Abstract : Direct measurements of the wall shear stress have been made at a point on three thicknesses of an elastic compliant surface. Approximately 8% Cf reduction was measured on each surface. Observations of the surfaces' motion showed that they responded to the microscale turbulent eddies. At higher forcing the onset of various surface wave phenomena were observed. Keywords: Compliant surfaces, Drag reduction, Skin friction, Boundary layers.
