underwater vehicle with a launched from this active body. The DE 11 48 158 A deals with a guided over wire missile, which has a coil located inside it for the withdrawal of control line.

It is an object of the present invention to improve a coil system in terms of its handleability.

This object is achieved by coil system according to the features of patent claim 1. In this case, the underwater spool is fixed to the air-core of the air-core coil.

The invention is based on the consideration that the discharge of the underwater spool on the buoy is problematic. Thus, the data conductor should also be unwound during the descent of the buoy to the missile to compensate for the descent. This often leads to entanglement in the parachute or the buoy and thus a buckling of the data conductor, so that the signal transmission is disturbed or even interrupted. Once the buoy has reached the surface of the water, the data conductor, which is unwound in the air, sinks to the buoy on the surface of the water, becomes tangled to the buoy and is also kinked or torn by waves. Similar or similar problems occur when trying to keep the buoy below the water surface to make it difficult to detect.

The ejection resistant arrangement of the underwater spool on the air spool avoids these problems. Both coils remain on the vehicle and a buoy can be dispensed with. The data conductor is first unwound from the underwater coil and then from the air-core coil, the line transition from the winding package of the underwater coil to the winding package of the air-core coil expediently canister-free or buoys is executed. Tangling in the buoy or a separated underwater coil can be prevented.

The vehicle is prepared to be able to drive both in the water and in the air, while driving can also be understood as flying and / or diving. The vehicle may be a manned or unmanned missile and is conveniently provided with an underwater drive and / or an air drive, or a drive that powers both under and over the vehicle, such as a rocket engine.

The air coil and the underwater coil are two coils, each with its own winding package, which are preferably spaced from each other. The winding packages are designed so that in a deduction first the winding package of the underwater coil is completely unwound and then the winding package of the air-core coil is completely unwound - when the winding of the coil system is complete.

The underwater bobbin is prepared for takeoff during underwater travel of the vehicle, particularly an underwater flight powered by a rocket engine. Such a preparation implies that the unwinding of the underwater bobbin, that is to say the withdrawal of the underwater bobbin, proceeds at this speed without kinking of the data conductor - and thus without data loss during normal signal transmission - and even more without a demolition of the data conductor, so that the signal transmission is error-free can be maintained.

The air-core coil is prepared for extraction in the air to a destination. So it is located at the trigger in the air, firmly attached to a component of the vehicle. If the vehicle is a guided missile, then the trigger should go smoothly and reliably up to a maximum speed typical for the missile, for example, up to a speed of 250 m / s. The length of the data conductor should be at least five kilometers, in particular at least 20 kilometers.

The underwater spool is fixed to the air-core coil. This implies that a release of the underwater spool from the air-core coil during normal operation is not provided and is also not possible in error-free operation. The underwater coil is expediently fixed to the air-core coil so that it can only be separated from the air-core coil on the ground and in particular only with tools. An ejection mechanism for an automated or manual ejection does not exist. The underwater spool is thus carried along to the destination during the drive of the vehicle, in particular during the flight of the guided missile. In other words, the underwater spool remains attached to the air-core spool even when the air-core spool is already being unwound, in particular at least half of it has already been unwound.

The underwater coil is expediently attached at least partially behind the air-core coil. Such an arrangement is favorable, since the data conductor is expediently generally unwound first from the underwater coil and only then from the air-core coil, while the vehicle fulfills its mission. The direction here refers to the direction of travel of the vehicle or its construction, so that the rear is arranged behind the top of the vehicle.

A spool consists at least of a spindle and a winding package and can optionally have a housing which at least partially shields the winding package from the outside. The winding package includes the wound data conductor in a plurality of turns. The spindle may be an external take-off spindle or an internal take-off spindle, the winding package being arranged radially outside the spindle in the case of an external withdrawal spindle, the data conductor thus being wound onto the spindle, and the winding package being arranged radially inside the spindle in the case of an internal withdrawal spindle. In this case, the data conductor is usually first wound as a winding package and this is then used in the internal withdrawal spindle, which surrounds the winding package radially outside and thus can also fulfill a housing function. The inner trigger spindle and the outer trigger spindle are also referred to below as the inner spindle and outer spindle.

The data conductor expediently comprises a data line body, in particular a light pipe body, such as a glass body. The data line body may be surrounded by a shielding body, for example another glass body with a different refractive index, so that a reflecting plane is created within which the data-carrying radiation remains. In the case of an electrical signal, a metallic shielding body is also possible. The data conductor also suitably comprises an outwardly protective sheath, for example in the form of a plastic coating, a textile sheath or a sheath with fibrous tissue. Within the shell, a stabilizing element may be arranged, for example a stable thread, which improves the data conductor with regard to its tensile strength.

The data manager is a continuous ladder, so he goes from the beginning of the Underwater coil through to the end of the air coil, without opening into a receiving station, such as an amplifier or other electronic component. He may have a splice, z. B. between the winding packages of the two coils, that is, a connection point, are connected to the signal transmission capable of two previously separated data conductor parts. Conveniently, however, the data conductor passes spliceless from one winding package to the other, in particular the data conductor is spliceless from the beginning of the underwater spool to the end of the air-core spool, so that the winding packages are also spliceless.

The data conductor can be divided into an underwater conductor and an air conductor, wherein the underwater conductor expediently made thicker, for example, thicker jacketed is. As a result, a greater withdrawal resistance under water can be taken into account. However, a strict separation of the conductor types on the winding packages is not absolutely necessary, so that, for example, the thicker underwater data conductor can still be inserted into the winding package of the air-core coil and, for example, can form several layers of the air-core coil. This is particularly useful if there is the possibility that the data conductor is also unwound during an underwater ride of the air coil and thereby exposed to increased friction or withdrawal resistance.

The two coils can form a system in which, for example, the spindles of the two coils directly adjacent to each other and are separated from each other, for example, only by a paragraph. A common, one-piece spindle for both coils is possible. In general, the underwater spindle is expediently screwed or welded to the housing or the spindle of the air-core coil, so that a firm cohesion is ensured.

Both coils can form an internal cavity through which an engine jet is guided during the flight of the missile. In particular, in the embodiment of the underwater spindle as the outer spindle, an engine beam guide can be guided transitionless through the two spindles. However, it is also possible that the spindle of the underwater spool is attached to a housing of the air-core coil. The underwater spindle may be internal spindle or external spindle, depending on the design of the underwater coil.

The underwater spool can protrude out of the housing of the air-core coil and, in particular, protrude out of a housing of the guided missile. However, it is also possible that the housing of the air coil and the underwater coil at least partially surrounds housing and thus protects. The housing must not be made in one piece, but an outer surface of the housing expediently forms an outer surface of the vehicle or the missile.

In an advantageous embodiment of the invention, the underwater coil is an internal withdrawal coil. With this configuration can be counteracted tangling in the settlement of the underwater coil under water, ie at an underwater discharge. This aspect of the invention is based on the consideration that in an air outlet and also in an underwater extraction there is always the risk of multiple extraction, ie the simultaneous withdrawal of several turns, so that a free coil of wire is formed. This easily leads to a kinking of the conductor. In order to prevent multiple withdrawal at an outer coil, the winding package is expediently designed to be backwards, ie towards the withdrawal direction, tapered, so that a sharp winding edge towards the rear is avoided as possible. With a draft, this shape is sufficient, because at high speed, the effect occurs that the unwinding data conductor is thrown by the high unwinding speed and the associated high centrifugal force during the unwinding rotating outwards and thus stands out from the underlying layers. As a result, a multiple deduction is counteracted in the air. When unwinding under water, however, it has been shown that this centrifugal force effect is not sufficient to lift the data conductor sufficiently from the underlying winding layers. A pulled back data conductor is therefore easily unwound with a too small radius, so that it subtracts underlying layers. In addition, small radii cause the signal transmission is hindered or prevented. These problems can be counteracted with an internal trigger. A radially inwardly withdrawn data conductor has the much greater tendency to stand out from the underlying or radially outward Windungslagen. The trigger resistance is lower and thereby also the narrowest radius of the data conductor at the point of the momentary detachment of the data conductor from the winding package to the inside. By the inner take-off reel, a trouble-free data transfer operation can thus be more easily ensured.

Advantageously, an inner diameter of the discharge opening of the underwater coil is greater than the outer diameter of the discharge opening of the air coil to the rear. As a result, on the one hand a larger package volume of the winding package and thus with a long line and an axially shorter underwater winding can be achieved. In addition, the Data conductors - depending on the design of the vehicle - radially more easily spaced from an inner engine jet. The discharge opening of the air coil to the rear is in this case that opening through which the data conductor is guided in an unwinding from the air coil to the rear and out of the housing of the air coil out.

A further advantageous embodiment of the invention provides that a conductor transition from the winding package of the underwater coil to the winding package of the air-core coil is fixed on the winding package of the air-core coil. The fixation can be done for example by a bond or a fixation using a thread. In the case of bonding another, especially firmer bonding is useful, as such, with which the turns of the air coil are glued together. With this aspect of the invention, the following problem can be solved: During underwater travel of the vehicle, the air coil is flooded, since the housing of the air coil must be open to the rear to allow a trigger. In order to prevent flooding from back to front, it is possible to provide the housing of the air coil with front openings through which the water can flow in at the front and flow backwards. Experiments have shown that the water flowing back out of the air-core coil at the conductor transition tugs. This is particularly exposed to the passing water, because it must be lifted from the air spool to be led to the underwater coil. In this respect, attack at this conductor transition greater forces by the passing water, as at the other turns of the air coil. If this conductor transition loosens unintentionally from the air-core coil or from the underwater coil, then a coil of wire can quickly form uncontrollably in the region of one or the other coil. This tangle disturbs the unwinding of the conductor so that the data conductor gets tangled. Now, if this conductor junction adhered to the air coil, it can be counteracted by water flowing past. Advantageously, an adhesive is used for bonding which dissolves more easily at a higher peel rate than at a lower peel rate. Under lighter here is a force to understand, with the conductor transition can be detached from the underlying turns of the air coil.

It is also advantageous if a conductor transition from the winding package of the underwater coil to the winding package of the air-core coil is guided at least partially transversely to the windings of the air-core coil. As a result, the conductor transition offers a lower resistance to the passing water, so that the conductor transition is easier to fix. Under transverse here is an angle of at least 70 °, in particular a right angle to the windings of the air coil to understand.

Although it may be that the conductor transition at such locations, which do not run across the turns, still provide a relatively high resistance to attack by the passing water. Due to the transverse laying, however, a firm fixation of the conductor transition on the air-core coil can be ensured over a relatively large distance, so that inadvertent detachment by the passing water is counteracted.

The removal of the conductor from a coil under water is associated with high friction and thus with the risk of kinking of the data conductor. Although this danger can be reduced with an inner coil, it may be advantageous to use an outer withdrawal coil as the underwater coil. Appropriate measures can prevent kinking or unwanted multiple deduction, such as slow peeling, gluing of the coils to one another well adapted to the take-off speed, and / or a conically tapered spindle geometry, thereby facilitating the lifting of the data conductor from the underlying turns.

In particular, in the case of an underwater coil which is designed as an outer withdrawal coil, it is advantageous if the winding bottom of the underwater coil lies radially inside the winding bottom of the air-core coil. When the air-core is withdrawn, the data conductor can easily be guided radially outwardly of the underwater spindle and expediently without contact, so that damage to the data conductor is avoided even at very high take-off speeds.

Further, it is advantageous if the diameter of a separation aid or a steering means of the underwater coil is smaller than the diameter of the innermost layer of the winding package of the air-core coil. As a result, the data conductor of the underwater coil can be unwound from the air-core coil. In particular, it is advantageous if the diameter of the radially outermost layer of the winding package of the underwater coil is smaller than the diameter of the innermost layer of the winding package of the air-core coil. With this aspect of the invention, a steering means for directing the data conductor drawn from the underwater spool may protrude radially outwardly beyond the outermost windings over the outermost layer of the underwater spool, without disturbing the air vent. The data conductor can be handled by the air coil in this case without jerk.

In order to prevent a multiple take-off of the underwater coil, ie a withdrawal of several turns at the same time and also counteract buckling of the data conductor, it is advantageous if the underwater coil has a steering means which the withdrawing conductor radially outward, for example, the underlying layer or the Winding bottom takes off. Although a similar effect can be achieved by a conical leakage of the winding package to the rear, but this design has the disadvantage that it builds axially longer. By the steering means so a compact axial design of the underwater coil can be connected to a reliable underwater discharge.

As a steering means such means are suitable, which ensure that the data conductor at the point where it is released from the winding package, at least a little bit is lifted radially outward. Particularly simple is an embodiment of the steering means such that it is a rear, radially projecting collar. This can, for example, stand directly from the winding bottom or from another element of the underwater coil or another unit. The collar may be a rear, tangentially encircling and radially outwardly directed formation and may be part of the underwater coil, for example. Possible, for example, a flange in the manner of steel construction. Expediently, the steering means projects radially beyond the outermost turn of the underwater coil.

In order to avoid a disturbance of the air exhaust from the air-core coil, it is advantageous if the steering means lies completely radially inside the winding bottom of the air-core coil, that is to say that it projects radially beyond the winding bottom of the air-core coil. The axial position is independent of this. In this way it can be ensured that even if the data conductor is subtracted from the bottom layer of the air coil, prevents contact with the steering means in an air outlet and thus a trouble-free signal transmission is maintained by the data conductor.

In order to counteract a kinking of the data conductor in an underwater discharge, it is also advantageous if the steering means is chamfered to the winding package of the underwater coil. Conveniently, the slope is designed so that it forms an angle to the winding bottom of the underwater coil greater than 120 °. The bevel suitably extends as far as the winding bottom, wherein a small step in the height of a maximum of two winding layers is harmless in this case. The bevel may be a conical surface, which is expediently rounded radially outward in the profile. The data conductor can grind along the chamfer and round without bending or kinking with too small a radius.

During underwater travel of the vehicle, both coils are usually wet, as well as they dip into the water. Depending on the design of the data conductor, the envelope of the data conductor, for example in the case of a textile wrapping or wrapping with fibrous tissue, sucks up with water. This can lead to the fact that the thickness of the data conductor increases and thus a winding package of a coil builds up a certain pressure. While the windings readily withstand such pressure, the pressure for a transition portion of the data conductor from the underwater spool winding package to the air package winding package may be problematic.

In order to counteract undesired stress on the data conductor, it is advantageous if the transition of the data conductor from the winding package of the underwater coil to the winding package of the air-core coil is inserted into a laying channel. In the sensitive transition area, the data conductor can be protected by the laying channel and prevented from buckling. The laying channel can be incorporated in the underwater spool, for example in a front or rear flange of the underwater spool. Conveniently, the laying channel is attached where the winding package of the underwater coil to an axial boundary surface, such as a flange, adjacent. Advantageously, the laying channel is guided to the radially upper end of the boundary surface, for example of the flange. Further, it is advantageous if the laying channel extends to the winding base, so that the head of the lowest layer can be inserted directly into the laying channel.

Further, it is advantageous if the direction of the laying channel has a tangential component in order to allow a smooth directional transition to the tangential winding direction of the data conductor on the winding base. Appropriately, the orientation of the laying channel is inclined by a maximum of 30 °, in particular a maximum of 15 °, for aligning the winding base at the place where the laying channel reaches the winding base. In this case, the laying channel can advantageously be designed to be at least substantially rectilinear or curved.

A further advantageous embodiment of the invention provides that the underwater coil is arranged so relative to the air-core coil that the data conductor is withdrawn radially from the air-core spindle inside the spindle of the underwater coil and through it as a result of a regular withdrawal.

The underwater coil thus forms an inner opening through which the data conductor is guided. A Such an arrangement has the advantage that the winding package of the underwater coil can be radially relatively large and thus axially compact and also a relatively large radial distance of the unwound data conductor can be made by a jet engine.

Further, it is advantageous if the winding package of the underwater coil is arranged partially behind the winding package of the air-core coil. By an axial overlap of the two winding packages, an axially compact arrangement can be achieved in the system, so that the vehicle or the missile can be made axially compact.

Conveniently, the coil bottom of the underwater coil is located radially outside of the winding bottom of the air coil, the circumference of the winding bottom of the underwater coil is thus greater than the circumference of the winding bottom of the air coil. The winding bottom of the underwater coil can here be arranged completely or partially behind the winding bottom of the air-core coil.

A compact and mechanically stable design of the winding system can be achieved if the spindle of the underwater coil is attached to a housing of the air-core coil. A holding power flow between the coils thus passes through the housing. In this case, between the air-core coil and the spindle of the underwater coil there can be an air space through which the data conductor drawn off from the air-core coil passes. Such a vent air space separates the two spindles of the two coils.

Also, a compact design, it is beneficial if the spindle of the underwater coil forms a housing portion of the air coil. This housing section is expediently brought together conically to the rear, so that therefore reduces the inner diameter of the housing to the inside, the spindle thus forms a part of the rearwardly tapered housing. The spindle can be made multi-layered, so that the material of the housing is different than the material of the winding bottom of the underwater coil.

Advantageously, a transition section of the data conductor from the winding package of the underwater coil to the winding package of the air coil from the underwater coil is first led to the rear and then radially through the spindle of the underwater coil to the front. This arrangement is expediently maintained even if no piece of data conductor from the underwater coil, let alone from the air-core coil, unwound.

A large winding packet volume and thus a long data conductor in the underwater coil can be achieved if the winding bottom of the spindle of the underwater coil is located radially further outside than at least inner parts of the winding package of the air coil.

When the data conductor is removed from the underwater spool and the air-core coil, the data conductor is subjected to a great load because of the high take-off speeds. In particular, during the transition of the trigger from the underwater coil to the air coil, the withdrawn data conductor forms waves which contribute to an increase in the load. In order to keep such waves small, it is advantageous if the data conductor is guided in a transition region from the winding package of the underwater coil to the winding package of the air-core coil in a depression, which can be designed, for example, in the form of a groove and is referred to below as a laying channel. The recess or laying channel may be arranged at the rear end of the underwater coil, for example in a rear steering means of the underwater coil, which may be designed as a flange or generally as a radial projection on the winding bottom. The laying channel is expediently guided to a radially upper end of the steering means and lies on the winding package facing side of the steering means.

Further, it is advantageous if the laying channel has a first winding package facing portion and a second rearwardly facing portion. Both sections can be arranged in the steering means. The data conductor is expediently laid in both sections.

A particularly strong deduction load of the data conductor can be avoided if the laying hole pierces a steering means in the rear part of the underwater coil in the region of the largest radial extent of the steering means as in a valley. The data conductor removed from the laying channel does not form a wave as large as without the laying channel.

In order to keep the shaft small, the laying channel should cut deeply into the steering means. It is advantageous if the radial elevation of the valley bottom a maximum of 30% of the survey of the steering means beyond the spindle bottom of the underwater spool beyond the spindle bottom. However, the bottom of the valley can also be located radially lower than the spindle bottom or winding bottom of the underwater coil.

When deducting from the underwater spool, it may be that the data conductor is looped over the edge of the steering means. To keep loads on the data conductor low, the edge along the circumference should therefore be as even as possible. This can be achieved if the circularly extending outer edge of the steering means is notched by the laying - from rear to front on the steering means - radially maximally 20% of the collection of the steering means on the spindle bottom of the underwater coil, suitably not more than 5 mm, in particular maximum 2 mm.

A discontinuity in the course of the data conductor, such as a kink in the data conductor, can lead to a wave during the deduction and thus to an increased deduction load of the data conductor. In order to keep this low, it is advantageous if the base of the laying channel is radially curved at its rear end in such a way that the data conductor is guided radially kink-free in the laying channel and also radially kink-free emerges from it.

If the trigger point of the data conductor passes the rear steering means and runs radially inward behind the steering means, the data conductor will deflect slightly in the tangential direction due to the change in direction of the trigger point. In order to avoid a bumping of the data conductor at an edge of the rear region of the laying channel, it is premature if the rearwardly facing portion of the laying channel terminates in the tangential withdrawal direction of the data conductor axially to the rear.

A uniform course of the data conductor connected to a smooth outer edge of the steering means can be achieved if the section facing the winding package is oriented at an angle of at least 75 ° to the axial direction of the coil system, if possible over most of its total length, in particular over the entire length of the front area or section of the laying channel.

In embodiments in which the rear end of the air-core coil lies in the axial direction in front of the rear end of the underwater spool, it is advantageous if the data conductor is wound up between the underwater spool and the air-core spool on an intermediate spool. The intermediate coil may have an intermediate winding consisting of only one layer.

In order not to disturb a trigger from the air-core coil, the intermediate winding on the intermediate coil is expediently arranged completely radially inside the winding bottom of the air-core coil. Conveniently, the intermediate coil is provided on a front flange with a laying channel in which the data conductor is laid.

In addition, the invention is directed to a vehicle, in particular a guided missile with a rocket engine, with a coil system arranged at the rear, in particular as described above, according to the features of claim 24. It is proposed that one prepared for a deduction in an underwater travel of the vehicle Underwater spool of the coil system Abwurffest is attached to the rear. Conveniently, the coil system is arranged at the rear of the vehicle and in particular about an engine jet space.

Furthermore, the invention is directed to a method for maintaining a data connection between a moving vehicle, in particular a flying missile, and a control center, in particular a launching station, via a data conductor, in which the data conductor is withdrawn from an underwater coil during underwater travel of the vehicle Vehicle enters the air through the water surface and the data conductor is withdrawn from an air coil during an overwater journey. The control center can be in a building or a vehicle, for example in a submarine.

It is proposed that the underwater coil according to the invention remains firmly connected to the air-core coil during subsea and surface navigation up to a destination of the vehicle. It can be dispensed with the dropping of an interface, such as a buoy, whereby a tangling of the data conductor can be prevented.

The air extraction is expediently until the vehicle reaches a predetermined destination, for example after a flight phase. Advantageously, a portion of the underwater coil is still withdrawn in the air.

Furthermore, the invention is directed to a method for winding a coil system with a data conductor, which is designed to hold a data connection between a moving vehicle, in particular a flying missile, and a control center, according to the features of claim 25, wherein the data conductor first on a spindle of an air coil and then wound on a spindle of an underwater spool of the coil system.

To counteract a demolition of the data conductor in a unwinding, it is advantageous if it is wound up in one piece on the underwater spool and the air-core coil. For this purpose, both coils must be wound with a continuous data conductor. To achieve this, it is proposed that the spindle of the underwater coil according to the invention is held during winding in a position in which between its and the spindle of the air coil, a discharge opening for outputting the data conductor in a withdrawal from the air coil is present.

Advantageously, the spindle of the underwater spool is held in its winding position by an auxiliary holder during winding, wherein the auxiliary holder is removed after winding and the spindle is then fixed ready for operation on the air-core coil. The attachment can be attached indirectly or advantageously indirectly, in particular via a housing of the vehicle to the air coil.

To attach the underwater coil to the air coil, the two coils expediently remain immovable to each other during attachment. For attachment, a third element is attached to the underwater spool and the air-core coil for attachment to each other. Conveniently, this third element is a housing of the vehicle. Conveniently, the air coil is attached directly to the housing of the vehicle, wherein the air coil is expediently indirectly, that is attached via one or more further elements to the housing of the vehicle.

The guided missile was made of a torpedo tube 8th launched the submarine, which forms a launching station for the guided missile. The guided missile has under a water surface 10 an mission-dependent route 12 , For example, 400 m, covered. After covering the underwater stretch 12 the guided missile has changed its direction of travel, the water surface 10 pierced and now sets his ride above the water surface 10 towards a destination 14 continued. The destination is for example 25 km from the control center 6 away, with the vast majority of this distance from the vehicle 2 is covered in the air.

The data manager 4 is in the submarine at an interface 16 attached and signaling via a further data connection with a control unit 18 the control center 6 connected. The control unit 18 controls a flight of the vehicle 2 both under water and over water and processed by a seeker head 20 of the vehicle 2 generated image data that the seeker 20 during the flight. The control unit 18 is about the data conductor 4 signaling technology with a control unit 22 connected inside the vehicle 2 is arranged. This control unit 22 controls the flight of the vehicle 2 about rudder 24 , where the control commands from the control center 6 over the data conductor 4 to the control unit 22 be transmitted. The data of the seeker 20 turn over the data conductor 4 to the control center 6 transmit, which generates the control commands.

the interface 16 has a coil, not shown, for outputting the data conductor 4 on to a movement of the control center 6 relative to the surrounding water, without the data conductor 4 is pulled through the water. The largest part of the data manager 4 However, this is due to a coil system 26 spent at the rear of the vehicle 2 arranged and in 2 is shown in more detail.

2 shows the back part of the coil system 26 of the vehicle 2 out 1 in a longitudinal section. In 2 is the coil system with the reference numeral 26a Mistake. In the following embodiments, similar components with the same reference number but depending on the embodiment with other reference letters are marked, if the components have slight differences, for. B. in size, position and / or function. If the reference number alone is mentioned without a reference letter, then the corresponding components of all embodiments are addressed.

The coil system 26a includes an air coil 28a and an underwater spool 30a , in this embodiment completely behind the air-core coil 28a is arranged. While the air coil 28a designed as Außenabzugssspule, is the underwater coil 30a configured as an inner withdrawal coil.

The data manager 4 is both on the air coil 28a as well as on the underwater spool 30a wound up and is uninterrupted, in particular spliceless, on both coils 28a . 30a continuous. The air coil 28a includes a spindle 32a on which the data manager 4 Layered by layer. Also the underwater coil 30 is with a spindle 34a equipped, however, which is designed in this embodiment as an inner spindle, so a spindle, the winding package 36a the underwater spool 30a surrounds radially from the outside. In contrast, the spindle 32a the air coil 28a radially inside the winding package 38a the air coil 28a arranged.

The data manager 4 is divided into three sections: The winding package 36a forms an underwater section 40 of the data manager 4 who is at the interface 16 the control center 6 begins, until the winding package 36a ranges and this forms. A transitional section 42a connects the wrapping package 36a with the winding package 38a the air coil 28a , An air section 44 of the data manager 4 forms the winding package 38a and reaches to the control unit 22 , The transition section 42a can also have some turns of the air coil 28a form. All three sections 40 . 42a . 44 are traversed by a single, continuous optical fiber, the splice-free through the three sections 40 . 42a . 44 is guided. Only the sheath of the data conductor 4 varies in sections 40 . 42a . 44 , The sheathing is in the sections 40 . 42a thicker than in the air section 44 , This is the data conductor 4 in these two back sections 40 . 42a more tear resistant than in the air section 44 , However, the air section can 44 be subtracted faster by its slimmer and lighter design, which is particularly advantageous for the air vent.

While the missile 2 During underwater travel at a certain speed through the water and the underwater coil 30a is processed at the appropriate speed, the deduction of the data conductor 4 after piercing the water surface 10 considerably accelerated as the missile 2 during his flight to the destination 14 Speeds up to 250 m / s.

During the entire flight, both above water and under water, the underwater spool remains 30a with her spindle 34a - except for the completed part of the data manager 4 - at the vehicle 2 , For this purpose, the spindle 34a firmly with the other components of the vehicle 2 connected, in this embodiment, with the outer housing 48a of the guided missile 2 , which is also the case 48a the air coil 28a forms. The spindle 34 is with the case 48a firmly screwed and thus not solvable during the flight of the missile. It can only after removal of the winding package 36a with the help of tools from the rest of the vehicle 2 be separated, which is not provided in regular operation. Alternatively, it is also conceivable that the underwater coil 30a or their spindle 34 with the vehicle 2 is welded.

To avoid unwanted multiple deduction and a radial lifting of the deducted data conductor 4 from the underlying turns of the winding package 36a To facilitate, is the underwater coil 30 or their spindle 34a with a steering means 50a formed in the form of a flange integral with the winding bottom 52a the spindle 34a connected is. In an underwater deduction, the data conductor drags 4 over the rounded edge 54a of the flange 50a and is thereby lifted obliquely radially inward from the underlying winding layer. The steering means 50a In this case, it is designed as a radially inwardly pointing shape, which in this case continues inward than the furthest inner winding layer of the winding package 36a the underwater spool 30a protrudes, so that the radially innermost position of the data conductor 4 is drawn in the trigger a little way inward. However, the radius of the steering means should be 50a at the narrowest point, ie at the edge 54a , greater than the outer radius of the discharge opening 60a be so that differs from the air coil 28 unwinding data ladder 4 not to the edge 54a abuts. Particularly suitable is a radius which is at least 1.1 times the outer radius of the discharge opening 60a is.

In addition, this causes steering means 50a that the winding package 36a does not have to be thinner radially to the rear to avoid multiple deductions. The steering means 50a limits the winding package 36a back so that an unwanted multiple deduction is thereby avoided by itself. In addition borders the winding package 36 at least substantially unrestrained to the steering means 50a at.

When immersed in the water, the interior becomes 56 around the air-core coil 28a or within the housing 48a flooded with water through openings 58 in this interior 56 flows. The water flows backwards and through a discharge opening 60a back out of the case 48a the air coil 28a out. The flowing water pulls on the windings of the winding package 38a the air coil 28a , However, the data conductor is within the winding packages 36a . 38a glued, the individual turns of the data conductor 4 So they are glued together, so a stable winding package 36a . 38a arises. The bond is chosen so that the data conductor 4 not too strongly kinked in a trigger, so as not to jeopardize the data transfer. On the other hand, the bond is so strong that the corresponding winding package 36a . 38a Also sufficiently holds together under water and does not create a multiple deduction by loose turns.

However, the transitional section 42a led a little way through the air, so that the flowing water at this section 42a stronger rips. To entrain the transitional section 42a of the data manager 4 Avoiding with the moving water is part of the transitional section 42a with the underlying turns 62 the air coil 28a glued solid, as the turns 62 are glued together. For this purpose, an adhesive is used, which is a detachment of the bonded data conductor 4 at a fast peel rate with less force than at a slower peel rate. The glue can be a silicone that winds between turns 62 and transition section 42a is added.

Moreover, part of the transitional section 42a transverse, namely perpendicular to the winding direction of the turns 62 , guided in order to achieve the longest possible gluing distance. Even if that's through the interior 56 shooting water very strongly at the rear part of the transition section 42a pulls, so remains the transversely oriented part of the transitional section 42a but firmly with the turns 62 connected so that the data conductor 4 by the einschießende water is not undesirable from the underlying turns 62 the air coil 28a is replaced.

The transition section 42a extends some distance into the winding package 38a the air coil 28a and forms part of the uppermost layer of the windings of the air-core coil 28a , This will allow the air coil 28a as far as the transition section 42a can be deducted under water without the data conductor 4 is impaired. That to the transition section 42a said is also for the transitional sections 42b and 42c applicable.

The air coil 28a is an outer coil containing a plurality of winding layers extending parallel to the spindle bottom or winding bottom. They form the winding package 38a which is tapered backwards to avoid unwanted multiple deduction of back turns.

When driving the vehicle 2 this is initially fired from the launching station, the data conductor essentially from the underwater coil 30a , but also something of the coil of the interface 16 is handled. The unwinding takes place here by the tensile force, which is the moving vehicle 2 on the data conductor 4 exercise, so that this unwinds by itself.

The length of the underwater section 40 of the data manager 4 is such that the set route 12 under water ± 30 m longer or shorter than the length of the underwater section 40 is. When the vehicle appears 2 from the water so the underwater coil is at least substantially completely unwound. Is still data ladder when surfacing 4 on the underwater spool 30a so this is unwound in the longest first 30 m above water in which the vehicle 2 not yet so fast is that the settlement or the deduction of the underwater coil 30a would be problematic. On the other hand, the underwater ride is not over when the underwater spool 30a is completed, so can still the distance of a few meters transition ladder 42a from the air-core coil 28a unwound which can withstand the high mechanical load of the underwater outlet.

3 shows another coil system 26b with an air coil 28b and an underwater spool 30b , The description of the following exemplary embodiments is essentially limited to the differences from the exemplary embodiment in FIG 2 which is referred to with regard to features and functions that remain the same. Substantially identical components are basically numbered with the same reference numerals, and features not mentioned are adopted in the following exemplary embodiments without being described again.

While the air coil 28b is executed substantially the same as the air coil 28a out 2 , is the underwater coil 30b an outer withdrawal coil. It is essentially outside the case 48b arranged, as well as the openings 58 , same as in the embodiment 2 can be designed. The winding package 36b the underwater spool 30b is like the wrapping package 36a the underwater spool 30a wound in a plurality of layers, but in the embodiment of 3 from the inside out, so the data conductor 4 is processed from outside to inside.

In the general case, the spindle 34b the underwater spool 30b with the spindle 32b the air coil 28b directly connected or both spindles 32b . 34b are integrally connected, so at least their winding floors 64b . 52b are one piece. The spindles 32b . 34b can be made of metal or plastic for special applications.

Both coils 28b . 30b are designed as hollow coils and hold a tubular cavity 68 ( 4 ), so that the Gasleitrohr the missile or the rocket engine can lie in the missile axis. The engine jet is thus through the coils 28b . 30b passed.

In order to avoid an unwanted multiple trigger at a water outlet, the underwater coil 30b with a steering means 50b executed at its rear end. This is all around radially over the entire circumference on the outermost layer of the winding package 36b out, like in 3 that the wrapping package 36b indicated by dashed lines, is shown. The deduction becomes the data manager 4 over the outer rounded edge 54b of the conductive agent 50b looped so that the radially protruding edge 54b a lifting of the unwinding data conductor 4 caused by the underlying layer. This will cause the friction of the data conductor 4 kept low while peeling off so that the data conductor 4 is not kinked and the signal transmission can be maintained trouble-free. In addition, the steering means causes 50b that the winding package 36b Also bordered to the rear, so that the rear turns not in an unwanted multiple deduction the winding package 36b can leave and become the data manager 4 tangled.

To ensure a trouble-free air extraction, the entire winding package 36b the underwater spool 30b radially inside the winding package 38b the air coil 28b arranged. The radially outermost layer of the winding package 36b So is radially within the radially innermost layer of the winding package 38b arranged. Next is also the steering means 50b dimensioned in its radial extent so that it does not protrude radially further than the winding bottom 64b the air coil 28b , This ensures that the of the air coil 28b withdrawn data conductors 4 not to the underwater spool 30b and in particular their steering means 50b abuts. For a non-impact deduction of the data conductor 4 from the air-core coil 38b has an outer diameter d of the steering means 50b of d = (0.8 ± 0.1) D, where D is the diameter of the winding bottom 64b the air coil 28b is.

However, it is also possible that the steering means 50b Although a little way over the winding floor 64 radially protrudes, but everywhere at least 3 mm radially within the outer circumference of the discharge opening 60b remains. Because the air outlet is the data conductor 4 torn by the rotating trigger and the centrifugal forces acting outward and lies in the region of the discharge opening 60b at the rounded inner edge of the housing 48 at. Is this inner edge sufficiently far from the winding bottom 64b removed, becomes the data manager 4 So even with a radially slightly above the winding bottom 64b protruding edge 54b or the steering means 50b the underwater spool 30b led around.

The spindle 34b the underwater spool 30b is in 4 shown in a perspective view. 5 shows the spindle 34b in a side view. The winding floor 52b is between a front flange 66b and the rear steering means designed as a flange 50b arranged so that the winding package 36b between these two flanges 50b . 66b is held. A not directly deducted turn of the winding package 36b is therefore - even if it should slip axially - between the two flanges 50b . 66b captured. A drop from the winding package 36b or multiple deduction is not possible.

How out 5 you can see that is the winding package 36b pointing flange side to the radial direction inclined by the angle α. This angle reduces the bending radius of the over the edge 54b pulled data conductor, so that the data transmission even in a very busy data conductor 4 takes place without interference. The greater the maximum speed of the vehicle under water, the larger the angle α should be. On the other hand, takes a larger angle α at the same axial length of the underwater coil 30b Space for the winding package 36b away, so that different spindles or coils for different speed underwater rides are useful.

In this respect, the invention is generally also directed to a system of at least two vessels having a different design maximum speed under water. The vehicles are each equipped with a coil system according to the invention, wherein the angle α of the inclination of the rear steering means 50b to the radial direction is higher in the vehicle with the higher maximum speed than in the vehicle with the lower maximum speed.

To achieve a high positional stability, the winding package 36b directly forward to the rear wall of the flange 66b led, so is due to this. The trailing edge of the front flange 66b can be perpendicular to the winding bottom 52b run, so that there is a large changing room. In this area is the data manager 4 from the radially innermost layer of the winding package 36b radially outward to the air coil 28b led, so he must between winding package 36b and flange 66b be led up. Quill now the winding package 36b as a result of the wetting with water, it exerts a pressure on the rear wall of the flange 66b and squeezes the data conductor 4 between winding package 36b and flange 66b one. This can in particular in the radially inner region to a buckling of the data conductor 4 to lead.

To prevent this is the winding package 36b front-limiting flange 66b with a laying person 70b designed. This is as a recess in the rearwardly facing surface of the flange 66b incorporated and extends radially inward to the winding bottom 52b , The laying thing 70b is provided in its orientation with a tangential component, so that the data conductor 4 with a sufficiently large radius taut from the winding bottom 52b through the laying waste 70b can be guided radially outward. Accordingly, the laying empties 70b with its radially outwardly facing surface just before the winding bottom 52b in a rounding 72 and gives the curvature of the curve 72 along the data guide 4 in front.

When removing the underwater spool 30b So it will be the last layer of the winding package 36b subtracted from the back to the front and then the piece of the data conductor 4 from the laying house 70b pulled, what immediately the peeling off the glued transition section 42a initiates.

The laying thing 70b has the depth of at least 0.8 of the diameter of the data conductor 4 in transitional section 42a , Thus the crosswise to the laying person 70b running underwater section 40 of the data manager 4 in the wrapping package 36b not over the edges of the laying channel 70b should be bent, should also be the width of the laying 70b be chosen small. It should not exceed five times the diameter of the data conductor 4 in the transition section 42a in particular, only a maximum of two times. Particularly advantageous is a ratio of the groove width to the data line diameter between 1 and 2, in particular between 1.2 and 1.6.

Appropriately, is also the underwater coil 30a of the coil system 26a equipped with a laying channel. This can be carried out exactly as the laying channel 70b out 4 , being in the front flange of the spindle 34a can be incorporated and depending on the design in the housing 48a , as in the embodiment of 2 would be useful. In any case, the laying channel would be incorporated in the component, directly to the winding package 36a connects and this limited to the front.

Another embodiment of a coil system 26c is in 6 shown. The coil system 26c in turn has an air coil 28c and an underwater spool 30c , The air coil 28c can - except for the case 48c - Be executed the same as the previous air coils 28a . 28b , The underwater spool 30c is designed as an external coil, but radially outside the winding bottom 64c the air coil 28c arranged. Here is the winding bottom 52c and therefore also the entire winding package 36c the underwater spool 30c radially outside the winding bottom 64c the air coil 28c arranged.

The Data Manager that handles a withdrawal 4 is at the trigger of the air coil 28c radially inward through the spindle 34c the underwater spool 30c guided and is the trigger inside the spindle 34c on and on the winding package 36c opposite side of the spindle 34c ,

The spindle 34c the underwater spool 30c forms part of the housing 48c the air coil 28c , on the inner surface of the unwinding data conductor 4 when pulling through the discharge opening 60c is guided along it. The housing 48c is an element that the air coil 28c surrounds radially outwardly and this completely encloses in the direction radially outward. The spindle 34c the underwater spool 30c surrounds the air coil 28c at its rear end, thus forming part of the housing 48c , By merging the spindle inner surface with a part of the housing inner surface, a particularly compact design can be achieved. In addition, parts and material and thus weight can be saved.

The spindle 34c is directly on a housing body of the housing 48c attached, the housing 48c also radially over the underwater coil 30c is led to their protection against external influences. The housing 48c So it is in the range of the spindle 34c divided into two parallel sections, which overlap radially: The inner parallel part forms the Gehäuseinnenwandung in the region of the discharge opening 60c and the spindle 34c , The outer area forms the vehicle housing and a radial overlap of the underwater coil 30c for protection to the outside.

The winding floor 52c the underwater spool 30c lies along its entire surface radially outside the winding bottom 64c the air coil 28c so that the diameter of the winding package 36c the underwater spool 30c is greater than at least the inner turns of the winding package 38c the air coil 28c , This allows a relatively large axial space, a large winding volume and thus a large length data conductor 4 be housed. It can also be out of the discharge opening 74 moving out data ladder 4 radially far from a cavity 68c spaced by which an engine jet for propulsion of the vehicle 2 while driving the vehicle 2 to be led.

The underwater spool 30c is in relation to the dispensing opening 60c arranged so that its spindle axially in the area of the narrowest point of the discharge opening 60c lies. As a result, the overall design is very compact. In particular, the spindle inner surface forms the outer wall of the dispensing opening 60c at their narrowest cross section.

The underwater spool 30c is partially axially behind the air-core coil 28c arranged, at least areas of the underwater coil 30c So are axially behind the air coil 28c arranged. In principle it is also possible to use the underwater coil 30c completely axially behind the air-core coil 28c to arrange, or alternatively in front of the air coil 28 allow to complete, so that the air coil 28c axially far backward than the underwater coil 30c ,

7 shows the rear part of the vehicle 2 , taking on the representation of the rudder 24 out 1 has been omitted for clarity. You can see the back part of the case 48c with the underwater coil arranged therein 30c , Their dispensing opening 74 forms the radially outermost region within the housing 48c the rear of the vehicle 2 , Out 7 is clearly good to see that the great radius of the underwater coil 30c a long data line 4 on the underwater spool 30c allowed at relatively flat construction of the winding package 36c the underwater spool 30c ,

Inside the dispensing opening 74 is in 7 the back of the spindle 34c the underwater spool 30c and a spindle 76 an intermediate coil 78 to see that radially inside the underwater coil 30c is arranged. Not shown is the winding package 36c the underwater spool 30c and an intermediate winding 80 , in the 6 indicated by dashed lines. The radially inside the intermediate coil 78 lying cavity 68c forms the passage for the engine jet of the vehicle during its flight.

8th shows a perspective view of the vehicle 2 from the rear looking forward in the direction of travel of the vehicle 2 , again turning to the presentation of the rudder 24 was waived. Visible - from outside to inside - is the housing 48c , the spindle 34c the underwater spool 30c , the dispensing opening 60c , the wrapping package 38c the air-core coil in front of the spindle 76 the intermediate coil 78 and the cavity 68 through which the engine jet during the flight of the vehicle 2 exit. Also shown is the transition section 42c of the data manager 4 , in the transition area of the underwater coil 30c to the intermediate coil 78 ,

The spindle 34c the underwater spool 30c is in 9 in a perspective side view without the housing 48c shown. You can see the winding bottom 52c , the front flange 66c , the only hinted winding package 36c the underwater spool 30c limited to the front, and the rear steering means 50c that's the wrapper 36c limited to the rear. How to 5 described, the steering means expands 50c on his to the winding package 36c facing side conically backwards with the cone angle α.

In this conical surface is a laying waste 70c introduced, which has a front groove area 82 and a rear groove area 84 having. The front groove area 82 is in the conical and forward facing inclined surface of the steering means 50c cut in, whereas the rear groove area 84 in the rearward facing surface of the steering means 50c is incorporated. In contrast to the embodiments of the 2 to 5 is the laying channel in this embodiment 70c So at the rear end of the winding package 36c arranged, ie in the steering means 50c ,

The data manager 4 is from the changing bottom 52c through the front groove area 82 the laying waste 70c and from there to the back area 84 the laying waste 70c guided to then in a straight line to the intermediate winding 80 to run, as in 8th is shown. He dives here by the steering means 50c without being guided by this particularly far radially outward, causing a wave formation of the data conductor 4 at his departure and thus a beating of the data manager 4 and its burden on the deduction can be kept low. In 9 is implied as the data manager 4 straight from the front groove area 82 the laying waste 70c is pulled out during a drainage.

The incision of the front groove section 82 in the steering means 50c is in 10 especially good to see. The valley bottom 86 is deeply cut in the steering means 50c and projects in the region of its maximum radial extent only slightly beyond the radial extent or the radius R _{1 of} the winding bottom 52c out. The maximum radial elevation of the valley bottom 86 or its maximum radius R ₂ protrudes less than 50% of the survey of the steering means 50c , in particular less than 1/3 of the collection of the steering means 50c over the spindle bottom 52c out, with both radii R ₁ , R ₂ from the axis of symmetry of the coil system 26c or the spindle 34c are measured. In this way, an extension of the data conductor 4 that by overcoming the steering means 50c possibly present, be kept low, whereby a wave formation is reduced in the trigger.

11 shows a section of the spindle 34c the underwater spool 30c from behind on the steering means 50c , The in 11 hidden valley bottom 86 is shown in a narrow dashed line. Dashed dashed is the spindle bottom 52c shown. As can be seen by the radii R ₂ , R ₁ , the valley bottom protrudes 86 only slightly radially over the spindle base 52c out. The valley bottom 86 is also radially curved at its output side and rear end in such a way that the data conductor 4 radially kink-free both in the front area 82 as well as in the back area 84 the laying waste 70c , as well as from the publisher 70c led out as in 11 is shown. Also in this way can a wave formation and a load of the data conductor 4 be reduced in a bend to be avoided.

How out 9 can be seen, the data conductor is dragging 4 during its withdrawal over the radially outermost edge 54c of the steering means 50c or the underwater coil 30c , This edge 54c is in the area of laying 70c notched and thus hinders deduction of the data conductor 4 because it grinds over this notch every turn. In order to minimize such obstruction, the circular outer edge is 54c of the steering means 50c through the laying waste 70c - From the rear to the front on the steering means 50c - only very slightly notched, as in 11 is shown. A little notch 88 still remains and is in 11 shown. However, its depth is less than 2 mm and it is also rounded tangentially on both sides and very flat on both sides - less than 30 ° on each side - executed. In this way, the loops of the data conductor 4 over the notch 88 only to a very small additional load of the data conductor 4 on withdrawal. The depth of the notch 88 is less than 10% of the elevation of the steering means 50c over the spindle bottom 52c the underwater spool 30c out.

Like from the 9 . 10 and 11 can be seen, the rear area runs 84 the laying waste 70c in tangential departure direction of the data conductor 4 axially to the rear. So he is guided edge-free to the rear, so that the laying 70c in their rear area 84 in principle, loses its groove shape and is configured to a wedge-shaped depression pointing with the wedge tip in the withdrawal direction. The man from the laying house 70c withdrawn data conductors 4 This allows it to be free from the rear area 84 swing out without bumping against an edge. To the data manager 4 not to damage the fast trigger, is the rearward facing area 84 designed with a significantly larger tangential width than the forward facing area 82 has an axial width. The tangential width of the laying channel 70c in the back area 84 in this case is at least ten times the diameter of the data line 4 in the area of the transitional section 42 ,

As the data manager 4 at the underwater discharge at the steering means 50c along dragging, and thus also on the laying waste 70c , should be the orientation of the front area 82 have a tangential component. The tangential component can be understood here as a directional component of the front region 82 in the tangential direction in a side view of the steering means 50c perpendicular from above, as in 9 shown. Conveniently, the angle β between the axial direction of the coil system 26c and the orientation of the front area 82 at least 45 °, in particular at least 60 °, with at least 75 ° have proven to be particularly advantageous.

To the about the embarrassment 70c In addition, it is advantageous if the laying channel is to protect the grinding, unwinding data conductor 70c at least partially, especially in the front area 82 , is covered. This can be done by a tear-off foil or another element. It is additionally or alternatively possible, the laying channel 70c or the front part 82 to at least partially fill it with a silicone or other substance.

In its further course becomes the data conductor 4 in through the underwater coil 30c to at the front to the air coil 28c guided. So it runs with its transition section in the unwound state of the winding package 36c the underwater spool 30c to the rear and through the rear edge 54c through radially inward. Later on, he is again led forward to pass through the delivery opening 60c through the winding package 36c the air coil 28c to reach.

To the exhaust transition from the underwater spool 30c to the air coil 28c To improve, the transition section on the intermediate coil 78 be wound up. The intermediate coil 78 contains, for example, only one single location, so the data manager 4 in the transitional trigger only once from back to front through the intermediate winding 80 is deducted. In the further course is the data manager 4 then to the air coil 28c guided.

12 shows the intermediate coil 78 or their spindle 76 in a perspective view. The in 12 not shown data conductor 4 is on the winding ground 90 the intermediate coil 78 wound up in his section of the underwater spool 30c to the air coil 28c from the back to the front. If he has the front flange 92 the spindle 76 he is in a misdemeanor 70d guided in the forward facing flange 92 is incorporated. This can be analogous to the flange 70b the underwater spool 34b be executed. At the in 12 illustrated embodiment, the laying channel runs 70d axially flat at its radially inward end so that the data conductor 4 at its wedge-shaped end, no edge has to pass to get into the laying hole 70d to get. Also at its radially outer end, the laying channel 70d be axially rounded in order to transition to the air coil 28c no edges to create.

How out 6 you can see, is the radius of the winding floor 90 the intermediate coil 78 smaller than the radius of the winding bottom 64c the air coil 28c , This applies expediently also analogously to the radial extent of the front flange 92 and the rear flange 94 the intermediate coil 78 , In this way, an air vent of the air coil 28c not disabled.

Through the intermediate coil 78 Transitions between the underwater coil 30c and the air coil 28c compensated or reduced so that the data manager 4 In this transition at the trigger smaller waves beats and thus less burden. In order to load the data conductor even with the intermediate trigger little, can be a front of the flange 94 be tapered towards the front, analogous to the steering means 50 ,

The data manager 4 should be from the air coil 28c to the underwater coil 30c seamless, that is without splicing, run. This requires that the data manager 4 in one piece on the air coil 28c and on the underwater spool 30c is wound. To achieve this, it is beneficial if the data conductor 4 when winding the coil system 26c first on the air coil 28c and then on the intermediate coil 78 is wound. This is the case 48c and the spindle 34c away.

Now it is beneficial if the underwater spindle 34c detached from the housing 48c is wound. For this it is suggested that the spindle 34c the underwater spool 30c is held in such a position with an auxiliary holder that its final mounting position relative to the air-core coil 28c at least substantially corresponds. Smaller position fluctuations in the range of a few millimeters can be tolerated under certain circumstances. After winding the underwater coil 30c can its spindle 34c on the housing 48c be attached, this case to the spindle 34c approximated and thus brought into its final position. Subsequently, the spindle 34c on the housing 48c attached and the auxiliary holder for holding the spindle 34c can be removed.
