Abstract: An in-depth understanding of airfoil dynamic stall, combined with effective flow control means, is of great significance for solving the aerodynamic problems such as high resistance and high bow torque caused by the dynamic stall of helicopter and wind turbine blades. In this paper, the characteristics and hazards of airfoil dynamic stall are firstly introduced, and then the effects of reduced frequency, Reynolds number, Mach number, and airfoil profile on dynamic stall are analyzed. On this basis, the common dynamic stall flow control methods and their research progress are summarized. The plasma aerodynamic actuation is easy to produce fast and controllable wide-band aerodynamic actuation, which has potential in the field of dynamic stall control. The concept of dynamic stall control with plasma aerodynamic actuation and the principle of flow control are introduced in detail, and the progress of plasma actuation in airfoil dynamic stall control in recent years is summarized.

Key words: dynamic stall, influence factors, flow control, airfoil, plasma actuation
