Abstract (en)
[origin: EP0669451A1] The rotor assembly is composed of radial blades (1) encastred in the rotor disc (8). Composite material platforms (2) composed of a central beam (3) and cores (4) on either side are held in place between consecutive blade pairs. The cores have two external flanks (6) directed towards the blades which widen out radially. Substantial longitudinal play (7) exists between the blades and the platforms. Sealing lagging (15) which occupies the play is made from an envelope (16) formed with an internal face (17), carried against the flanks an external supple face (18) directed towards the blade surfaces and a internal radial heel (19). The lagging is formed from a long heavy beading (20) contained in the envelope.
