摘　　要：旨在为内埋武器的投放安全性,分析了攻角和舱门对开式武器舱流动特性的影响。结合嵌套网格方法并耦合六自由度运动方程研究了内埋式导弹在超声速条件下的分离轨迹和姿态变化,分析了不同马赫数对重力投放和弹射投放两种分离方式导弹分离轨迹的影响。计算结果表明,攻角和舱门不能改变开式武器舱的流动类型;两种分离方式都能使导弹安全分离,但是重力投放下导弹的俯仰角变化较大,不利于导弹点火发射。In view of separation safety of internal weapons,influence of attack angle and door on flow characteristics of an open-style weapon bay was analyzed. Overset grid method coupling with six-degree-of-freedom equation was developed to analyze trajectory and attitude variation of internal store separation from a weapon bay at supersonic speed,and the effect of Mach number on the trajectory of two different separation approaches was investigated. The results indicate that the attack angle and door are not able to change flow style of open-style weapon bay,and safe store separation can be realized in any of the two approaches. However,the attitude angle for the gravity separation approach during separation is adverse to ignite.
