Abstract
A compressor wheel for a turbocharger includes first, second and third pluralities of blades formed around a central hub. Each of the second plurality of blades is disposed between adjacent blades from the first plurality of blades and extend a shorter distance than the first plurality of blades along the centerline of the central hub. Each of the third plurality of blades is disposed between adjacent blades from the first and second pluralities of blades, and extends a shorter distance than the second plurality of blades along the centerline of the central hub. Together, the blades are separated in sets, each set including a blade from each of the first, second and third pluralities in order with respect to any radial location around the compressor wheel as the compressor wheel rotates.
