Calculation Model of Optimum Burst Height of Blast-fragmentation Warhead Based on Physical Damage Area

为解决地面目标的多样性和随机性导致平均效率面积难以准确计算的问题,提出基于物理杀伤面积的杀爆战斗部杀伤威力评定方法,并以此作为确定杀爆战斗部最佳炸高的依据。由给定的末端弹道参数及杀爆战斗部破片参数,建立物理杀伤面积的计算模型,编制计算程序并以物理杀伤面积最大作为确定炸高的条件。计算结果表明:导弹落速及导弹落角对杀爆战斗部最佳炸高均有较大影响。该方法可作为杀爆战斗部最佳炸高确立以及破片参数优化的依据。

In order to solve the problem that it is difficult to calculate the average efficiency area accurately because of the diversity and randomness of ground targets, the lethality evaluation method of blast-fragmentation warhead based on physical lethality area is proposed, which is used as the basis for determining the optimal blast height of blast-fragmentation warhead. According to the given terminal ballistic parameters and fragmentation parameters of blast-fragmentation warhead, the calculation model of physical damage area is established, the calculation program is compiled, and the maximum physical damage area is taken as the condition to determine the burst height. The results show that the impact velocity and impact angle of the missile have great influence on the optimal height of the blast-fragmentation warhead. This method can be used as the basis for determining the optimal burst height of the blast-fragmentation warhead and optimizing the fragment parameters.
