FIELD: manufacturing technology.
SUBSTANCE: impeller (46) includes hub (62) having an axis and direction of rotation, blades (60) extending from said hub. Each blade has downstream end (72), upstream end (68), leading surface (74) facing the direction of rotation of the hub, and trailing surface (76) facing opposite to the direction of rotation of the hub. Impeller (46) further includes secondary flow reducer (80) extending towards downstream end (72) and upstream end (68) of said at least one of impeller blades (60). Secondary flow reducer (80) defines first and second surfaces intersecting one of the leading surface and the trailing surface of the at least one of the impeller blades as well as a third surface between the first and second surfaces.
EFFECT: compressor impeller is disclosed.
