Fuel gas generator capable of quickly inflating underwater ordnance floating system

Abstract

The invention discloses a gas generation device capable of providing a gas source for an underwater ordnance floating system. The gas generation device comprises a shell, a combustion chamber and a working chamber which are formed in the shell, and one or more igniters mounted at one end of the shell, wherein a filter sleeve is mounted in the shell; the filter sleeve comprises a large outer sleeve and a small inner sleeve; the combustion chamber is formed through filling the small inner sleeve with a low-temperature gas generant; the working chamber is formed through filling a chamber between the inner wall of the large outer sleeve and the outer wall of the small inner sleeve with the low-temperature gas generant; and a plurality of exhaust holes are formed in the side surface of the shell. The gas generation device has the advantages of simple structure, light weight, low generator inner pressure, stable outlet pressure, low dust, low outlet gas temperature and the like, and requirements of quick floating of underground objects and inflation of airtight sacs in water and air rescue can be met.

Description

technical field [0001] The invention relates to a gas generator. Background technique [0002] The underwater weapon test bomb needs to be recovered during the test to obtain test data. If a long rope is carried into the water during the test, the ballistic performance of the test bomb will be affected. During long-distance horizontal movement, the rope cannot be recovered at all, so a An emergency floating system, the system is composed of a controller, a gas generator, an air bag, etc., and can be installed on the test bomb without affecting the normal operation of the test bomb. When the test bomb is finished, the water depth controller sends an ignition signal to start the gas The generator produces a large amount of low-temperature gas to rapidly expand the capsule to obtain buoyancy, and float the test bomb out of the water. The system requires the gas generator to have the characteristics of large gas output, fast start-up, low gas temperature, and few solid particle...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems that the underwater weapon test process needs to be recovered with a rope, which affects the ballistic accuracy, etc., the present invention provides a gas generator that provides rapid inflation for the floating system of the underwater weapon. It has a simple structure, light weight, and low internal pressure. Stable outlet pressure, less dust, and outlet gas temperature
