A gliding aircraft three-dimensional reentry guidance method based on analytical prediction

The invention discloses a gliding aircraft three-dimensional reentry guidance method based on analytical prediction. The method comprises the following implementation steps of: constructing a three-dimensional flight corridor taking a longitudinal lift-drag ratio, a lateral lift-drag ratio and energy as a standard frame by considering constraint conditions, directly designing a flight profile in the three-dimensional flight corridor based on a prediction model, designing a reasonable heeling overturning strategy, updating the flight profile, and tracking the flight profile to generate a heeling angle instruction and an attack angle instruction. The method is based on a high-precision analysis model; the aircraft target accessibility and the lateral maneuvering task requirements are comprehensively considered; A flight profile and an overturning strategy are directly designed in a three-dimensional flight corridor constructed by considering a plurality of constraint conditions; An attack angle instruction and a roll angle instruction are generated through profile tracking, so that the design of the three-dimensional reentry guidance method is completed, the integrity of dynamic information can be ensured, and the task adaptive capacity of the gliding aircraft under the long-distance large-range maneuvering condition is fully exerted.
