对大型导弹自排导热发射全过程的燃气流场进行了详细的仿真分析,揭示了发射过程的燃气流场规律,给出了发射过程导弹所受燃气温度和压力冲击的规律、时间及强度,仿真结果与试验结果吻合较好。研究表明,通过合理设计,大型导弹自排导热发射燃气流可通畅、顺利排导,作用在导弹的温、压载荷较小,时间较短,为大型导弹自排导热发射方式的可行性提供了研究依据。
The simulation and analysis of gas flow field in the whole course of self-guided thermal emission of large missile is carried out. The regularity of gas flow field during launching process is revealed. The law, time and intensity of gas temperature and pressure impact on missile during firing process are given, The simulation results are in good agreement with the experimental results. The research shows that, through rational design, the large gas missile can emit gas flow smoothly and smoothly from the heat conduction by heat conduction. The heat and pressure load acting on the missile is small and the time is short, which provides the feasibility of the self- Research basis.
