Abstract (en)

A turbocharger turbine wheel (10; 20; 30; 40) includes a hub (13; 23; 33; 43)and a plurality of blades (12; 22; 32; 42). Both the center of mass of the hub and the center of mass of the plurality of blades are on an axis of rotation. The blades are circumferentially spaced such that they are rotationally asymmetric. Each consecutive pair of blades is characterized by a spacing angle (301). A line that intersects with and is normal to the axis of rotation defines a plane of symmetry, and the spacing angles are symmetric across the plane of symmetry.
