Gas distribution system and gas distribution method for incendiary bomb

Abstract

The invention discloses a combustion bomb gas distribution system. The system comprises a combustion bomb, a pressure relief tank, a gas storage tank, a gas distribution pipeline and a pressure reliefchannel, wherein a pressure release valve is mounted on the pressure release channel. The invention discloses a combustion bomb gas distribution method. The method comprises the following steps: preheating the combustion bomb, filling the pressure relief tank with gas, closing the pressure release valve, opening the air distribution valve, enabling gas in the gas storage tank to enter the combustion cavity to form combustible mixtures, closing all inlets and outlets of combustion bomb, and performing ignition, wherein in the combustion process, when the pressure in the combustion bomb is greater than the pressure in the pressure relief tank, the gas can burst through the pressure relief valve to relieve pressure; when the pressure in the combustion cavity is relieved to be lower than thepressure in the pressure relief cavity, the pressure relief valve can close the pressure relief channel and stop pressure relief, and after the gas is completely combusted, waste gas in the combustionbomb is exhausted through the first exhaust port. In the using process, the gas distribution system and the gas distribution method for the combustion bomb are large in pressure bearing range and various in combustion variety, and the research progress of flame propagation of the combustion bomb under the high-pressure working condition is effectively improved.

AI Technical Summary

Problems solved by technology

[0003] At present, the flame propagation experiments of constant volume incendiary bombs in China mainly focus on the research in the range of low pressure and normal temperature, while the flame propagation experiments of incendiary bombs under high pressure conditions are not only rarely studied but also have many problems. The main problem is that the pressure range of incendiary bombs is limited. The problem of limited combustion types and few types of combustion makes it difficult to study flame propagation
