The uncertain factors, including atmospheric density, aerodynamic coefficients, and mass of aircraft, are likely to have a catastrophic impact on flight safety for hypersonic glide vehicles (HGVs). It is crucial for HGVs to quickly generate feasible gliding trajectories considering the impact of uncertainties, to execute complex flight tasks such as online target changing. A rapid trajectory planning method is proposed, which is based on the drag-acceleration-profile method employed during space shuttle entry flight. This method can efficiently generate a feasible trajectory while accounting for the influence of uncertain factors. Compared with traditional methods, the proposed method incorporates the influence of uncertain factors on the boundaries of the flight corridor. It establishes an uncertain flight corridor model, thereby ensuring the safety of the reference flight profile designed within this corridor under actual uncertain flight conditions; on the other hand, a simplified design approach is adopted for the reference flight profile, enabling the rapid generation of satisfactory profiles through straightforward parameter iteration or optimization. Simulations demonstrate that this method can efficiently plan gliding flight trajectories that meet safety requirements, exhibiting potential for online trajectory generation and maneuverability assessment.
