Abstract

A piecewise guidance strategy of unpowered auto-landing for reusable launch vehicle is proposed based on non-trajectory tracking methods. According to the auto-landing constraints and the shift requirements of two phases, which are the terminal area energy management phase and the approaching and landing phase, vertical and horizontal piecewise trajectories are designed, each piece of trajectory is matched with a guidance law, and the drag panel control strategy is presented to solve the maximum dynamic pressure control problem. Simulation shows that the constraints can satisfy the restricting conditions with the advantages of great robustness under the interference environment and easy engineering.
