Keywords: vortex breakdown, active flow control, maneuverability

Water tunnel experiments were conducted on a 65deg delta wing/centerbody model to explore the effectiveness of a moveable blowing along the leading edge, wing surface or centerbody on the vortex breakdown. The positive feedback implicit in the breakdown process is exploited to minimize the required control power. A novel concept is proposed to enhance the maneuverability and controllability of advanced air vehicles.
