以分区拼接网格数值模拟方法为基础,通过气动方程和弹道方程联立求解数值模拟了子弹从母弹中分离并穿越母弹激波的过程,研究了子母弹干扰流场的气动特性,分析研究了子弹各初始分离状态(如初始抛撒速度、初始姿态角、初始姿态角速度等)对分离过程的影响。
Based on the numerical simulation method of zonal splicing grids, the numerical simulation of the separation of projectiles from the projectile and the penetration of the projectile shock wave was carried out by solving the numerical equations of the aerodynamic equation and the ballistic equation. The aerodynamic characteristics of the submunition interfering flow field were studied. The initial separation of the state of the bullet (such as initial scattering speed, the initial attitude angle, the initial attitude angular velocity, etc.) on the separation process.
