Abstract
The Approach and Landing (A&L) trajectory optimization is important for reusable launch vehicle (RLV) to deliver it to its landing site safely and reliably. And the trajectory should satisfy multi-constraints and path features. In this paper, the 3D dynamics of RLV in the A&L phase is introduced. and the the adaptive Gauss pseudo-spectral method (AGPM) is used to solve the A&L trajectory optimization problem. The adaptive method in GPM can improve the accuracy of the trajectory and accelerate convergence velocity of algorithm effectively. The simulation results of the typical RLV (X-33) demonstrate the feasibility of the trajectory optimization scheme which can let the RLV land securely.
