Analysis of Firing Safety of High Chamber Pressure Gun

Abstract

In order to avoid the blasting accident of high bore pressure and high loading density gun, the safety of firing of coated mixed charge of high bore pressure gun is analyzed. In this paper, the safety analysis of the pressure waves, according to the theory of two phase flow and coated propellant layered model, using the pressure difference curve analysis and intensity of stress wave reflection and reflective research analysis method were analyzed, and it is found that the safety of pressure wave can be improved by selecting the right position of the fire hole in the first row of central fire transmission tube and the right ignition dose. Increasing the length of the fire transmitting tube can reduce the pressure wave and make the flow field in the bore stable.
