摘要
为了给某小口径杀伤破甲弹引信设计提供参考,运用GAMBIT建立弹丸外流场数值仿真模型,通过FLUENT对弹丸外流场进行了数值仿真以获取相关的气动力规律。仿真结果与1943年阻力定律基本一致,计算所得的气动参数可以为小口径杀伤破甲弹引信的外形设计提供依据与参考。
In order to provide a reference for design of the small-caliber high explosive ammunition fuze, projectile flow field numeri- cal simulation model is established by GAMBIT and the projectile flow field is simulated by FLUENT to obtain the relevant law of aero- dynamic force. The simulation results agree with 43 basic law of resistance, calculated aerodynamic parameters provide basis and reference for the design of the appearance of the small-caliber high explosive ammunition fuze.
