针对集群聚能串联战斗部设计思想,将前级对目标的破坏简化为开孔预破坏,开展了弹丸对预开孔混凝土靶体的实验研究,分析了靶体开孔形式对弹丸侵彻性能的影响。结果表明,弹丸对预开孔靶体的侵彻深度随靶体开孔数量和开孔深度的增加而增加,相对说来,增加开孔数量相当于增加了靶体破坏面积,对提高后级侵彻能力更为有效。研究结果可为串联战斗部的前级集群聚能装药设计提供参考。

According to the design idea of multiple-shaped-charge tandem warhead, target damage by forward warhead was simplified as borehole pre-damage, and the experimental investigation was carried out on projectile penetrating to pre-borehole concrete target in this paper. The influence of borehole model of target on projectile penetration capability was analyzed. As a result, the increase of projectile penetration depth was followed by increase of borehole amount and depth. Comparatively, the increase of borehole amount is more effective because the increase of borehole amount is equivalent to the increase of damage area of target. The results can provide reference for the design of forward multiple-shaped-charge in tandem warhead.
