An analysis of the penetration-explosion (PE) effects of four distributions of inactive/active composite jets shows that a well-designed inactive/active double-layer liner can promote composite jet damage. Penetration experiments were then carried out for shaped charge jets having a single inactive (Cu) liner or an inactive/active (Cu/Al) double-layer liner with variable liner height. The behaviors and firelight patterns of the different jets were captured by high-speed photography. The perforation, deformation area, and deflection were measured for each plate, showing that the Cu/Al jets have stronger PE effects. Numerical simulation shows that the tip of the composite jet generated from the full-height liner is only Cu, whereas for the other jet, from the double-layer liner, Cu is almost wrapped entirely by Al.
对四种惰性/活性复合射流分布的侵彻-爆炸（PE）效应分析表明，精心设计的惰性/活性双层药型罩可增强复合射流的毁伤效果。随后，对具有单一惰性（铜）药型罩或惰性/活性（铜/铝）双层药型罩且药型罩高度可变的聚能射流进行了侵彻实验。通过高速摄影捕捉了不同射流的行为和火光模式。测量了每块靶板的穿孔、变形区域和挠度，结果表明铜/铝射流具有更强的PE效应。数值模拟表明，由全高药型罩产生的复合射流尖端仅为铜，而对于双层药型罩产生的另一种射流，铜几乎完全被铝包裹。
