为了研究固体火箭发动机的烤燃安全性,建立固体火箭发动机烤燃仿真模型,并将通过发动机壳体火烤试验获得的温度边界条件加载到仿真模型中,获得了2种烤燃温度下固体火箭发动机的仿真结果。仿真结果显示,固体火箭发动机中的点火药首先达到发火点,是固体火箭发动机烤燃安全性中的薄弱环节。
In order to reseach the cook-off safety of solid rocket motor (SRM), a cook-off simulation model of SRM was established, and the temperature boundary conditions obtained from the engine shell cook-off test were loaded into the simulation model, and the simulation results of SRM under two kinds of cook-off temperatures were obtained. The simulation results show that the ignition powder of SRM reaches the ignition point first, which is the weak link in the baking safety of SRM.
