In order to study the safety of a shot SRM, a simulation model was established. Ignition and growth reactive flow equation was applied to describe the ignition process of the impacted propellant. The process of SRM being shot was simulated numerically by use of nonlinear finite element method of fluid dynamics. It was demonstrated that the critical velocity of the shot SRM exploding is 850~855m/s, and the max pressure was in the wave front during the initiation caused by impact.
