Abstract
We study the influence of the flow induced by a plasma actuator on the wing-tip vortex generation. A wing model with the plasma actuator is set inside the wind tunnel and the velocity components are measured by using a PIV system. The plasma actuator is set on the suction side of the wing model. By changing the induced flow direction, i.e., either blowing or suction, the starting position of the wing-tip vortex generation and the position of the vortex core are changed. Especially, in the case of blowing, the plasma actuator has a significant impact on the wing-tip vortex generation: its starting position is shifted downstream.
