Abstract
The transient processes of stall growth and removal on a rigidly mounted aerofoil have been investigated experimentally using sound to control the aerofoil stall. The dynamic stall was similar to that on a pitching aerofoil and included the downstream passage of pressure perturbations across the aerofoil chord during stall and unstall. These delayed the normal force response to the changing flows on the aerofoil. The maximum frequency at which the complete unstall-stall cycle could be driven acoustically corresponded to the upper frequency limit of torsional stall flutter data for axial compressors.
