Aiming at the optimization of reentry trajectory for hypersonic glide vehicles, the coordination strategy of angle and time based on the hp-adaptive Radau pseudospectral method is proposed. After establishing the kinematics model, the hp-adaptive Radau pseudospectral method is used to transform the optimal control problem into a nonlinear programming problem. Then the strategy based on virtual target points and extended variables is proposed to realize the coordinated flight of multiple vehicles. The results show that this method can quickly generate optimal trajectories satisfying complex constraints and realize the coordination of angle and time.
