高超声速滑翔飞行器具有再入走廊狭窄、机动能力强和再入制导实时性要求高的特点。针对再入走廊多约束问题,分析了不确定因素下再入走廊约束转化成倾侧角约束的问题。利用禁飞圆切线法预测总航程,结合航向角误差走廊控制横向突防轨迹,设计了三维耦合突防轨迹在线生成方法。仿真结果表明,迭代2~3次即可获得满足约束条件的大范围机动再入轨迹。
Hypersonic gliding aircraft with re-entry corridor narrow, strong maneuverability and re-entry guide real-time requirements of high characteristics. Aiming at the multi-constraint problem of re-entry corridor, the problem of re-entry corridor constraint transformed into tilting angle constraint under uncertainty is analyzed. By using the no - fly circle tangent method to predict the total range and combining with the trajectory of the lateral corridor control error of the heading error corridor, a method of on - line generation of three - dimensional coupled penetration trajectory is designed. The simulation results show that a large-scale maneuver re-entry trajectory satisfying the constraints can be obtained by iterating two or three times.
