Experimental data analysis for testing centrifugal compressor stage on control modes by the rotor speed and the turning angle of the inlet guide vane blades changing was completed. The attack angles distribution in inlet section of the impeller along the blade height was received. A major difference in the attack angle from the head to the periphery is found to affect the polytropic efficiency stage. Recommendations for improving the regulating mechanism of the inlet guide vanes unit were given.
