Abstract To solve the problem of time cooperation reentry guidance for hypersonic gliding vehicles, a reentry guidance method based on dynamic angle of attack profile is proposed, which can realize the terminal time constraint. Firstly, the angle of attack profile and the height-velocity profile are determined by two parameters. The two profiles can ensure that the aircraft meets terminal state constraints and process constraints. The remaining range and time are predicted online by longitudinal guidance via iteratively correcting two parameters. Combined with the lateral heading angle corridor, the time-constrained entry guidance is implemented. The adaptability of the proposed method in different tasks is verified. The simulation results show that the method is effective to satisfy the time constraint and other terminal constraints.
