The measurement of skin friction is presently recognized as a critical element of aerodynamic testing. Skin friction is necessary to characterize wall-bounded flows, to provide critical information necessary for computational simulations and to serve as a sensitive quantity for use in flow-control applications. The paper is aimed at presenting a new technique of precise skin friction measurement applied for a flat plate at the adverse pressure gradient corresponding to pressure distribution in the axial compressor.
