Abstract:

The virtual rudder surface aircraft by circulation control instead of the mechanical rudder surface exhibits performance advantages in short-distance take-off and landing, high stealth, long range and maneuvering flight, and other aspects, meaning significantly for future research on rudderless flying wing configurations. We systematically summarize the research progress of circulation control technology at home and abroad, and clarify the development trend of virtual rudder flight control. The lift characteristics of the GACC airfoil with different momentum coefficients and angles of attack, and the aerodynamic characteristics of single and double jets are introduced. The principle of circulation control to improve lift and form “virtual rudder surface” is described. The moment characteristics of the SACOON platform in roll, pitch and yaw directions verify better control effect of the virtual rudder surface than that of the mechanical rudder surface. The concept and design ideas of virtual rudder surface aircraft are presented from four main aspects: circulation control airfoil, aerodynamic layout, jet actuation system, and jet flight control system. With focus on the problems and solutions in the air intake system, rudder efficiency, integrated design, safety and adaptability, the engineering application of virtual rudder aircraft is promoted. This review provides a theoretical reference for the application of the circulation control technology to rudderless aircraft in the future.
