低密度射流对爆炸反应装甲毁伤的探索研究

破-破式串联战斗部是有效应对爆炸反应装甲的武器弹药之一，前级聚能战斗部能否可靠引爆夹层装药直接决定着战斗任务的成功与否.现有的前级聚能战斗部大多采用的是金属药型罩，而本文则是探索能否将低密度材料作为前级聚能战斗部的药型罩材料，来达到毁伤反应装甲的目的.本文从数值仿真和理论计算两个方面研究了低密度射流的毁伤特性，并将数值仿真结果与理论计算结果进行对比.结果表明，低密度射流不仅能够可靠引爆夹层装药，而且还具有很多优于现有金属射流的特点.因此，本文的探索研究具有一定科研价值，以期为工程设计提供参考.

Research on the Damage of Low-Density Jet to the Explosive Reactive Armor

The shaped charge-shaped charge type tandem warhead is one of the weapons which can effectively deal with the explosive reactive armor, whether the pre-warhead can reliably initiate the sandwich charge directly determines the success of the combat mission. Most of the former shaped charge warheads are made of metal liner, while this article is to explore whether the low-density material can be used as the liner material, so as to achieve the purpose of damaging explosive reactive armor. The damage characteristics of low density jet are studied with numerical simulation and theoretical calculation, and the numerical simulation results are compared with the theoretical calculation results. The results show that the low-density jet not only can reliably initiate the interlayer charge, but also has many advantages over the existing metal jet. Therefore, this paper has the scientific research value to provide reference for the engineering design.
