Abstract (en)
[origin: WO2010076493A1] The invention relates to a turbine wheel including: a plurality of vanes (20), a rotor (10) with a disc (12) having a periphery on which the vanes are mounted, each vane including a blade (22) with a base connected to a platform (24) bearing an attachment (26) inserted into a recess opening at the periphery of the disc and extending axially between two opposite surfaces of the disc, the recesses being separated from each other by disc portions that define teeth (16), and a flange (40) for axially retaining the vanes on the disc, including a retaining flange (40) provided on one side of the disc. On the other side of the disc, the disc teeth include radially protruding raised patterns (18) defining abutments axially bearing on the raised patterns (28) formed under the platforms of the vanes and recessed relative to the side surfaces of the attachments provided on the second side of the disc, and the side surfaces of the attachments of the vanes and of the disc on the periphery thereof are located substantially in the same plane.
