Abstract
With combined numerical and experimental investigations of the dynamic stall process on refreating helicopter rotor blades new insight into the complex unsteady flows involved have been achieved recently. With these new experiences in mind it is of increasing interest to suitable influence the flow. i.e. by dynamic airfoil deformation. The present paper describes first steps towards an improvement of the dynamic stall effects with respect to the time-dependent flows and overall forces by both numerical and experimental tools.
