Control of flow separation by dynamic excitation of the free shear layer,d blowing through a narrow slot close to the leading edge of the airfoil. A small cavity below the slot was connected to a horn-driver providing periodic pressure fluctuations to drive the flow through the slot. The present research confirms the results of previous studies that the mechanism for

On Active Control of Boundary Layer Instabilities on a Wing,in a reduction of the viscous friction drag. One less known approach is the reduction of natural occurring instability waves, so called Tollmien-Schlichting-waves (TS-waves) of a laminar boundary layer by means of superposition with artificially excited canceling waves. For technical applications of
