Gas generator propellant grain

Abstract

Provided is a gas generator propellant grain. Gas generator propellant is filled in a supporting barrel, more than one combustion-supporting hole is formed in a position, corresponding to the gas generator propellant, of the circumferential surface of the supporting barrel, an axial through hole is formed in the gas generator propellant, a position, making contact with the supporting barrel, of the side face of the gas generator propellant is provided with a lining, and combustion-limiting layers are installed on two end faces of the gas generator propellant. The gas generator propellant grain starts to burn simultaneously from the axial through hole and the combustion-supporting holes in the side face of the supporting barrel, the combustion face tends to increase, and produced gas flows to an exhaust hole of a gas generator through the inner axial through hole and the surface of the supporting barrel. The gas generator propellant grain used for guided missile ejection power devices has the advantages that the gas is produced rapidly, the combustion temperature is low, the gas producing quantity is gradually increased over time, and the change rule is controllable.

Description

technical field [0001] The invention relates to a gas generating agent grain column which provides working energy for a missile weapon type ejection power device. Background technique [0002] At present, the ejection power forms of domestic and foreign missiles mainly include: compressed air type, steam type, gas type, gas-steam type, and electromagnetic type. Among them, the volume of compressed air, steam and electromagnetic equipment is too large to be convenient for transportation and mobile launch. The volume of the gas-steam type device is much smaller than that of the compressed air type, steam type, and electromagnetic type, and it has a wide range of applications. It is the main power form used by missile launches in various countries. Gas-fired ejection is to directly act on the bottom of weapons such as missiles with gunpowder gas, and convert the chemical energy of gunpowder into kinetic energy to drive missiles. Compared with gas-steam devices, it has large en...

AI Technical Summary

Problems solved by technology

Gas-fired ejection is to directly act on the bottom of weapons such as missiles with gunpowder gas, and convert the chemical energy of gunpowder into kinetic energy to drive missiles. Compared with gas-steam devices, it has large energy, small volume, and relatively simple equipment. However, due to the high temperature of the gas in the general gunpowder, the temperature in the launch tube is too high
