Flying wing aircraft has been increasingly used because of its high lift-drag ratio and superior steal performance. However, the deflection of the control surface increases the radar scattering area of the aircraft. In this work, a control method adopting jet circulation control and reverse jet control is proposed to control the flight attitudes for a flapless flying wing configuration. The wind tunnel force measurements were conducted to analyze the effectors of these two active flow control methods. Results show that jet circulation control can provide the regular and controllable rolling moment and pitching moment for the model, while the reserve jet control can provide the regular and controllable yawing moment. A flight test was conducted to investigate the attitude variation with the control signals of the active flow control actuator. The flight data indicate that the jet circulation control can control the pitching movement of the UAV. Despite the coupling of the lateral and directional control, the rolling movement and yawing movement can be controlled with jet circulation control and reserve jet control respectively.
