某箱式火箭炮对面目标分布式杀伤最优火力分配

Optimal Fire Distribution of a Rocket Launcher against Area Target

为了提高某箱式火箭炮的作战效能,提出一种基于分布式多点射击效率评定的最优火力分配方法,建立了射击效率评定模型和火力分配模型。以平均相对毁伤面积为射击效率指标,通过对面积目标网格微元积分,以最大射击效率为目标函数进行优化搜索,在求取射击效率的基础上确定出射击点的数量和坐标。区分目标中心单点射击和分布式多点射击两种情况进行了对比计算,结果表明:两种射击方法的射击效率均随用弹量的增加而增大;采用分布式最优火力分配方法比单点射击方法的射击效率大幅提高,最高可达17.28%.

An optimal fire distribution method based on distributed firing efficiency evaluation is proposed to improve the firing efficiency of a rocket launcher. The models of firing efficiency evaluation and fire distribution are established. The mean relative damage area is considered as the index of firing efficiency evaluation,and the maximal firing efficiency is considered as the object function. The firing point and coordinate could be calculated by integrating the microgrid of area target. Two firing methods,i. e.,single point firing and distributed multi-point firing,are designed for the calculation of firing efficiency. The calculated results show that the firing efficiencies of both methods increase with the increase in ammunition consumption,and the firing efficiency of optimal fire distribution method is 17. 28% higher than that of single point firing method.
