Abstract (en)
[origin: EP0370899A1] A turbo-engine rotor disc (1) is equipped with blades (3) associated with separate platforms (11) comprising a plate (12), each axial end of which is connected to a foot (24, 25) for fastening to the disc (1), interacting with a cylindrical bearing surface (7, 8) formed on the rim of the disc. At least one of the feet (24) is associated with a clip (27) of C-shaped cross-section which fixes it to a tooth-shaped element (4) of the disc (1), axial locking being obtained by means of a flange (30) of an adjacent element (15) of the said rotor. <IMAGE>
