Abstract
To address the reentry guidance problem of a lifting reentry vehicle that simultaneously satisfies typical path constraints, terminal conditions and no-fly zone constraints, a trajectory planning and guidance method based on artificial potential field and drag acceleration profile is proposed. In the longitudinal profile, a drag acceleration profile tracking guidance is used to calculate the bank angle magnitude that satisfies the flight range. In the lateral profile, an improved artificial potential field method is used to obtain the heading angle corridor, which can determine the sign of bank angle and guide the lifting reentry vehicle to avoid the no-fly zone and sudden threats. The results show that the proposed algorithm is effective to address the reentry guidance problem with no-fly zone constraints.
