基于终端毁伤的可瞄准战斗部优化设计

为对付多种不同的空中目标，实现战斗部破片的可控飞散，根据可瞄准战斗部的结构特点建立了弹体坐标系，基于引制一体化技术提出了可瞄准战斗部侧向攻击和前向拦截目标的单发杀伤概率计算模型. 根据可瞄准战斗部在导弹内的装配特点，初步优化了战斗部的设计参数，在此基础上，选择不同的典型目标，采用蒙特卡洛法分别研究了可瞄准战斗部的破片初速、破片飞散角和破片有效数量等主要性能参数对导弹终端毁伤效能的影响，基于终端毁伤效能的研究对可瞄准战斗部进行了优化设计，该优化过程对可瞄准战斗部的设计具有一定的参考价值. 

Optimal Designs of a Gimbaled Warhead Based on Kill Probability of Missile

In order to kill different types of airborne targets, gimbaled warhead was designed to fire the fragments in the target direction and the missile coordinate system was established. Based on guidance integrated fusing and the two encounter concepts of side-attack target and forward-intercept target at endgame, the formulas of kill probability of one-missile to one-target were developed, and the warhead basic parameters such as fragment spray angle, fragment ejection velocity and fragment number were designed depending on configuration features of the warhead space layout in missile skin. Then, by selecting the different typical target, the effects of the design parameters on the kill probability were studied by using Monte-Carlo method, and the optimizations of the design parameters of the warhead were obtained based on these studies. The optimization process will be of a certain reference value in engineering design of gimbaled warhead.
