Abstract

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.

Key words： internal weapon bay; separation approaches; overset grid; 6DOF
