Optimization method of ballistic blast fragmentation warhead striking aircraft in aircraft shelter

为了评估弹道式杀爆弹打击掩蔽库飞机的经济性与可行性,以某典型飞机与单机/双机掩蔽库为研究对象,基于一/二次曲面拟合的思路,构建了飞机与掩蔽库的三维曲面模型;根据破片速度与位置模型,结合坐标系转换关系,给出了弹目交会算法;建立了飞机的毁伤树模型,得到了飞机毁伤概率计算方法;为了降低弹目交会计算量,提出了将目标区域网格化,网格点作为备选瞄准点的寻优策略,以及基于积分法的飞机平均毁伤概率计算方法;以全部飞机整体毁伤效果最优为目标,提出了基于改进粒子群算法的最小耗弹量与最优瞄准点寻优算法,并给出了打击方案优化方法;开展了杀爆弹对单机/双机掩蔽库飞机的打击方案优化仿真,仿真结果表明,低爆高、小CEP、多瞄准点组合打击等策略可有效降低最小耗弹量。

For evaluating the economy and feasibility about blast fragmentation warhead striking aircraft in aircraft shelter,taking a typical aircraft and single/double aircraft shelter as study objects,based on the thought of simple/quadratic surface fitting,the 3D surface models of aircraft and shelter are built.According to the velocity and position model of fragment,combined with the transformation relationship of coordinate system,the missile-target encounter algorithm is given.The ruin tree model of aircraft is constructed to calculate the ruin probability algorithm of aircraft.For reducing the computation of missile-target encounter,a mean ruin probability algorithm of aircraft based on integration method is proposed,which slices target area to grids and takes grids as alternative aim point.Taking maximum to entire ruin effect of all aircrafts as target,the optimizing algorithm to strike scheme about minimum missile consumption and find best aim point based on advanced PSO algorithm are proposed.The striking scheme optimizing about fragmentation warhead striking aircraft in single/double aircraft shelter is simulated.The result shows that,low blast height,small CEP,combination strike strategy with multiply aim points can reduce the minimum missile consumption effectively.
