Abstract This paper proposes an online entry trajectory planning based on predictor corrector algorithm that satisfies terminal constraints, path constraints and geographic for lifting-body vehicles. The vehicle is considered as a 3DOF point mass. A piecewise linear bank profile in the altitude-versus-velocity (H-V) plane used to project longitudinal heading angle corridor-based reversal logic designed satisfy simultaneously. solves problem of mismatch between range height lateral no-fly zone constraint. Simulation results with CAV-H model show proposed can generate trajectories satisfying multiple has certain robustness.
