Results of measurement of flow parameters in a stage of the axial compressor at radial, crescent and sabre vanes of the outlet stator are presented. Essential influence of a circumferential bowing of the stator vanes on time-averaged rotor flow parameters is established at preservation of the effects connected to influence of a mutual tangential position of stators on the rotor blade pressure pulsations and generated noise.
