高密度金属弹药组成比例对杀伤半径的影响

Effect of Configuration Proportion of High-Density Metal Ammunition on Killing Radius

为适应现代城市巷战的需求,提出了一种高密度金属弹药,介绍了该弹药的结构组成和作用原理,推导出高密度金属粉末的抛撒速度与复合材料外壳、装药三者之间的关系模型.通过静爆试验,比较了相同外壳情况下金属粉末与装药在3种不同比例结构组成时弹药爆炸后的威力特性,其中利用压力传感器测试得到爆炸后的压力曲线,利用25 mm厚松木靶构成扇形靶计算杀伤半径,通过高速摄影分析得到金属粉末的抛撒速度.试验结果表明,当装药与金属粉末的比例在一定范围内时,该弹药可有效降低附带毁伤.

To satisfy the need of fighting in urban environment, a new kind of high-density metal ammunition was put forward. The configuration and operational principle of this ammunition were introduced. The relation model of the dispensing velocity of high-density metal powder, composite material shell weight and metal powder weight was derived. Under the same conditions of shell, the blast power of ammunition consisting of metal powder and explosive charge in three kinds of proportions was compared by static explosion experiment. In the experiment, the overpressure curve was measured by pressure sensor. The killing radius was computed from the sector target using 25 mm deal board. The dispensing velocity of metal powder was obtained by high speed photography. The results show that the high-density metal ammunition can reduce collateral damage effectively while the proportion of explosive and highdensity metal powder is in a definite range.
