On a compressor with compressor blades, a flow transition fixation mechanism ( 4 ) is provided on the suction side ( 2 ), approximately parallel to the leading edge ( 3 ) and upstream of the compression shocks acting upon the blade, which prevents the transition point from the laminar to the turbulent boundary layer flow from oscillating, thus suppressing oscillation of the compression shocks and their coupling effect with the natural frequencies of the compressor blades.
