This paper reports research results of a new rapid multiple point ignition system. The interior ballistic performance of this new ignition system is calculated by means of an axial symmetrical, two dimensional, two phase flow program and is compared with a traditional ignition system. Simulation tests in the gun steel tube simulator and shoot experiments for examining characteristics of the new ignition system are completed. p-t curves, maximum pressure at the bottom of the chamber, negative pressure difference and initial velocity of the projectile are obtained. The results show that this ignition system is feasible when used in a larger caliber gun, that the uniformity, synchronism, safety and reliability of ignition can be improved considerably, and that the energy utilization of the propellants raised greatly.
