Description

Decoy for torpedo defense}

The present invention relates to a toroy defense decoy.

Modern submarines are equipped with torpedo defense devices, and the torpedoes approaching the submarines can be deflected or destroyed depending on the configuration of the deed. To this end, the deck bodies are arranged transversely or obliquely to the longitudinal extension of the submarine, and are discharged from starter tubes arranged in the area of the upper deck of the submarine and / or the tower. After being ejected from the starter tube, the deceased persons estimating the suspended position reach a certain distance of the submarine and may change the diving depth of the decks in advance if a suitable drive is provided.

It is necessary to make the weight force of the deceased body roughly correspond to the weight force of the displaced water so as to estimate the floating position and stay therein. Therefore, the deceased body has a relatively low weight. Because of this low weight, deceivers only absorb a smaller amount of kinetic energy, so they are emitted only at a relatively short distance to the submarine.

It has been found that this relatively short-range discharge orbit attempts to safely move the submarine from a torpedo approaching the desired escape route of the submarine, apart from the discharge of the deceased, If not, it will collide with the deceased.

It is an object of the present invention to provide a dexter of the aforementioned type which can be discharged at a greater distance from a submarine without altering the remaining functional characteristics as compared to the prior art dexterities known hitherto.

The object of the present invention is achieved by a tamper-evident body having the characteristics described in claim 1. [ A more advantageous configuration of this degenerate entity can be understood from the dependent claims, the detailed description and the drawings. Therefore, features specified in the dependent claims according to the present invention can suggest a solution of the invention according to claim 1 by its constitution or combination.

The dexterous body according to the present invention includes a mass body that can be separated from the remaining deceased body. It can be understood that the remaining deceased body is a base body that is elongated and includes all the functional components of the deceased body, and the weight thereof necessarily corresponds to the weight of the water to be drained. The mass body is detachably fixed to the base body and forms an additional weight and is not a problem since the mass body can be detached from the base body in spite of initially deteriorating the suspension characteristics of the de- It may be discharged at a predetermined time in order to exhibit optimal suspension performance. However, the additional weight that the mass body caused by the mass body prior to discharge of the dexter body from the starter tube of the submarine improves the performance of the dexterous body according to the present invention, which increases the absorption of kinetic energy, Whereby the dexterous body according to the present invention can be discharged at a greater distance from the submarine under the same discharge condition. As a result, the risk of collision between a deck and a submarine during navigation of the submarine is significantly reduced. Advantageously, the submarine according to the invention can also be constructed on the basis of a de-embodied state according to the state of the art, so that the de-embodied body considered according to the state of the art forms the base body and the mass body is detachably fixed thereto.

Advantageously, an attempt is made to eject the mass body of the tamper-evident body only when the tamper-evident body is located at a suitable distance from the submarine. The device for releasing the mass body may be operated, for example, in a distance dependent manner (e.g., a rip cord of a parachute) to achieve this. However, in order to achieve this, a mass body which is detachable from a dehydrator, which is preferably maintained in a time-controlled manner, is designed. Therefore, the dexterous body according to the present invention can include a switch mechanism, and operates the mechanism for separating the mass body with a predetermined time delay after the dexterous body leaves the starter tube.

Basically, the mass body can be disposed at any position of the foundation body. Particularly advantageously, however, the mass body forms the head of the deceased. That is, the mass body is disposed at one end of the foundation body and is disposed at the front face in the discharge direction of the hand-held body. Advantageously, the mass body does not extend beyond the outer cross-sectional contour of the base body. The center of gravity of the dexter body is set as far as possible from the front face in the discharge direction of the dexterous body by the mass body forming the dexterity head and reaches a proper running state of the dexterous body particularly during the discharge movement. Moreover, the mass body forming the head of the tampering body may also form a protective cap for the functional units disposed at the end of the foundation body, which is located in the front face in the discharge direction.

In these functional units, for example, it may be the case of a sound device or a propeller arranged therein to change the depth of the dive. The hydrodynamic characteristics of this deformation body during the evacuation process may also be improved according to the proper external shape of the mass body.

The tamper-evident body may include an electronic control device for actuating a device for releasing the mass body for ejecting the mass body from the deaf-mute body. Such a control device has an advantage that it can be operated in a remote control manner. It should be noted, however, that electronic control is regarded as a battery for electricity supply of the control. Moreover, since electronic control tends to be significantly more problematic as compared to hydraulic or mechanical actuation controls, it is to be expected that the failure rate of these deceptive objects is considerably high by using an electronic control device for the deceit bodies. For this reason, a preferred solution is to make the mass body hydraulically and / or mechanically separable from the rest of the deck. In this context, the device for separating the mass body as well as the time or distance control for operating the device can be operated hydraulically and / or mechanically. Preferably, a mechanical or hydraulic spring mechanism is used as the time control.

Particularly preferably, the mass body is designed in such a manner that it can be separated into two portions in the transverse direction on the longitudinal axis of the dexterous body. Therefore, the mass body, which forms the head of the dexter body and is disposed so as to extend straight from the base body of the dexter body, can be separated into two parts in a plane lying on the vertical axis of the dexter body, It can be discharged in a simple manner to the side.

In accordance with the design of the two parts of the mass body forming the head of the tamper-evident body, the two parts of the mass body are separated from the head end of the mass body so as to hold the two parts of the mass body until they are separated And can be bonded in a positive and detachable manner in a positive fit. The shape coupling types are advantageously selected so that the two mass body portions can be separated from one another in a secure and fast manner. Thus, for example, at least one, preferably two, hooks arranged opposite one another can be formed in the end regions of each mass body portion, the end regions being spaced apart from the head end of the mass body, The hooks of the body portions are fitted and fitted together. In this state, the two mass body portions are fixed to each other at least transversely with respect to the longitudinal extension of the mass body, and the mass body portions may be separated from each other by a suitable relative movement between the mass body portions.

Typically, it may also be useful to couple two portions of the mass body to one another at the head end of the mass body. For this reason, a more advantageous design of the dexter according to the invention is to arrange the lock washers at the head end of the mass body, which locks together the two parts of the mass body. Therefore, at the head end of the mass body, the two parts of the mass body form portions that are joined together, for example, projections, which are elastically adapted to the shape lock or non-positive fit, . The lock washer by the elastic adaptation can be easily separated by the protrusion formed on the head end of the mass body to release the mass body from the remaining deformation bodies.

A compression spring, which is biased between the first and second portions of the mass body, is preferably provided to separate the two mass body portions from each other. The mass body is separated in the longitudinal direction of the tamper-evident body so that the operating direction of the compression spring is advantageously arranged in the transverse direction on the longitudinal axis of the dexter body or in the transverse direction on the partition surface of the mass body.

By virtue of the design of the dexter according to the invention, the lock washer simultaneously seats the mass body designed in a two-part manner at the head end of the deposed body, advantageously with the piston-cylinder arrangement, / RTI > In the piston-cylinder arrangement, the cylinder of the piston-cylinder arrangement, or a component which is movably coupled to the piston arrangement, advantageously moves the piston in a direction parallel to the intermediate axis of the lock washer, Can be disposed in one of the two portions of the mass body in such a manner as to fit the washer and separate the lock washers from the mass body.

In a typical piston-cylinder arrangement, the piston separates the interior of the cylinder into two cylinder chambers. Preferably, the biased compression spring is arranged in the second cylinder chamber at the rear in the direction of extension of the piston, while the first cylinder chamber is in the front face in the direction of extension of the piston and is filled with fluid, preferably glycol do. Thereby, the piston of the piston-cylinder arrangement may advantageously include a throttle bore, which forms an overflow connection of the first cylinder chamber of the piston-cylinder arrangement to the second cylinder chamber.

After actuation of the piston-cylinder arrangement, the compression spring disposed in the second cylinder chamber pushes the fluid lying in the first cylinder chamber into the piston, and the fluid slowly flows into the second cylinder chamber through the throttling hole. Therefore, the piston movement works slowly. Due to the proper travel path of the piston, the time control for removing the lock washer from the mass body and releasing the mass body from the remaining dexterity resulting therefrom can be realized.

Advantageously, the mass body ensures that it is not discharged from the storage position of the dexterature within the starter tube of the submarine. To this end, a lever mechanism for locking the piston of the piston-cylinder arrangement at the locking position in a form-fitting manner has been devised. This lever mechanism in the simplest case can form a single lever and can be pivoted from the locked position of the piston to the released position of the piston. However, this lever mechanism is preferred, whereby the lever is coupled to the lock element and is pivoted to the locked position of the piston or the released position of the piston. Particularly advantageously, the lever mechanism is designed in such a manner that the piston automatically releases after the diaphragm has moved away from the starter tube.

For this purpose, the lever of the lever mechanism can be advantageously operated by the compression spring. In this context, a design in which the lever is supported on a biased compression spring is preferred. Thus, when the tamper-evident body is disposed in the starter tube, the lever is disposed on a part of the mass body in such a manner that the lever is disposed on the inner wall of the starter tube or on the guide rail of the tamper- . As soon as the tamper-evident body is removed from the starter tube, the lever contact with the inner wall of the starter tube or with the guide rails disposed at the ends of the starter tube, and the spring by the compression spring can move to a position releasing the piston of the piston- .

The torpedo defense implements according to the present invention have the advantage of providing a dexterity which can be discharged at a greater distance from the submarine under the same discharge conditions without changing the functional characteristics as compared with conventional dealing bodies.

As a result, the risk of collision between a deck and a submarine during navigation of the submarine is significantly reduced.

The tamper-evident body may include an electronic control device for actuating a device for releasing the mass body to eject the mass body from the deaf-mute body. However, electronic control tends to be significantly more troublesome as compared to hydraulic or mechanical actuation controls. Therefore, in order to operate the device, a time control or a distance control method is used, and the device for separating the mass body is operated hydraulically and / or mechanically so as to solve the existing problems.

BRIEF DESCRIPTION OF THE DRAWINGS The invention will be described in more detail with reference to a preferred embodiment shown in the drawings.

The decoy 2 is shown in the starter tube 4 of the submarine in Fig. The vent hole of the starter tube 4 can be opened and closed by a pressure-resistant cover 6 so that the plug body 2 can be dry-stored in the starter tube 4. The cover 6 can be pivoted about the pivot axis B from the closed position of the exhaust hole to the open position of the exhaust hole. The guide rails 8 fixed on the inner wall of the starter tube 4 are affected by the storage of the engaging body 2 in the starter tube 4. [

As shown in Figs. 2 and 3, the hand-held body 2 includes a base body 10. This basic body 10 includes all of the essential functional units of the hand-held body 2. The mass body 12 forms the head of the immobilizing body 2 at the end of the foundation body 10 and is located at the front face in the discharge direction of the immobilizing body 2, As shown in Fig. The mass body 12 is detachable from the base body 10, which will be described in more detail below.

In the case of such a dexter 2 in which the diving depth can be changed after completion of the discharging operation of the dexter body 2 and separation of the mass body 12 from the basic body 10 . To this end, the base body 10 includes a propeller 14. The propeller 14 is disposed at the apex of a parabolic curved distal end 16 of the basic body 10 and the curved distal end 16 is adjacent to the cover 6, 18. The curved tip portion 16 has an outer surface slightly smaller than the cylinder portion 18 and forms an annular shoulder 20 in this state.

The mass body 12 is designed to be partially hollow and forms a cap that completely surrounds the curved tip 16 of the base body 10 and forms a cap in this area in the area of the propeller 14 and curved tip 16 Covers the other functional units of the deployed handler body 2, and protects the units in this way. The mass body 12 is designed in the form of a parabolic curve and the mass body 12 is merged into the cylinder portion 18 and the outer diameter of the mass body 12 Corresponds to the outer diameter of the cylinder portion 18 of the basic body 10.

The mass body 12 is always separated into two portions 22 and 24 in the longitudinal axis C direction of the hand-held body 2. In the region where the base body 10 is in contact with the cylinder portion 18, The protrusions 26 and the protrusions 28 are formed on the first portion 22 of the mass body 12 while the recesses 30 and the protrusions 32 are formed on the second portion 24 of the foundation body 10 The protruding portion 28 of the first portion 22 is formed in the recessed portion 22 of the second portion 24 in the state where the first and second portions 22 and 24 of the mass body 12 are assembled, The protruding portion 32 of the second portion 24 protrudes into the recessed portion 26 of the first portion 22. In this manner, the first portion 22 of the mass body 12 And the second portions 22 and 24 are releasably fixed to each other by being shaped in the transverse direction in a longitudinal direction C of the hand-held body 2.

An annular shoulder 34 forming a protrusion 36 on the mass body 12 is machined outwardly in the end region of the mass body 12 away from the base body 10. [ A lock washer 38 connecting the first and second portions 22 and 24 of the mass body 12 to each other in form-fitting and non-positive fit is mounted around the projection 36 do.

The first and second portions 22 and 24 of the mass body 12 are designed in a fixed manner to the parabolic curved tip of the mass body 12. The openings 40 are designed in this region of the first portion 22 of the mass body 12 so that the grooves formed in the mass body 12 from the outside of the first portion 22 extend to the longitudinal axis C). The opening 40 extending from the outside of the first portion 22 includes a section 42 which is shaped like a shoulder and expands to the cylinder portion 44.

The cylinder portion 44 of the bore 40 defines a cylinder 44 of the piston-cylinder arrangement with a piston 46 movably mounted on the cylinder 44. The piston 46 separates the cylinder into a first cylinder chamber 48 and a second cylinder chamber 50. The second cylinder chamber 50 is closed by a bushing 52 located at its end remote from the section 42 of the opening 40 and is connected to a piston rod 54 which faces the base body 10 through the opening 40, The bushing of the section of the guide is guided. An annular groove (55) is formed in the end region on this section of the piston rod (54).

A threaded bushing 56 is screwed into the section 42 of the aperture 40. Another section of the piston rod 54 which is directed toward the head end of the body is guided through the thread bushing 56. This section of the piston rod 54 may move relative to the lock washer 38 so that the lock washer 38 may be released by the projection 36 of the mass body 12. [ A threaded spring (58) supported between the piston (46) and the bushing (52) is supported in the cylinder chamber (50). The bushing 52 is fixed at its original position by a setscrew 53. Fig. The cylinder chamber 48 is filled with glycol. The glycol may flow from the cylinder chamber 48 into the cylinder chamber 50 through a throttle bore 50 formed on the piston 46.

A groove-shaped recess 62 is formed in the region of the cylinder portion of the mass body 12 on the outer side of the first portion 22 of the mass body 12. The lever 64 is mounted on the groove 62 so as to be rotatable about the axis D. The lever 64 in the storage position of the hand-held body 2 in the starter tube 4 is supported on one of the guide rails 8.

A compression spring 66 which is mounted on the first portion 22 on the longitudinal axis C of the hand-held body 2 and arranged in the transverse direction and which fits in the corresponding groove on the lever 64, do.

The actuation rod 68 operates at the lever 64 and its end and is located proximate the head end of the mass body 12. [ The operating rod 68 is guided movably in the first portion 22 of the mass body 12 to the longitudinal axis C of the hand-held body 2 in the normal 90 degrees and a hook 70 Which fits into the annular groove 55 formed on the piston rod 54 on the side remote from the lever 64 and in this way keeps the piston 46 of the piston-cylinder arrangement in the locked position.

The pocket hole 72 is formed in the second portion 24 of the mass body 12 adjacent to the first portion 22 and extends from the longitudinal direction of the second portion 24, Lt; RTI ID = 0.0 > 90 C. < / RTI > The pocket holes 72 are formed in a pressure-biased manner on the first portion 22 of the mass body 12 when the portions 22 and 24 of the mass body 12 join together To receive the threaded springs 74 that are supported.

The manner of operation of the hand-held body 2 according to the present invention is described as follows.

The levers 64 are supported on the guide rails disposed on the inner wall of the starter tube 4 so that the operating rod The hook 70 of the piston rod 68 is fitted in the annular groove 55 formed in the piston rod 54 to prevent the piston 46 of the piston-cylinder arrangement from moving. At the same time, the projection 76 disposed at the end of the lever 64, which is remote from the articulation of the actuating rod 68, is disposed on the curved tip 16 of the base body 10, To place the functional units in a non-operating position by applying a pressure to the actuating element 78 which actuates the functional units disposed in the housing.

The engagement between the guide rail 8 and the lever 64 is released and the compression spring 66 makes the lever 64 pivotable in one position, The hook 70 formed in the actuating rod 68 releases the piston rod 54 while the protrusion 76 moves away from the actuating element 78 disposed on the basic body 10, (78) is moved to a position for operating the functional units located in the foundation body (10).

At the same time, a threaded spring 58 disposed in the cylinder chamber 50 can move the piston 46 of the piston-cylinder arrangement in the direction of the cylinder chamber 48, wherein the glycol placed in the cylinder chamber 48, This movement is effected in a delayed manner since the gas flows slowly from the cylinder chamber 48 to the cylinder chamber 50 through a relatively small cross section of the throttle bore 60.

After a predetermined time, the immobile body 2 itself is already far away from the starter tube 4 or the submarine, and the piston rod 54 is in contact with the lock washer 38 and is formed on the head end of the mass body 12 By releasing it from the projection 36, the engagement of the first and second portions 22 and 24 of the mass body 12 is released at the head end.

As a result, the threaded spring 74 can push out the portions 22 and 24 of the mass body 12 so that they are separated from each other, and the two portions 22 and 24, in each case, Is pivoted outwardly around the pivot axis which is placed on the annular shoulder 20 opposite to each other, that is, it is rotated off the longitudinal axis C of the hand-held body 2.

Due to this rotational movement of the portions 22 and 24, the hook engagement at the end region of the mass body 12 away from the head end is released such that the coupling between the portions 22 and 24 is no longer present The portions 22 and 24, or the complete mass body 12 may be released from the base body 10.
