Plasma flow control is a hot topic of aerodynamics in recent years. Papers on plasma flow control are also fast rising in China. The characteristics of plasma aerodynamic actuation generated by dielectric barrier discharge, arc discharge and sliding discharge were studied widely. Separation control on airfoil, compressor cascade, bluff body and slender conical forebody using plasma aerodynamic actuation was investigated mostly. Shock wave control and compressor stability extension using plasma aerodynamic actuation were also performed. In order to improve the separation control authority, a new principle of "plasma-shock-based flow control" was put forward.
