摘　　要：介绍了双燃烧室活塞式子母弹抛撒机构 ,利用均相流理论 ,建立了高压室均相流内弹道方程组 ,和低压室经典内弹道方程组 ,利用数值模拟得到了燃烧室的 p～ t曲线和子弹的抛撒速度 ,并对高压室内的压力波进行了分析 。The submunition dispensers with two combustion chambers are introduced in this paper. The interior ballistic equations of the high-pressure-combustion are established based on the quasi-two-phase flow and the classical interior ballistics equations are established for the low-pressure-combustion. The p～t curve of the two combustion chambers and the velocities of the submunition are derived with simulaion. And the pressure wave in the high-pressure-chamber is analyzed and some methods to decrease the pressure wave are presented.
