Abstract: Delta wings, being widely used in modern fighters, face aerodynamic problems such as vortex breakdown at large angles of attack. As a new type of active flow control technique, plasma aerodynamic actuation shows significant potential in the control of vortex flows of delta wings because of its fast response, simple structure, wide frequency band and convenience for closed loop control. In this paper, the principles of Dielectric Barrier Discharge (DBD) plasma aerodynamic actuation and its applications in the control of leading-edge vortices over delta wings are reviewed. The effect of DBD plasma actuation on flow control is analyzed in terms of the incoming flow condition, the geometry of experimental model and actuation parameters. Combining with the evolution characteristics of flow field at different actuation frequencies, the mechanism of flow control is analyzed. Finally, the future theoretical research and engineering application of delta wing vortex control are expounded.

Key words: plasma actuation, dielectric barrier discharge, flow control, delta wing, leading-edge vortex
