摘要
Abstract
The reentry trajectory optimization of a variable-configuration vehicle(VCV)is studied.A surrogate model is established for quick prediction of vehicle aerodynamics at different deformation and flight conditions.The time histories of deformation,angle of attack and bank angle are all taken as trajectory optimization variables,and the performance of the VCV in landing coverage area and the maneuverability to avoid obstacles are quantitatively studied.Simulation results show that compared with the fixed-configuration vehicle(FCV),the VCV can achieve the optimal morphing in addition to the optimal control along the reentry glide trajectory,thus leading to better reentry trajectory performance.关键词
