Abstract

The invention discloses an aircraft three-axis attitude control system and method based on active flow control. A flying wing layout aircraft is used as an application carrier, and various active flowcontrols such as jet thrust vector, circulation control and reverse blowing are cooperatively used, so that three-axis attitude control of the aircraft in pitching, rolling and yawing directions is realized, and the maximum control moment which can be generated by a traditional control surface is reached or even exceeded. The system has the advantages that the structural arrangement is simple, adverse effects of engine shutdown and the like on active flow control are avoided, and the reliability of the system is improved. The response speed of the active flow control is higher than that of control surface control, and the maneuvering characteristics of the aircraft can be effectively improved.

Description

technical field [0001] The invention relates to an aircraft control system and method, in particular to an aircraft three-axis attitude control system and method based on active flow control. Background technique [0002] Conventional fixed-wing aircraft rely on the rudder surface for flight attitude control, but the traditional rudder surface leads to complex fixed and moving mechanisms inside the wing, high design difficulty, heavy structural weight, reduced stealth performance, increased maintenance difficulty, and affected The reliability of the control system; the frequent movement of the mechanical structure is prone to fatigue fracture, the actuating mechanism may be deformed and stuck, and there are certain safety hazards; the deflection of the rudder surface will bring additional resistance and reduce the flight performance. Conventional flight control methods can no longer meet the performance requirements and development needs of current aircraft, so new control m...
