中程空地导弹下滑弹道的设计方法探优

The Optimization of Dexcending Ballistic Trajectory Design Method

针对中程空地导弹下滑段飞行的特殊性与复杂性,综合各方面的因素,设计了一种基于等弹道倾角转指数规律的下滑弹道方案,通过控制惯导垂直速度实现等倾角快速直线下滑,然后转指数规律曲线下滑平稳过渡到平飞段,数字仿真证明这种方法合理可行,能满足导弹战技指标的各项要求,且精度高,易实现,具有较高的实用价值。

According to the particularity and complexity of middlerange airtoground missile's descending process,this paper provided a descending ballistic trajectory scheme based on the method which let the missile first descend quickly according to fixed obliquity,then turn to exponential law for smooth transition to cruise process.This descending method can be realized by controlling the vertical velocity of inert guide system.Digital simulation shows that this descending method is reasonable and feasible,and can meet all kinds of request for missile design scheme,and have many strongpoint such as better precision,easy realizatio,and great applied value.
