瞄准式战斗部是防空导弹提高战斗部杀伤威力的重要发展方向。根据不同弹目交会条件调瞄准战斗部的最佳起爆延时时间,可以提高防空导弹对目标的毁伤能力。文中建立了弹目交会模型和最佳起爆延时的计算模型,分析了影响最佳起爆延时的因素。仿真结果表明,最佳起爆延时不仅与交会条件有关,与随动系统的工作位置也有关。因此,必须确定瞄准式战斗部的最佳起爆延时才能有效击毁目标。

Aimed warhead is an important tendency for air-defense missiles to enhance damage effect. The damage effect by which air-defense missile kills the target can be improved by regulating the optimal delay time of aimed warhead in different encounter conditions. In the article, the encounter model and the optimal denotation delay calculation model were built. The factor impacting the optimal denotation delay was analyzed. The simulation results demonstrate that the optimal denotation delay is not only related to encounter conditions, but also related to the servo system positions.
