In order to reduce the time required of avoiding the no fly zone in the process of trajectory planning for hypersonic cruise vehicle, and realize the real-time for cruise trajectory planning, a real-time trajectory planning method of combined A* search algorithm and geometric curve planning method is proposed. The same structure of search unit in A* algorithm is changed to anomalous structure. By the advantage of search speed of A* algorithm, and combined with the geometric curve planning method, the rapid trajectory planning method based on geometric curve and A* algorithm of anomalous structure is formed. The results show that the trajectory, which can effectively avoid the no fly zone can be obtained by using this method. This method can also obtain flight commands, and can realize the real-time requirements of trajectory planning.
