Abstract

Numerical investigations with the DLR TAU Code demonstrate that an actuated back-flow flap on the suction side of an OA209 helicopter airfoil is able to improve the dynamic stall behavior. When the flow begins to stall, the flap is extended which interferes with the back-flow. This weakens the dynamic stall vortex and consequentially the peak in the pitching moment peak is reduced.
