导弹发射过程同心筒内燃气流场研究

Research on the Combustion Flow Field in the Concentric Canister Launcher During Missile Launch

同心筒内燃气流能否顺利排导,关系着导弹发射的成败,为了研究导弹发射过程中同心筒内的燃气流场情况,论文采用了数值模拟的方法来进行研究,得到了导弹发射过程中同心筒内不同位置燃气流的速度、温度和压力等参数值随时间的变化情况,并用数值模拟的方法研究了同心筒前盖不同破碎条件对同心筒内燃气流场的影响,为同心筒的设计优化提供了参考。

The success or failure of missile launch depends on whether the internal combustion air flow in the concentric canis⁃ter launcher can be successfully discharged or not.In order to study the air flow in the concentric canister launcher during missile launch,the research is carried out by the methods of numerical simulation.The changes of gas flow velocity,temperature and pres⁃sure at different positions in the concentric canister launcher with time are obtained.The influence of different crushing conditions on the airflow field is studied by numerical simulation.It provides reference for the design optimization of concentric canister launcher.
