【Abstract】 To investigate the ignition and combusion behavior of gun propellant under the action of high temperature fragment,a heated steel cylinder was chosen as simulation fragment,the ignition and combustion process of gun propellant under the action of high temperature fragment were simulated.An experimental device used for hot fragment conductive ignition was set up,the characterization parameters of the vulnerability of the gun propellant under the action of heated fragment were determined,and the ignition and combusion behavior of double-base gun propellant under the action of heated fragment were studied.The results show that the fragment temperature,fragment size,type dimension and environmental condition of sample are principal factors affecting the hot fragment conductive ignition of the propellant with same formula.更多还原
