摘要
The 3 degree-of-freedom equations of motion of an entry vehicle was built by using dimensionless negative energy as independent variable, and an improved rapid algorithm that generating landing footprint was proposed. The footprint was more accurate by using reverse bank angle strategy, and the boundary was more uniformity by improving interpolate method. The trajectory was smoother by the handle technique of the final constraints. It was validated by a waverider vehicle, and simulation results indicate that the landing footprint computed by the improved algorithm is more accurate and the trajectory is smoother.
