Abstract

The invention provides a wide-speed-range jet flow control aircraft. The wide-speed-range jet flow control aircraft comprises an aircraft body and wings arranged on the left side and the right side of the aircraft body, wherein flow separation restraining devices are distributed on a front edge of each wing in the spanwise direction of the wing and used for restraining flow separation on a surface of the wing; an adjustable nozzle circular rector control device is arranged on a rear edge of the outer side of each wing to provide rolling control for the aircraft; a binary jet flow thrust vector device is arranged in the middle of a rear end of the aircraft body, and pitching and yawing control in wide-speed-domain flight is carried out through the binary jet flow thrust vector device. According to the wide-speed-range jet flow control aircraft, a problem that the three-axis attitude control of an existing control-surface-free aircraft in a low-speed, high-attack-angle and high-subsonic-speed flight state fails is solved.

Description

technical field [0001] The invention belongs to the technical field of aviation systems, and in particular relates to a wide-velocity jet flow control aircraft. Background technique [0002] The aircraft without control surfaces uses pure jet control to replace the traditional mechanical deflection rudder surface, showing a variety of advantages, such as: (1) occupies less volume and weight; (2) equipment manufacturing and maintenance costs are lower; (3) mobile The microholes and slits on the outer mold line of the aircraft are removed to reduce the gap flow noise; (4) the stealth characteristics of the aircraft are improved when the aircraft is manipulated and trimmed. [0003] Some existing aircraft without control surfaces simply use different jet combinations of trailing edge circulation control wings to provide pitch, roll and yaw attitude control moments. When the aircraft flies at low speed and high angle of attack, the existing trailing edge circulation control tec...
