Experimentation and Fragment Flight Analysis of Low-Collateral-Damage Warhead with Nonmetal Shell

Institute of Systems Engineering, CAEP, Mianyang 621999, China

摘要

摘要: 为了研究低附带战斗部的非金属破片飞散特性，结合某低附带杀伤战斗部静爆威力实验，对战斗部爆炸产生的非金属破片初速以及速度衰减情况进行了分析。基于能量守恒得到了包含壳体结构和材料强度因素的破片初速公式；基于破片在空气中飞行运动情况的分析，通过对球形破片阻力公式和等效面积进行修正，得到了非金属自然破片的速度衰减规律。所得结果较好地解释了战斗部静爆实验中的破片终点效应情况，亦可为该类战斗部破片毁伤效应评估提供一种分析方法。

Abstract: In this work we examined and characterized the original velocity and flight velocity attenuation of the nonmetal fragments of a certain low-collateral-damage warhead in combination with its explosive power experiment.We obtained the fragments' original velocity including the shell configuration and material strength factors based on the conservation of energy, and derived the flight velocity attenuation regularity from the analysis of its fragment flight movement in the air and the modification of its resistance formula and the equivalent area of the spherical fragment.Our analytical result was confirmed by the experimental result, thus providing an analytical method for evaluating the fragment damage efficiency of this kind of warhead.
