Aiming at the restriction of no-fly zone during the reentry of hypersonic glide vehicle, a reentry guidance method for avoiding no-fly zone based on IFDS algorithm is proposed . In longitudinal guidance, a predicor-corrector method is used to calculate the magnitude of bank angle. In lateral guidance, the current expected heading angle of the aircraft is calculated in a two-dimensional plane by the IFDS algorithm. Then a bank reversal logic is applied to determine the symbol of the bank angle based on the current expected heading angle. Finally, the feasibility of the algorithm to solve the no-fly zone avoidance problem is verified by a large number of simulations.
