Description

[0001] UNDERWATER WEAPON LAUNCH APPARATUS AND METHOD [0002]

The present invention relates to an apparatus and method for launching a water rammed underwater weapon, and more particularly, to a water ramming weapon launching apparatus and method capable of rapid arming loading by returning a piston after draining a gun, will be.

Generally, combat submarines are equipped with armed forces such as torpedoes, missiles, and mines for attacking enemy ships or enemy submarines, and they are launched by various launch systems.

The armed firing method can be divided into the swim out, which departs from the launch tube, and the positive discharge, which pushes the armed forces in the submarine. Among them, the forced fire method is divided into Direct Air, Water Ram System and Air Turbine Pump System.

Among the armed firing methods, the water ram method is a hydraulic or pneumatic piston, which supplies water in the cylinder to the launching tube and fires armed. Generally, for launching the armed forces, it is necessary to add the launching tube to the seawater first, and then to discharge the attached tube after the arming.

FIG. 1 is a schematic view of a conventional water ram system. In particular, the illustrated charge and discharge system includes various valves having different functions.

For example, a compressed air supply valve (LP Blow Valve), a changeover valve (Change Over Valve), a transfer valve, a vent vent valve, a Fwd Vent Valve, Equalize Valve, F & D Valve, and the like.

However, in order to launch the armed weapon, it is necessary to open and close the various valves in order to attach the launching tube first and then to discharge the injected tube after discharging the armed weapon and to load the weapon to be fired thereafter. Compressed water in the tube was drained to the WRTT. This took about several minutes of operation time.

Therefore, it is required to develop a technique capable of loading the weapon in a shorter time.

The terms and words used in the present specification and claims should not be construed as limited to ordinary or dictionary meanings and the inventor shall appropriately define the concept of the term in order to describe its invention in the best way It should be construed in accordance with the meaning and concept consistent with the technical idea of the present invention. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are only the most preferred embodiments of the present invention, and not all of the technical ideas of the present invention are described. Therefore, It should be understood that various equivalents and modifications may be present.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus and method for launching a water-ramped water weapon according to embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is an operation diagram of an armed launch using a water-rammed underwater arming device according to an embodiment of the present invention, and FIG.

2 and 3, a water ram system underwater arming device according to an embodiment of the present invention includes a tube 101, a cylinder 130, a water piston 120, a water transfer tank 103, (140).

The launch tube 101 is a space for launching a weapon of a submarine. An opening and closing door may be formed at the rear of the submarine for loading the weapon, and a bow cap may be provided at the front to open the weapon when the weapon is fired.

The cylinder 130 is connected to the water piston 120 and the water piston 120 can be formed to be movable in both directions (i.e., forward or backward) within the cylinder.

For example, in order to launch the armament, the water piston 120 is retracted and the water piston 120 is driven forward when the water piston 120 is advanced from the cylinder. At this time, when the water piston 120 advances from the cylinder, It is possible to simultaneously drain the compressed water in the water tank. As a result, it is possible to shorten the loading time of the armed weapon, thereby enabling the armed weapon to be armed more quickly.

In addition, by using a water transfer tank 103 formed in communication with the water pipe 101 and the water piston 101 when the water piston 120 advances and returns without using a separate water discharge valve or the like, Can be performed.

 The hydraulic actuator 140 may supply the working fluid into the cylinder 130 to move the water piston 120 forward or backward.

To this end, the hydraulic drive unit 140 includes an accumulator or hydraulic tanks 141a and 141b, hydraulic lines 131a and 131b connected between the hydraulic tank and the cylinder to supply a working fluid, and a plurality of valves 143a and 143b , 145a, 145b. The water piston 120 may be moved forward or backward according to opening and closing operations of the hydraulic tank and the plurality of valves.

For example, as shown in FIG. 2, in order to supply compressed water to the launch tube 101 by the retraction of the water piston 120 and fire the armed W, the hydraulic tank of the reference numeral 141a and the valves of the reference numerals 143a and 145a Opening can be made.

As another example, in order to drain the tube 101 simultaneously with the advancement of the water piston 130 as shown in FIG. 3, the hydraulic tank of the reference numeral 141b and the valves 143b and 145b may be opened. However, the present invention is not necessarily limited thereto, and operation of the water piston 120 can be realized in a different manner.

FIG. 4 is a view schematically showing the structure of a water piston of a water-rammed underwater arming device according to an embodiment of the present invention.

4 (a) shows a simplified structure of the water piston 120. When the water piston 120 is retracted to emit an armed force, as shown in FIG. 4 (b) Plate structure. In contrast, when the water piston 120 advances and retreats, it may have a cross-sectional structure of a C-shape as shown in FIG. 4 (c) for reducing friction.

However, in order to smoothly drain the seawater inside the tube when the water piston 120 is advanced, sufficient pressure may not be formed for draining water if the structure is as shown in FIG. 4 (c). Accordingly, in order to drain the tube at the same time as advancing the water piston 120 as in the embodiment of the present invention, the water piston 120 is controlled to have a straight plate structure as shown in FIG. 4 (d) desirable.

As described above, according to the constitution and the function of the present invention, it is possible to return the piston after discharge of the armed force, and to drain the duct, so that the arming can be quickly loaded in a shorter time.

The water ram system underwater arming device and method of the present invention have been described with reference to preferred embodiments.

It is to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive, and the scope of the present invention will be indicated by the appended claims rather than by the foregoing detailed description. It is intended that all changes and modifications that come within the meaning and range of equivalency of the claims are to be embraced within their scope.
