ABSTRACT:
A centrifugal compressor (10/110) or a centripetal turbine (76) having coaxially aligned, relatively rotatable rotors (12,112,212/14,114,214) mounting a plurality of blades (30,32,34,36,38/130/230) having variable radial extension from a central axis (15). The blades closer to the center of rotation of the rotors are operated at high speeds so to maximize their gas treating effect while rotating the larger diameter blades (40,42,44/132,232) at lower speeds commensurate with their stress capabilities.
