摘要

摘要: 全浸水带间隙发射方式可以将发射环境由水介质转化为气体介质。为了研究高速射弹在此条件下的入水冲击载荷，建立了射弹入水冲击载荷的理论模型。针对射弹在入水速度、头部锥角和入水攻角不同情况下的入水冲击载荷进行了计算，分析了入水速度、射弹头部参数和入水攻角对冲击载荷的影响。研究结果对全水下高速射弹入水冲击载荷的预测和射弹头部结构的设计具有重要意义。

Abstract: The emission environment can be transformed from water medium to gas medium by water immersion gap-exist launch mode. In order to study the driving impact load of high speed projectile under this condition, the theoretical model of projectile impact load is established. The inlet impact loads of the projectile under different conditions of inlet velocity, head cone angle and inlet attack angle are calculated. The influences of inlet velocity, warhead parameters and inlet angle of attack on driving impact load are analyzed. The research results are of great significance to the prediction of the driving impact load of high-speed underwater projectile and the design of warhead.
