Description

Armed injection device and method using bilge pump {APPARATUS AND METHOD FOR LAUNCHING WEAPON USING BILGE PUMP}

The present invention relates to an arming injection device and method using a bilge pump, and more particularly, to a high-pressure bilge pump in a submarine, to fill the membrane rubber with compressed water, and to use the elastic force of the membrane rubber and compressed air to arm the launch tube. It relates to an armed injection device and method using a bilge pump that can force injection.

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

Armed firing methods can be broadly divided into the self-navigating type (Swim out), which escapes the launch tube by the propulsion of the weapon itself, and the forced discharge method (positive discharge), which pushes the armament from the submarine.

The currently introduced forced firing method includes a method using compressed air, a method using compressed water, and a method using mechanical force. Among them, the method of using compressed water is mainly used in two ways, the method using an air turbine pump (ATP) and the water ram method. In addition, a linear pump, a rotary There is a method using a pump (Rotary Pump), etc.

In the case of an air turbine pump, compressed air is used to turn a turbine and supply compressed water to the launch tube to fire weapons. Water ram is a hydraulic cylinder and a water cylinder It is a method of firing weapons by moving a piston inside and supplying compressed water to the launch tube.

However, in the case of the method using the air turbine pump, expensive turbine technology is required and maintenance is difficult, and the method using the water ram requires expensive hydraulic driving technology. In addition, the method using these air turbine pumps and water rams required high-pressure air and hydraulic cylinders.
