Abstract
A compressor for a turbocharger for use with an internal combustion engine includes a compressor wheel having a central hub having a centerline, a root portion, and an end portion. A plurality of blades is formed around the central hub. The plurality of blades includes a group of full-blades extending from the root portion of the central hub up to a maximum distance from the root portion along the centerline, the maximum distance being adjacent the end portion of the central hub. The plurality of blades includes a group of half-blades, the half-blades extending from the root portion of the hub to an area along the centerline that is between 60% and 65% of the maximum distance along the centerline. The plurality of blades is organized in repeating sets of blades arranged around the compressor wheel, each repeating set including at least one full-blade and at least one half-blade.
