Experimental Study on A New Model Shaped Charge Warhead

本文根据能量利用的观点提出了一种新型聚能战斗部装药结构,指出开展其研究的重要价值;并对其射流与弹丸的成型过程和破甲机理进行了理论分析,在此基础上进行了系统的静破甲实验,并对该战斗部装药结构的一些关键结构参数(例如空孔孔径、炸高、小锥角聚能罩底面直径和锥角角度)和大、小锥角聚能罩材料之间的匹配关系对静破甲效果的影响进行了系统的分析研究。实验结果表明:在各自最佳炸高条件下,该新型聚能装药结构比普通EFP装药结构,在保持相当穿孔孔径、同等装药和壳体约束条件下,可以提高穿深达50%左右。进一步深化了聚能效应的内涵和丰富了打击目标的手段。

This paper presents a new model of shaped charge warhead from the energy consideration. The projectile forming process and the penetration mechanism of the shaped charge device is analysed. Based on the above analysis, the static penetration tests were systematically conducted in order to find the influence of the key configuration parameters (such as the aperture diameter, stand offs, the bottom diameter of small angle liner and the angle of the liner) and the match between the penetration results for the small angle liner material and these for the large angle liner material. It is shown that at the optimal stand offs, the penetration capability of the new device are about 50% higher than that of the ordinary explosively formed projectile with the comparative diameter of their craters under the same charge and casing conditions. Finally the new model shaped charge warhead deepens the connotation of shaped charge effects and enriches the means to defeat armored targets.
