Abstract
A rotor wheel, particularly for compressors, including a rotor disc and a plurality of radially-projecting metal blades arranged along the periphery of the disc. A plurality of locating rings, formed predominantly of directionalized fibers, are provided, each locating ring being adjacent to all the blade roots and serving to resist centrifugal loads on the blades. An attachment ring formed predominantly of undirectionalized fibers surrounds the periphery of the rotor disc, and all the blade roots and locating rings are embedded in the attachment ring. The attachment ring serves to attach the blades to the rotor disc. Each blade root may have a T-shape and each locating ring engages over the cross bar of the T of each root. Alternatively, each blade root may have a hole accommodating a pin, and each locating ring engages over the pin of each blade root. Each blade root may have a plurality of sections, a single pin passing through holes in all of the sections of each root.
