Dynamic stall control over a rotor airfoil based on AC DBD plasma actuation

open access: yesAdvances in Aerodynamics, 2021
At present, the control capability of dielectric barrier discharge (DBD) plasma actuation covers the flow velocity range of helicopter’s retreating blades, so it is necessary to extend it to the dynamic stall control of rotor airfoils.
