偏心起爆定向战斗部威力研究

为研究偏心起爆定向战斗部毁伤威力,推导了偏心起爆点对侧延长线附近有限角度内应用的偏心起爆破片初速公式,并设计钨柱和钨球两种预制破片偏心起爆定向战斗部进行了试验验证。结果表明,所推导公式可用于偏心起爆定向战斗部计算。设计的偏心起爆战斗部的速度增益,钨柱破片为10.9%,钨球破片为19.8%。钨球破片初速、破片球面分布密度、毁伤概率均高于钨柱破片。

Lethality Investigation of Azimuthal Warhead

To study the lethality of azimuthal warhead, a fragment muzzle velocity formula used in limited angles of extension line opposite to azimuthal detonating point of azimuthal warhead was deduced, and tungsten cylinder fragment and tungsten sphere fragment azimuthal warheads were designed to validate the model by experiments. Results show the formula can be used to the calculation of azimuthal warhead. The designed azimuthal warhead velocity gain is 10.9% for tungsten cylinder fragment and 19.8% for tungsten sphere fragment. The muzzle velocity, sphere distribution density and killing probability of tungsten sphere fragment are better than those of the tungsten cylinder fragment.
