Abstract: Results of calculations and experimental investigations of characteristics of a supersonic high-pressure wide-chord stage of an axial compressor are presented. The influence of surface roughness on the characteristics of this stage are analyzed. A method of identification of aerodynamic flow parameters in the compressor duct is described.

Keywords: axial compressor, high-pressure wide-chord stage, three-dimensional calculation, stable operation, equivalent surface roughness, identification, compressor characteristic.
