Abstract

The invention discloses a bank-to-turn overturn guidance method of a lift aircraft. The method comprises: determining a horizontal restrain corridor of the aircraft in a gliding flight process; according to the current horizontal position, horizontal speed, and forecast time of the aircraft, determining a forecast horizontal position of the aircraft; according to the determined horizontal restrain corridor and the forecast horizontal position of the aircraft, determining overturn of a heeling angle instruction; and according to the heeling angle instruction, obtaining a heeling angle guidance instruction. Using the method can effectively prevent problems of deviation of a target attack direction caused by excessive maneuvering, and excessive overturn number in a gliding process of the aircraft.

Description

technical field [0001] The invention relates to the technical field of lift-type aircraft guidance, in particular to a method for guiding a lift-type aircraft by tilting, turning, and flipping. Background technique [0002] The lift-type hypersonic reentry vehicle is a new type of vehicle in the field of aerospace. Due to the shape of the lifting body, the lift-type hypersonic reentry vehicle generally adopts a banked turn (BTT) method with a sideslip angle of 0°, and a large-scale maneuver is realized through a large roll of the body, which can greatly improve maneuverability and hit accuracy. This type of aircraft needs to meet strict process constraints such as heat flow, overload, and dynamic pressure during the gliding reentry process, and at the same time, it also needs to meet the constraints of terminal speed, terminal height, longitudinal range, transverse range, and velocity deflection angle at the end point of the glide. , in order to achieve high-speed and accu...
