BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a submarine launching system and a submarine launching system using a gas generator,

The present invention relates to a system and a method for launching a submarine using a gas generator, and more particularly, to a submarine launching method using a gas generator capable of forcibly launching a submarine using a gas generator employing an airbag chemical principle System and method.

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 them, the water ram system is a piston driven by hydraulic pressure or pneumatic pressure, and the water in the cylinder is supplied to the tube to emit the armed force.

FIG. 1 is a view schematically showing an arming and launching system according to a conventional water-ram system.

Referring to Fig. 1, a gun 10 is mounted in a launch tube 1. The cylinder 40 provided for the forward and backward movement of the water piston 30 is connected to the hydraulic accumulator 20 and the fluid tank 50.

According to this structure, the water piston 30 can be pulled backward by using the hydraulic pressure accumulated in the hydraulic accumulator 20, and the water pressure generated in this case can be used to forcibly fire the armed weapon 10 .

However, according to the conventional water ram system, since the volume of the hydraulic accumulator itself is large, a large installation space has been required, and it has been difficult to effectively control the emission speed depending on the type of armature.

2, a submarine launch vehicle system 100 using a gas generator includes a gas generator 110 and a gas generator 110. The submarine launcher system 100 includes a gas generator 110 and a gas generator 110. The submarine launcher 100 includes a gas generator 1, a cylinder 40, and a water piston 30. And may include an exhaust tank 120.

The launch tube 1 is equipped with a submarine such as a torpedo or an underwater arming device 10 and provides a space in which the armed device 10 is fired.

The cylinder 40 can be connected to the duct between the launch tube 1 and the seawater passage.

A water piston 30 may be provided to move in both directions within the cylinder 40.

The gas generator 110 is similar to a conventionally known air bag, and can generate gas by a chemical reaction.

The gas generated by the gas generator 110 can be supplied to the front of the cylinder 40 to move (i.e., retract) the water piston. The water pressure generated at this time causes the armature 10 May be forcibly fired from the launch tube 1.

For example, the gas generator 110 may be configured to generate nitrogen gas through a chemical reaction of sodium azide. That is, nitrogen gas can be generated through a chemical reaction of 2NaN3 -> 2Na + 3N2.

In addition, although not shown separately, the gas generator 110 may generate a necessary current from a submarine or underwater battery so as to cause a chemical reaction of the sodium azide described above.

According to this principle, the gas generator 110 can control the kind of the arming or the rate of fire by controlling the amount of sodium azide and the reaction temperature according to the heat generation.

In this way, when the gun 10 is fired using the gas generator 110, the installation space can be reduced and the arming and launching control can be facilitated compared with the case of using the conventional hydraulic accumulator have.

The exhaust pipe 40 is connected to the cylinder 40 so that the gas remaining behind the cylinder 40 when the water piston 30 moves (i.e., retracted) is exhausted to the outside of the cylinder 40, (120).

Meanwhile, various types of valves 130, 131, 133, and 135 may be further included in the arming and launching system 100 of the submarine using the gas generator according to an embodiment of the present invention.

For example, a pipe connecting the exhaust tank 120 and the cylinder 40 may include a first valve 131, and the first valve 131 may be connected to the gas generator 110 through both ends of the cylinder 40 A second valve 133 and a third valve 135 may be provided in the pipe.

FIG. 3 (a) is a view showing a state in which a weapon 10 is mounted in a launch tube 1, FIG. 3 (b) shows an operation in which the armament 10 is forcibly fired by the tube 1a.

In particular, referring to FIG. 3 (b), a current is supplied from the battery in the gas generator 110, and heat is generated. As a result, nitrogen gas can be generated through the chemical reaction of sodium azide. In addition, the first valve 131 and the third valve 135 may be opened to fire the armed weapon 10.

The gas existing in the cylinder 40 due to the opening of the first valve 131 may be exhausted through the pipe and may be discharged toward the exhaust tank 120.

The gas generated from the gas generator 110 is supplied to the front of the cylinder 40 in accordance with the opening of the third valve 135 and the water piston 30 is moved in the retreating direction Direction).

 At this time, the sea water flowing from the seawater passage in conjunction with the movement of the water piston 30 pushes the armed weapon 10 with a strong water pressure. As a result, the armed weapon 10 is forcibly fired from the launcher 1 .

On the other hand, the second valve 133 and the third valve 135 may be opened to reload the armed robots. That is, the gas can be transferred to the second valve 133 through the third valve 135 opened according to the regeneration circuit, and the reloading of the armed weapon 10 can be enabled.

In the water piston moving step S200,

This step is a water piston moving step, in which the gas generated in the gas generator in the previous step is supplied to the cylinder to move the water piston.

Thus, by moving the water piston toward a predetermined direction (e.g., retracting direction), it is possible to produce a strong water pressure necessary to fire the armament.

The armed launch phase (S300)

This step is a step of launching an armed force, and the army can be forcibly fired from the launching tube by using the water pressure generated as a result of moving the water piston in the previous step.
