摘　　要：针对机动再入式大型杀爆战斗部,以杀伤面积最大化为目标,通过建立破片分布及运动特性模型,基于破片飞散方向的统计规律,求出不同爆高下破片的终点状态及分布区域,得到最大杀伤面积对应的爆高,即为最佳爆高。计算结果表明:不同的末端弹道条件下,都存在一个对应最大杀伤面积的最佳爆高;且当速度、姿态角增大,最大杀伤面积及最佳爆高也随之增大。Aiming at maximizing the lethal area of maneuvering reentry large-scale blast-fragmentation warhead,by building the distribution and motion model of fragment,based on the statistics of the fragment flight trajectory,the fragment’s terminal state and distributing area of different exploding height was obtained,the height of the largest lethal area was the optimal exploding height.Calculation shows in different trajectory conditions there is optimal exploding height for the largest lethal area;as the speed and attitude angle increase,the largest lethal area and its corresponding optimal exploding height increase.
