A planning algorithm for the near space maneuvering trajectory of the HTV (Hypersonic Technology Vehicle) is developed. Firstly, the coordinate system for trajectory planning and the motion equations of the vehicle are established. Then, the models of the constraint conditions considering fly-way points and no-fly zones are deduced. Further, the corresponding flight corridor and the trajectory planning algorithm are developed. Simulation results indicate that the lateral envelope of the near space maneuvering trajectory is above 3000km and the low-flight model makes the detection ability of radar largely deduced. In the multiple confrontation case with four TPY-2 radars, the planned near space lateral maneuvering trajectory can avoid all of the no-fly zones effectively and finally fly through the target point.
