Patent ID: 8579591

Claim:
A compressor impeller comprising: a hub having a radius; a plurality of main blades connected to the hub, wherein each of the main blades is equally spaced around the circumference of the hub, each of the main blades comprising: a suction surface formed in substantial conformance with normalized Cartesian coordinate values of X, Y, and Z set forth in Table 1; and a pressure surface formed in substantial conformance with normalized Cartesian coordinate values of X, Y, and Z set forth in Table 2; and a plurality of splitter blades connected to the hub, wherein each of the splitter blades is equally spaced around the circumference of the hub, and wherein each of the splitter blades is further equally spaced between two main blades, the two main blades being adjacent on the hub, each of the splitter blades comprising: a suction surface formed in substantial conformance with normalized Cartesian coordinate values of X, Y, and Z set forth in Table 3; and a pressure surface formed in substantial conformance with normalized Cartesian coordinate values of X, Y, and Z set forth in Table 4; wherein the normalized Cartesian coordinates, when connected by smooth, continuing arcs, form complete main blade and splitter blade shapes that are substantially matched by the main blade and splitter blade shapes of the compressor impeller.
