摘要
Abstract
For the planning problem of constrained reentry trajectory，an analytical method of planning reentry trajectory based on quasi-equilibrium gliding was proposed. In the longitudinal profile planning， based on the quasi-equilibrium gliding condition , the analytic formulations of the relevant parameters such as altitude，speed ,drag acceleration，angle of attack，and tilt angle，etc.，were constructed with respect to the rest range，and the altitude-range space constrained flight corridor was established. In the horizontal profile planning, an analytic planning method based on the horizontal and vertical multiple functions was used in the effective solution of avoidance of the no-fly zone. Via the above algorithm，the complex constrained reentry trajectory planning problem can be transformed into a simple analytical calculation, which greatly improves the speed and reliability of trajectory planning. The simulation results of CAV-H show that the proposed trajectory planning algorithm is fast，smoothly，accurately and elegant，and the algorithm can be implemented easily in engineering.关键词
