TURBOCHARGER WHEEL WITH SOUND CONTROL

摘要

A turbocharger wheel comprises a hub and a plurality of blades. The center of the hub mass and the quantum of the center of a mass of the blades are on a rotation axis. The blades are circumferentially spaced apart to be rotationally asymmetric. Each consecutive pairs of the blades is configured by a separation angle. A line perpendicular to the rotation axis and intersects with the rotation axis is configured to form a symmetry plane, and the separation angle is symmetrical across the symmetry plane.
