Abstract

The invention discloses a lift aircraft high-dynamic downward-pressing section guidance method. The steps include: calculating downward-pressing section guidance force, and calculating an downward-pressing section instruction according to the guidance force; and by tracking the downward-pressing section instruction, controlling flight of the lift aircraft in a downward-pressing section process. The lift aircraft high-dynamic downward-pressing section guidance method realizes high-speed downward-pressing section guidance of the aircraft, and solves the problem of strict constraints on downward-pressing section termination height, angle of inclination, lateral position and the like.

Description

technical field [0001] The invention relates to the field of aerospace, in particular to a guidance method for a high dynamic down-pressure section of a lift-type aircraft. Background technique [0002] The flight process of the lift aircraft generally includes the initial re-entry stage, the gliding stage, and the downward pressure stage. Very large overload and dynamic pressure, and due to the limitations of the aircraft structure and other systems, there are strict requirements on overload and dynamic pressure, and for the lift-type aircraft in high-speed aircraft, it is different from the axisymmetric aircraft, and the lift-type aircraft needs to turn over 180 Only when turning over at a large angle of attack can the downhill flight process be realized, and the corresponding height, lateral position, inclination angle, flight range and other constraints must also be met at the end of the downhill section. [0003] Existing guidance methods are mainly used for the downst...
