为提高鱼雷非接触爆炸对水下目标的毁伤效果，提出一种新的鱼雷爆-破串联聚能战斗部的设计方案，前级为爆炸装药，后级为聚能装药，利用前级爆炸产生的气泡为后级的爆炸成型弹丸（EFP）提供前进通道，有效降低EFP的飞行阻力和能量损耗。采用AUTODYN数值计算软件，模拟EFP在空气、水和气泡中飞行情况，对比分析了EFP的速度变化和变形及对靶板的毁伤情况，验证了此设计方案的可行性和优越性。
A new type of torpedo tandem warhead was designed for enhancing the damage effect of underwater target when non-contact explosion. The forward charge of tandem warhead is an explosive charge,when exploding,it can form a bubble,the following shaped charge can form a EFP,flying through the bubble. This method can effectively reduce the flight drag and energy loss of EFP. The numerical software AUTODYN was applied to simulate EFP flying in the air,in the water and in the bubble. The shape changes and velocity changes of the EFP with time were comparatively analysed in three conditions. At last, the feasibility and superiority of this design were verified.
