摘要
多燃气发生器弹射动力系统可以随温度变化调节发射内弹道,通过对多个燃气发生器进行不同步点火,获得导弹在多股燃气生成并相互作用下发射过程的内弹道参数。针对多个燃气发生器的弹射动力系统,使用Matlab编程并求解内弹道微分方程组,对同一弹体在3种不同温度发射工况进行内弹道仿真试验,结果表明在不同时序对不同燃气发生器点火,可以使弹射动力系统得到基本一致的出筒速度。此项研究可为多燃气发生器发射动力系统的内弹道设计提供重要的依据。
The temperature adaption of interior ballistic for missile ejecting power system with multi- gas generators is studied. After asynchronous ignition for multi-gas generators, the mixed combustion gas interacts in the launching canister and the interior ballistic parameter can be obtained. The interior ballis- tic differential equations are solved using Matlab. The interior ballistic simulation for missile launching at three different temperatures is simulated. The results show that the same detached velocity of missile can be achieved by successively firing the gas generators at certain interval. The research can greatly support the interior ballistic design of missile launching power system.
