摘要
从高超声速滑翔飞行器协同任务需求出发,针对复杂再入环境下的轨迹规划问题,提出一种集群再入的协同轨迹规划方法。建立飞行器集群的再入动力学模型,基于控制量与再入走廊约束设计了一种纵向轨迹控制方案,以减缓轨迹求解时的振荡问题,提高轨迹求解的可行性。在此基础上,提出两种协同形式下的轨迹规划方案,根据飞行器集群的任务需求及滑翔能力分析结果完成协同时间的决策,利用hp自适应伪谱法规划出满足禁飞区和时间约束的协同轨迹。仿真结果表明,所提方法在不同任务场景下均能规划出满足约束条件和协同时间的三维轨迹,对高超声速滑翔飞行器协同规划研究具有一定参考价值。
Starting from the cooperative mission requirements of hypersonic gliding vehicles,a cooperative trajectory planning method for cluster re-entry was proposed to address the trajectory planning problem in complex re-entry environments.The re-entry dynamics of a cluster of vehicles was modelled,and a longitudinal trajectory control scheme was designed on the basis of the control volume and re-entry corridor constraints.This approach aimed to mitigate the oscillation problem during trajectory calculation and improve the feasibility of trajectory solution.On this basis,a trajectory planning scheme under two forms of cooperation was proposed,which completed the decision of cooperative time according to the mission requirements and the gliding capability analysis results of the aircraft cluster,and utilized the hp adaptive pseudo-spectral algorithm to plan the cooperative trajectory that satisfies the no-fly zone and time constraints.Simulation results show that the proposed method can plan 3D trajectories that satisfy the specified constraints and coordinated time under different mission scenarios.This has significant reference value for the cooperative planning research of hypersonic glider vehicles.
