Plasma flow control can significantly improve the aerodynamic characteristics of aircraft and power plant through plasma aerodynamic actuation, and this technology has already become a front subject in international aero- dynamics and aerothermodynamics fields. Status of overseas plasma flow control research is introduced briefly. Pro- gress of Air Force Engineering University in plasma shock flow control theory, plasma aerodynamic actuation char- acteristics, plasma based compressor stability extension and shock control is presented. Also, the important prob- lems in future are pointed out.
