非均匀初速度的战斗部静态飞散区设计

Design of Fragment’s Non-Average Original Speed in Warhead’s Static Flying Zone

针对防空导弹拦截高速目标时存在的战斗部破片动态飞散区变窄问题,提出一种非均匀初速度的战斗部破片静态飞散区设计方法,使战斗部前端破片静态飞散区至后端破片静态飞散区内的破片初速度具有逐渐递增的分布特征。通过仿真验证,该设计方法可使导弹拦截高速目标时的破片动态飞散区变宽,能覆盖更宽的引信启动散布区,有利于提高防空导弹拦截高速目标的引战配合效果。

When the anti-aircraft missile intercepts the highly speed target,the fragment′s static flying zone will be narrowing.For resolving this problem,a design method is presented:when the front of warhead uniform with missile′s intercepting direction.From front static flying zone to last static flying zone,a incremental change of fragment′s original speed is designed.By this method,a more broadly dynamic flying zone can be obtained.It benefits for dynamic flying zone matching with fuze burst zone,and a effect in intercepting the highly speed target can be improved.
