Description

The apparatus of speed reduction for torpedo launch test}

The present invention relates to a speed damping device for a torpedo launch test. More specifically, it relates to a speed damping device required for a land launch test device for torpedo launchers including forced launch and self-propelled launchers.

In general, combat submarines are equipped with weapons such as torpedoes, missiles, and mines for attacking enemy ships or enemy submarines, and are launched by various launch systems.

The weapon launch method can be largely divided into a swim out method that leaves the launch tube with the propulsion of the weapon itself and a positive discharge method that pushes the weapon from a submarine. Among them, the forced firing method is divided into direct air, water ram system, and air turbine pump system.

In order to launch weapons from such a launch system, it is necessary to inspect and test whether the weapon system is properly equipped. Conventionally, in order to launch a launch test for an armament (eg, torpedo) in a launch system, a floating vehicle having a torpedo launch tube and related structures is lowered to the surface of the water to perform a launch test in an open water environment or a launch test in an actual submarine.

Advantages and features of the present invention, and methods of achieving them, will become clear with reference to the detailed description of the following embodiments taken in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various different forms, and only these embodiments make the disclosure of the present invention complete, and those skilled in the art are provided to fully inform the scope of the invention, and the present invention is only defined by the scope of the claims.

Terminology used in this specification is for describing the embodiments, and is not intended to limit the present invention. In this specification, singular forms also include plural forms unless specifically stated otherwise in a phrase. As used herein, “comprises” and/or “comprising” does not preclude the presence or addition of one or more other components, steps, operations, and/or elements in which a stated component, step, operation, and/or element is present.

Unless otherwise defined, all terms (including technical and scientific terms) used in this specification may be used in a meaning commonly understood by those of ordinary skill in the art to which the present invention belongs. In addition, terms defined in commonly used dictionaries are not interpreted ideally or excessively unless explicitly specifically defined.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the present invention will be described in more detail. The same reference numerals are used for the same components in the drawings, and redundant descriptions of the same components are omitted.

The purpose of the torpedo launch test device is to measure the launch speed of a torpedo when the rear end of the torpedo passes through the foremost part of the torpedo tube, using the propulsive power provided by the torpedo tube or the propulsive power of the torpedo itself. At this time, in order to retrieve the accelerated torpedo, the deceleration section of the torpedo being propelled is required, and in the sea test, a certain space is placed in front of the torpedo tube to induce natural deceleration of the torpedo. However, when installing a torpedo launch test device on land, it is easy to perform a torpedo launch test, but it is difficult to have a long deceleration section like in a sea test, and the cost of facility expansion increases as the additional deceleration section is increased.

Conventionally, for a torpedo launch test, a torpedo launch test was performed in an open water environment by lowering a floating vehicle having a torpedo tube and related structures installed thereon, or a torpedo launch test was performed in an actual submarine. This is not easy to repeat tests, and there is a risk of having to mount unverified armaments on submarines. Therefore, there is a need for a land torpedo launch test apparatus for facilitating repetitive torpedo launch tests and facilitating product development and performance verification. However, as described above, when installing a torpedo launch test device on land, it is easy to test, but it is difficult to have a long deceleration period like in a sea test, and the cost of facility expansion increases as the additional deceleration period increases. Therefore, it is advantageous to have a minimum deceleration period.

According to the present invention, in order to solve such conventional problems, an efficient and reasonable land torpedo launch test device can be implemented by providing a speed reduction device in a land torpedo launch test device to reduce the length of a deceleration section of a torpedo being propelled.

The speed damping device according to the present invention converts the kinetic energy of a torpedo being propelled into a spring force by using the elasticity of an elastic means such as a spring, and generates a force in the opposite direction to the motion of the torpedo being propelled, thereby reducing the speed of the torpedo.

Elastic means such as a spring spring can be implemented as a component such as a tape measure used in daily life, and since it has a force to return a belt shape to the body, it can generate force in the direction opposite to the direction of propulsion of the torpedo.

1 and 2 are diagrams schematically showing a conventional torpedo launch test device.

Referring to FIG. 1 , a conventional torpedo launch test device includes a water tank 10, a torpedo tube 20, a torpedo 30, and a rail R.

The water tank 10 may be filled with water, for example, and may have the same environment as an underwater environment in which the torpedo 30 mounted on a submarine is launched. The water tank 10 is prepared for the test, and in order to use the torpedo 30 in actual combat, the test and verification must be performed in an underwater environment.

The torpedo 30 is a self-propelled torpedo. The torpedo 30 may leave the torpedo tube 20 with its own propulsion.

The torpedo tube 20 is a passage through which the torpedo 30 is passed by launching the torpedo 30, and a torpedo launch speed measurement point P is provided at the front of the torpedo tube 20, and can be used for a torpedo launch test. The torpedo tube 20 may be a passage connecting the inside of the submarine and open water.

The rail R is a path through which the launched torpedo 30 is propelled outside the torpedo tube 20, and since the rail R is in an underwater environment, the speed of the torpedo 30 being propelled can be reduced according to the resistance of water. Since the torpedo deceleration section (A) is relatively long, the length of the rail (R) also needs to be secured relatively long. In this way, if the length of the rail R is increased, not only the equipment cost increases, but also the space occupied by the test site becomes wider.

Referring to FIG. 2 , a conventional torpedo launch test device includes a water tank 10, a torpedo tube 20, a torpedo 30, a forced injection device 40, and a rail R.

The water tank 10 may be filled with water, for example, and may have the same environment as an underwater environment in which the torpedo 30 mounted on a submarine is launched.

The torpedo 30 is a forced launch torpedo. The torpedo 30 does not have its own propulsive force, and the torpedo 30 can leave the torpedo tube 20 with the force pushing the torpedo 30 through the forced ejection device 40. That is, FIGS. 1 and 2 show torpedo launch test devices in self-propelled and forced launch methods, respectively.

The torpedo tube 20 is a passage through which the torpedo 30 is passed by launching the torpedo 30, and a torpedo launch speed measurement point P is provided at the front of the torpedo tube 20, and can be used for a torpedo launch test. The torpedo tube 20 may be a passage connecting the inside of the submarine and open water.

The rail R is a path through which the launched torpedo 30 is propelled outside the torpedo tube 20, and since the rail R is in an underwater environment, the speed of the torpedo 30 being propelled can be reduced according to the resistance of water. Since the torpedo deceleration section (A) is relatively long, the length of the rail (R) also needs to be secured relatively long.

Hereinafter, embodiments according to the present invention will be described with reference to the drawings.

3 is a diagram schematically showing a torpedo launch test apparatus according to an embodiment of the present invention.

Referring to FIG. 3, the torpedo launch test apparatus according to one embodiment (1) of the present invention includes a water tank 10, a torpedo tube 20, a torpedo 30, a shock absorbing pad 100, an elastic means 200, and a rail R.

The water tank 10 may be filled with water, for example, and may have the same environment as an underwater environment in which the torpedo 30 mounted on a submarine is launched.

The torpedo 30 is a self-propelled torpedo. The torpedo 30 may leave the torpedo tube 20 with its own propulsion.

The torpedo tube 20 is a passage through which the torpedo 30 is passed by launching the torpedo 30, and a torpedo launch speed measurement point P is provided at the front of the torpedo tube 20, and can be used for a torpedo launch test.

The rail R is a path through which the launched torpedo 30 is propelled outside the torpedo tube 20, and since the rail R is in an underwater environment, the speed of the torpedo 30 being propelled can be reduced according to the resistance of water.

The shock absorbing pad 100 is located in front of the torpedo tube 20, contacts the launched torpedo 30, and absorbs energy from the launched torpedo 30.

Specifically, the shock absorbing pad 100 is located in front of the torpedo tube 20, and the front end of the torpedo 30 is at a position where the rear end of the torpedo 30 passes the torpedo firing rate measurement point P. The initial position of the shock absorbing pad 100 can be determined so that it can contact the shock absorbing pad 100. Because, since the speed of the torpedo 30 should not decrease before measuring the speed of the launched torpedo 30, the rear end of the torpedo 30 passes through the torpedo launch speed measurement point P, and then the shock absorbing pad 100. It should be brought into contact with it.

For example, the shock absorbing pad 100 may be made of a material capable of absorbing shock, such as a sponge, to reduce damage to the torpedo 30. The shock absorbing pad 100 may be configured to move forward together by the accelerated torpedo 30 . At this time, the shock absorbing pad 100 can move along the path of the rail R together with the torpedo 30.

The elastic means 200 has one end fixed to the shock absorbing pad 100, and converts and stores the kinetic energy of the torpedo 30 and the kinetic energy of the shock absorbing pad 100 absorbed by the shock absorbing pad 100 as the launched torpedo 30 moves.

The elastic means 200 may include, for example, a spiral spring structure. Here, the elastic means 200 will be assumed and described as a spring. One of both ends of the elastic means 200 may be fixed to the center of the spring, and the other end may be fixed to the shock absorbing pad 100.

When the launched torpedo 30 pushes the shock absorbing pad 100, the kinetic energy of the torpedo 30 and the kinetic energy of the shock absorbing pad 100 are converted into internal energy of the spring spring, and force F is generated in the direction opposite to the propulsion direction of the torpedo 30, which can help stop the torpedo 30.

At this time, the larger the spring constant of the mainspring, the faster the energy conversion speed, and the shorter the torpedo deceleration section (A) of the torpedo launch test device.

4 is a diagram schematically showing a torpedo launch test apparatus according to another embodiment of the present invention.

Referring to FIG. 4, the torpedo launch test apparatus according to another embodiment (2) of the present invention includes a water tank 10, a torpedo tube 20, a torpedo 30, a forced injection device 40, a shock absorbing pad 100, an elastic means 200, and a rail R.

The water tank 10 may be filled with water, for example, and may have the same environment as an underwater environment in which the torpedo 30 mounted on a submarine is launched.

The torpedo 30 is a forced launch torpedo. The torpedo 30 does not have its own propulsive force, and the torpedo 30 can leave the torpedo tube 20 with the force pushing the torpedo 30 through the forced ejection device 40. The forced injection device 40 is a separate device that generates the firing force of the torpedo 30.

The torpedo tube 20 is a passage through which the torpedo 30 is passed by launching the torpedo 30, and a torpedo launch speed measurement point P is provided at the front of the torpedo tube 20, and can be used for a torpedo launch test.

The rail R is a path through which the launched torpedo 30 is propelled outside the torpedo tube 20, and since the rail R is in an underwater environment, the speed of the torpedo 30 being propelled can be reduced according to the resistance of the water.

The shock absorbing pad 100 is located in front of the torpedo tube 20, contacts the launched torpedo 30, and absorbs energy from the launched torpedo 30.

Specifically, the shock absorbing pad 100 is located in front of the torpedo tube 20, and the front end of the torpedo 30 is at a position where the rear end of the torpedo 30 passes the torpedo firing rate measurement point P. The initial position of the shock absorbing pad 100 can be determined so that it can contact the shock absorbing pad 100.

For example, the shock absorbing pad 100 may be made of a material capable of absorbing shock, such as a sponge, to reduce damage to the torpedo 30. The shock absorbing pad 100 may be configured to move forward together by the accelerated torpedo 30 .

The elastic means 200 has one end fixed to the shock absorbing pad 100, and converts and stores the kinetic energy of the torpedo 30 and the kinetic energy of the shock absorbing pad 100 absorbed by the shock absorbing pad 100 as the launched torpedo 30 moves.

Similarly, the elastic means 200 may include, for example, a spiral spring structure. One of both ends of the elastic means 200 may be fixed to the center of the spring, and the other end may be fixed to the shock absorbing pad 100.

When the launched torpedo 30 pushes the shock absorbing pad 100, the kinetic energy of the torpedo 30 and the kinetic energy of the shock absorbing pad 100 are converted into internal energy of the spring spring, and force F is generated in the direction opposite to the propulsion direction of the torpedo 30, which can help stop the torpedo 30.

5 is a diagram schematically showing a part of a torpedo launch test apparatus according to another embodiment of the present invention.

5 may include a plurality of elastic means 201 and 202, compared to the torpedo launch test device according to the above-described embodiments 1 and 2 of the present invention. Here, the first elastic means 201 and the second elastic means 202 are exemplarily shown.

In the torpedo launch test apparatus according to another embodiment (3) of the present invention, the location of the shock absorbing pad 100 in front of the torpedo 30 being propelled along the rail R is the same, and there is a difference in the number of elastic means 201 and 202 fixedly connected to the shock absorbing pad 100.

For example, the first and second elastic means 201, 202 may be installed in the circumferential direction of the projected path of the torpedo 30 being propelled, and may be composed of a plurality of springs according to system efficiency. That is, each of the first and second elastic means 201 and 202 may be formed in a spring structure.

When the launched torpedo 30 pushes the shock absorbing pad 100, the first and second elastic means 201 and 202 convert the kinetic energy of the torpedo 30 and the kinetic energy of the shock absorbing pad 100 into the internal energy of the spring, generating forces F1 and F2 in the direction opposite to the propulsion direction of the torpedo 30, thereby helping to stop the torpedo 30.

The first and second elastic means 201, 202 may be installed in a symmetrical structure so that no moment is applied to the shock absorbing pad 100 when the torpedo 30 contacts the shock absorbing pad 100.

5 shows a structure in which the first and second elastic means 201 and 202 are disposed above and below the shock absorbing pad 100 as an example. However, the present invention is not limited thereto, and a plurality of elastic means may be arranged in a vertical and horizontally symmetrical structure, and the number of the plurality of elastic means may be selectively determined according to system efficiency.

In the above, the land torpedo launching test device according to the embodiments of the present invention has been described with reference to the drawings, but the above description is illustrative and has ordinary knowledge in the art within the scope of not departing from the technical spirit of the present invention. It will be possible to modify and change.
