摘　　要：针对升力式飞行器在强干扰环境下集结的问题,提出一种可达时间快速计算方法以及集结轨迹规划方法。在满足平衡滑翔条件的前提下,提出能量航程剖面上最快到达与最慢到达对应的两种轨迹模式,推导了两种轨迹满足的条件,基于双层牛顿割线法,构建一种可达时间实时求解方法,形成了升力式飞行器集结轨迹实时规划方法。仿真结果表明,提出的集结轨迹规划方法能够完成未知强干扰作用下升力式飞行器的实时集结轨迹规划。A kind of fast reachable time calculation method and gathering trajectory planning algorithm are proposed to solve the assemble problem of lift vehicles under strong interference.Based on the double-layer Newton Secant method,two kinds of trajectory modes on the energy range profile corresponding to the fastest and slowest arrival are introduced,and a real-time reachable time calculation method is proposed.The real-time planning algorithm for the assemble trajectory of lift vehicles is constructed.The simulation results show that the proposed method can achieve real-time gathering trajectory planning of lift vehicles under unknown strong interference.
