FIELD: manufacturing technology.
SUBSTANCE: invention relates to centrifugal compressors and particularly to an impeller of a centrifugal compressor, and said impeller has a disc and blades attached to disc on front surface of disc. Point of intersection of rear edge and blade tail is additionally displaced by at least half thickness of disc forward as compared to blade tail on intermediate diameter (D)i of impeller, and point of intersection of rear edge and edge of blade is also shifted forward in comparison with edge of blade on intermediate diameter (D)i of impeller.
EFFECT: impeller with disc and blades attached to disc on front surface of disk.
