Abstract
For the maneuvering trajectory planning of hypersonic gliding vehicles under complex constraints, the traditional dynamics methods are complex, and difficult to optimize the control variables to maximize the maneuvering potential of the vehicle. Inspired by the path planning method of low-speed unmanned aerial vehicles, a trajectory planning method combining geometry and dynamics is proposed. Firstly, the feasibility of the method is verified theoretically, the coupling point between the two methods is established, and the information transmission process of joint planning is clarified. Secondly, according to the actual flight, the minimum cost function with angle as the parameter is designed, so that the trajectory search process can meet the complex constraints. The simulation shows that under the premise of rapid trajectory planning, the proposed method can more fully control the change of bank angle and reduce the number of flips, which is conducive to the stability of the whole flight process.
