Description

[0001] WEAPON EJECTION DEVICE COMPRISING A PUSH CHAIN [0002]

The present invention relates to an apparatus for emitting an inorganic matter, in particular a mine, from an inorganic tube.

In the context of the present invention, the weapon is in particular a torpedo, a missile, a human body or a mine. These weapons are often carried by warships such as Corvette, frigates, destroyers, cruisers or submarines. This weapon is also customary for other types of emissions, but is often released by inorganic tubes.

There are many different types of inorganic tubes, especially with regard to the art of releasing weapons. Weapons are often released by pressurized air. In this way, weapons such as torpedoes can be released relatively quickly and easily. High acceleration is also possible here, which is necessary to accelerate a relatively heavy torpedo over its short-stretch inorganic tube to its release speed. The disadvantage is that this method is relatively loud. This can be tolerated when launching a torpedo in normal combat situations, as the released torpedo due to the relatively fast turn speed of the screw already indicates the release position.

There is also an inorganic tube that does not have a system for active release of the weapon. The weapon runs out of such a weapon tube, i.e. the weapon leaves the weapon tube by its own propulsion and by its own force. For example, a torpedo can run out from a weapon tube.

However, there are situations in which weapons must be released from weapon tubes where silent release is advantageous or an available release system is not available. For example, mines generally do not have their own propulsion, so mines can not be released from weapon tubes designed for self-running torpedoes.

The problem to be solved by the present invention is to create an inorganic emitting device that can be introduced into and removed from an existing inorganic tube for the release of at least one inorganic.

The above object is solved by an inorganic emission device having the features of claim 1. Advantageous modifications will become apparent from the dependent claims as well as the following description.

The apparatus for releasing an inorganic material according to the present invention can be introduced into an inorganic tube. The weapon releasing device comprises at least one first push chain and at least one first push chain magazine. The at least one first push chain may extend along the length of the inorganic tube from the at least one first push chain magazine of the weapon discharge device.

Push chains are known in the prior art, such as DE 20 2011 013 357 A1 and the documents cited therein. The advantage of a push chain is that it exhibits rigidity when it is moved in a linear direction due to its structure with a shape-fit interlocking link, but thanks to the joint there is a possibility of movement in the direction of rotation. Thus, the push chain is a bending-stiff chain, which exhibits stiffness under thrust loads, but is flexible and deflectable under tensile loads in one direction. Thus, thanks to the use of a push chain, an advantage is obtained in contrast to a rod or shaft requiring space behind the weapon for the entire length of the path through which the weapon must travel. Likewise, this system is advantageous in contrast to a retractable system, because the length and the retractable system for such a weight are very large and very well broken. Toothed belts or link chains are also unavailable because the necessary stabilization is nearly impossible and there is a very large loss of force due to friction.

The advantage of the present invention is that it is a compact design, which allows the design of the weapon release device to be introduced as an entirely self-contained component in the inorganic tube. The use of a push chain, on the other hand, allows the push chain to be stored in a compactly rolled-up state inside the weapon discharge device in the magazine of the push chain. Roll-up capability in one direction of the push chain is utilized for this. At the same time, the push chain can extend from the weapon release device. To this end, the push chain exhibits rigidity and extends outwardly of the inorganic tube from the forward end of the inorganic tube in the direction of the front skin. Weapons can be released.

Preferably, the weapon release device is freely movable within the inorganic tube along the longitudinal direction of the inorganic tube. The weapon release device preferably does not include a fixed connection to the inorganic tube, and in particular the weapon release device itself is not welded, threaded, or permanently connected to the inorganic tube. However, for example, the anchoring connected to the push chain may be removably connected to the portion of the inorganic tube.

As used herein, "rear" or "forward" refers to the direction of discharge of the weapons. Thus, "forward" is the direction in which the weapon leaves the weapon tube in each case in the application. Generally, this is the direction away from the vessel. Thus, "rear" is the interior of the vessel in the case of a submarine having, for example, an inorganic tube. This relationship does not indicate anything about the orientation of the inorganic tube relative to the direction of movement of the vessel.

In one embodiment, the weapon release device may be used to cause the push chain to extend from the weapon release device against the weapon to expel the weapon from the weapon tube. In an alternative embodiment, the weapon release device may be used to extend from the weapon release device against the bottom cover, wherein the push chain isolates the inorganic tube against the interior of the vessel. In this manner, the entire weapon release device moves through the weapon tube, and as a result, the weapon release device releases the weapon from the weapon tube.

Here and below, the release of the weapon does not only mean the release of a single weapon. Since the inorganic tube generally has a length of about 6 m to 10 m, the inorganic tube can accommodate torpedoes or missiles, often having a length of 5 m to 8 m. However, smaller, shorter weapons such as mines also exist. And, it preferably has the same outer diameter, such as 53 inches (21 inches), but has a length of only about 1.5 m to 3.5 m. Therefore, it is possible to load, for example, two, three or four mines in the inorganic tube next to the weapon-emitting device. In this case, the weapon-releasing device emits a back-end mine, which pushes the mines located in front of it and delivers them out of the weapon tube.

If the push chain extends against the bottom cover, the push chain would preferably include anchoring at its ends. The anchoring can be particularly configured in a V-shape or a curved shape. The anchoring ensures that the push chain can be held against the bottom cover or the inorganic tube on the one hand so that the weapon release device can move away from the bottom cover during the extension. On the other hand, the anchoring causes the push chain to remain anchored to the bottom cover at retraction, pulling the weapon release device again in the direction of the bottom cover.

If the push chain is extended against the weapon, the push chain would preferably include a coupling at its end, and a coupling may be made between the push chain and the weapon by the coupling. In one possible embodiment, the coupling is designed such that the weapon can engage the coupling from above. The advantage of this design is that, when using a bottom mine, the bottom mine sinks due to its high specific gravity, so that the bottom mine will be spontaneously released from the coupling during release. In this way, the front end may initially slant and the rear end may be slightly inclined to release from the coupling. In another possible embodiment, the coupling is designed such that the coupling has an opening mechanism. The opening mechanism may be released, for example, when the push chain is fully extended. The opening mechanism may also be released when the weapon forces against the coupling, for example in the case of a floating mine, when the floating mine exerts a force on the coupling by buoyancy.

In one embodiment of the present invention, the inorganic emission device comprises a first module and a second module. The first module includes a first push chain magazine, and the second module includes a second push chain magazine. The first push chain can extend from the first push chain magazine and the second push chain can extend from the second push chain magazine.

The modular design has two very large advantages. On the other hand, the two modules are individually smaller than the weapon-emitting devices made in a single piece. In this way, it is easier to maneuver two modules, especially within the confined interior of a submarine, than a single-piece device. On the other hand, thanks to the construction as two modules, the weight can also be distributed, thus making it easier to transport the module by the person. Another important advantage is that, thanks to the use of two push chains, the two push chains need to extend only half the distance in each case. Thus, when both push chains are extended at the same time and two push chains are given the same release time, they only need to be extended to half of the speed. Thanks to this speed reduction, the noise generated is reduced and therefore the acoustic signature is also reduced.

In a preferred embodiment of the present invention, the first module may be connected to the second module. The first push chain and the second push chain may extend in opposite directions along the longitudinal direction of the inorganic tube. The advantage of this arrangement is that the two modules can be placed back to back, for example. In this manner, the weapon release device is moved by one push chain away from the bottom cover, while the other push chain releases the weapon. Thanks to this arrangement, the two modules can interact better.

In another preferred embodiment of the present invention, the first module comprises a motor and a first gear wheel, and the second module comprises a second gear wheel. The motor drives the first gear wheel, and the first gear wheel drives the second gear wheel. This is an example of how two modules can interact. Because of this interaction, only one module needs to have a motor. In this way, the total weight and overall size of the weapon discharge device can be reduced. The use of two gear wheels is particularly advantageous when they have the same size. In this way, since the two modules need to release the push chains in opposite directions each time, in addition to the transmission of the drive, the direction of rotation is reversed at the same time.

In another preferred embodiment of the present invention, the first gear wheel drives the first push chain and the second gear wheel drives the second push chain. By virtue of this embodiment, the number of movable elements can be minimized, and therefore noise emissions can be minimized.

In an alternative embodiment of the present invention, the first push chain and the second push chain may extend in the same directions along the longitudinal direction of the inorganic tube. Preferably, one module is disposed on the bottom cover, and one push chain drives the second module. The second module releases the weapon to another push chain. An advantage of this embodiment is that only one module needs to be moved during the inorganic release. Thus, the total moving mass can be reduced.

Similarly, when the push chains move in opposite directions, one module is placed on the bottom cover, one module is placed on the weapon, and two modules are moved between the modules, It can be considered to be disposed. Similarly, it is conceivable that when the push chains move in the same direction, the two modules extend the push chains in the direction of the bottom cover.

In another embodiment of the present invention, the first module and the second module each have a maximum length of 1.2 m in the longitudinal direction and a maximum weight of 50 kg, respectively. Particularly preferably, the first module and the second module each have a maximum length of 1 m in the longitudinal direction and a maximum weight of 45 kg, respectively. In this way, the individual modules can be moved by only two persons, respectively, and can be operated very easily even within the limited internal space of the submarine. Further optional components of these modules may be removed to reduce the weight of the module. For example, the motor may be removable from the module.

In another embodiment of the present invention, the weapon releasing device comprises a motor, and the motor is driven hydraulically or electrically. Particularly preferably, the motor is driven hydraulically. Hydraulic drive has many advantages. When the weapon is released, the inside of the inorganic tube is submerged. In this way, the hydraulic motor can be very compact and integrated into a space-saving design. Vessels, especially submarines, already have standards applied to many hydraulically driven systems, so no additional infrastructure is needed to provide the required energy. For example, the motor may be electrically operated, but in this case it must have an adequate and reliable insulation for the surrounding seawater.

In another embodiment of the present invention, the weapon releasing device comprises a drum for holding a power supply line. This embodiment is particularly preferred when the weapon release device is composed of two modules, such as a back-to-back arrangement. In this case, the motor needs to be supplied with energy, and the distance from the inside of the inorganic tube to the receptacle is changed by the extension of the push chain. To this end, a power supply line, such as a hydraulic line or an electric line, that supplies power to the weapon discharge device is provided or taken by the drum.

In another embodiment of the present invention, the inorganic emission device includes a horizontal stabilizing portion, and the horizontal stabilizing portion is designed to contact both the inorganic tube and the lateral guide rails on the lateral guide rails disposed in the inorganic tube.

The inorganic tubes often have four guide rails and the weapons discharged from the inorganic tubes by the guide rails are stabilized and guided. In this case, the upper guide rail often has a groove for receiving a retaining boss, whereby the weapon having the retaining boss can be secured within the inorganic tube against movement along the length of the inorganic tube . To hold the weapon against other movements and also to hold it fixed under impact loads, the inorganic tube usually also has two lateral guide rails and one bottom guide rail.

In another embodiment of the present invention, the weapon emitting device includes a device for detecting the position of the emitting device. The device for detecting the position of the emitting device may comprise, for example, one or more sensors in the tube for positioning. Alternatively, the device for detecting the position of the discharge device may have a step counter on the gear wheel, for example.

In another embodiment of the present invention, the weapon release device may extend one or two push chains having a travel speed of less than 0.5 m / s at a constant speed.

In another aspect, the present invention is directed to a system comprised of two to four bottom mines, as well as an inorganic release device according to the present invention. This system can be operated like a heavyweight torpedo. The advantage of such a system is that it can be quickly removed from the inorganic tube after the release of the bottom mine by the weapon releasing device and a new system consisting of two to four bottom mines, It can be loaded. In this way, a number of bottom mines can be placed relatively quickly.

In another aspect, the invention relates to an inorganic tube and a submarine having an inorganic release device according to the present invention disposed in the inorganic tube.

In another embodiment of the invention, the submarine comprises an inorganic tube, an external skin, and a prelaunch section disposed between the inorganic tube and the outer skin. With the weapon discharge device according to the invention, the bottom mines can be released from the inorganic tubes. The weapon tube comprises an upper guide rail, a lower guide rail and two lateral guide rails, the foot pre-section comprising an upper guide rail of the foot pre-section, a lower guide rail of the foot pre-section, Guide rails. The upper guide rail of the foot pre-section has an upwardly directed swivel in the area of the outer skin. The advantage of this submarine is that it can easily decouple the bottom mine from the push chain releasing the bottom mine. Once the bottom mine has been released and has already partially reached the free water in front of the submarine, the bottom mine will sink forward due to gravity, so that the rear end can be lifted and released from the push chain have.

The present invention is described in more detail below with reference to a particularly preferred embodiment shown in the drawings.

1 is a schematic cross-sectional view of two inorganic tubes having two inorganic emitting devices.
2 is a schematic sectional view of an inorganic emission apparatus.
3 is a view of the inside of the inorganic tube having the inorganic discharge mechanism as viewed from the bottom cover.

1 is a schematic cross-sectional view of two inorganic tubes 30 on which the other is located. For simplicity, for example, a muffle valve and an outer skin valve are not shown. There is an individual inorganic emission apparatus 10 in both of the inorganic tubes 30. In the upper side inorganic tube 30, the inorganic emitting device 10 is in a stowed position. At the side of the weapon releasing device 10, there are three bottom mines 40 in the inorganic tube. In the lower inorganic tube 30, the weapon releasing device 10 has already released the lower mine 40, and the rearmost bottom mine 40 has just left the inorganic tube 30 and sinks toward the seabed. The weapon releasing device 10 is composed of a front module 20 and a rear module 22. The front push chain 50 can be extended from the front module 20 by the front push rod 51 and the rear push chain 52 can be extended from the rear module 22 by the rear push rod 53 have. In order to extend the push chains 50 and 52, the weapon emitting device 10 has a motor 60, which is actuated by a power supply line 66 (see FIG. 2). The power supply line 66 may be taken by the drum 62. The front module 20 includes a motor 60 and the rear module 22 includes a drum 62 having a power supply line 66 as depicted. In this way, an optimal weight distribution of the modules can be obtained, so that the two modules 20, 22 can be easily removed from the inorganic tube 30 by two persons each time.

A foot pre-section is disposed between the inorganic tube (30) and the outer skin (70). Within the inorganic tube are an upper guide rail 92, two lateral guide rails 90, and a bottom guide rail 94. These guide rails also continue in the foot pre-section as the upper guide rail 112 of the foot pre-section, the lateral guide rails 110 of the foot pre-section and the bottom guide rail 114 of the foot pre-section. The upper guide rail (112) of the foot pre-section has an upwardly directed swivel on the side facing the outer skin (70). As can be seen from the bottom mine 40 in the lower inorganic tube 30, this upward directed swivel tilts downward due to its high specific gravity after the bottom mine 40 leaves the ship and is lifted slightly at the rear end , Causing the lower mine 40 to be released from the coupling 54. In this way, the bottom mine 40 is released from the coupling 54 of the front push chain 51.

At the end facing the bottom cover 32, the rear push chain 52 has a rear push rod 53 and the rear push rod 53 has an anchoring 56. The anchoring 56 serves to hold the rear push chain 52 on the one hand when the rear push chain 52 extends and pushes the weapon release device 10 through the inorganic tube 30. On the other hand, the anchoring 56 keeps the end of the rear push chain 52 in place when the rear push chain is retracted once again. In this way, when the rear push chain (52) is retracted, the weapon releasing device (10) is retracted in the direction of the bottom cover (32).

The front module 20 and the rear module 22 are mounted on the inner side of the inner weapon tube 35 on the lateral guide rail 90, as can be seen more clearly in Figure 3. [ And a horizontal stabilizing portion 100 which is in contact with the wall of the horizontal stabilizing portion 100.

Figure 2 shows the weapon release device 10 at a greater rate. Likewise, it is apparent that the inorganic tube 30 shown here is composed of the inner inorganic tube 34 and the outer inorganic tube 36. This design is such that there is only a very small gap between the torpedo and the wall 35 of the inner weapon tube corresponding to the thickness of the guide rails 90, Particularly advantageous. As a consequence, if additional weapons, such as mines, are to be released, in fact a further component can not be introduced into the inner weapon tube 34, in a particularly preferred embodiment shown here as an example, the weapon release device 10 according to the invention It is necessary to use.

It is clearly recognized that the front push chain 50 can be spirally mounted on the front module 20 at the front push chain magazine 24. [ This is due to the fact that the push chain is stiff in the other direction so that the push chain can be deflected in only one direction. Thus, the rear push chain 52 can be spirally mounted to the rear module 22 from the rear push chain magazine 26. [

The motor 60, which is preferably a hydraulic drive type, drives the gear ring 64. [ The gearing 64 is connected to the propulsion gearing of the push chain 120 via a chain or serrated belt. The push chain gearing 120 of the push chain is two-part and includes a forward gear wheel 122 and a rear gear wheel 124. Thanks to these gear wheels 122, 124, the synchronous ejection of the push chains 50, 52 on the one hand can be ensured. On the other hand, this simple design guarantees the reversal of the direction of drive between the front module 20 and the rear module 22.

Moreover, it is clearly seen in Figure 2 how the power supply line 66 can be taken by or provided by the drum 62. The power supply line 66 extends to the connection in the inorganic tube 30, which is not shown for reasons of clarity. Moreover, the anchoring 56 is clearly recognized. This joins over the inner inorganic tube (34) in the outer inorganic tube (36) and thus allows the necessary fixing. The connection of the coupling 54 to the coupling 54 and the bottom mine 40 is also clearly shown. The bottom mine 40 is placed in the coupling 54 from above.

3 shows the weapon discharge device from the perspective of the bottom cover 32 and can recognize the bottom mine 40 in the background. On the other hand, the anchoring 56 is apparent, which fixes the rear push chain 52 at the rear end of the inorganic tube 30. The anchoring 56 engages the outer inorganic tube 36 and lies against the wall 37 of the outer inorganic tube. The shape in this example is curved, but it may be V-shaped. The upper guide rail 92 has a groove. This generally serves to accommodate the retaining boss of the torpedo. It is also preferable that the inorganic emission apparatus 10 is coupled to this groove of the upper guide rail 92 for stabilization. And, the inorganic release device 10 is stabilized by the horizontal stabilizer 100, and the horizontal stabilizer may have the slides 102 at the ends. They are placed against the lateral guide rails 92 and hug the wall of the inner inorganic tube 35. In this way, it is possible to stabilize the weapon releasing device 10 without having to install an additional device in the inorganic tube 30. [

In order to connect the rear module 22 to the front module 20 (not visible in Fig. 3), it is desirable to provide a connection element 130 that can be removed for separation of the modules 20,22.
