The object of the study was a centrifugal compressor stage with axial-radial unshrouded impeller and an inlet guide vane. The results of experimental studies of a centrifugal compressor stage on the regulation modes by throttling on discharge, changing the rotor speed and changing the swirl of the flow in front of the impeller by turning the blades of the inlet guide vane are presented. Ranges of operating modes from the surge limit to maximum compressor capacity were established.
