Abstract (en)
[origin: WO2011018425A1] The present invention relates to a vibration-damping shim (10) to be positioned between a platform (12) of a fan blade (6) and a fan disk (2), the shim being provided with a radially outer surface (18) fitted with plates (16a, 16b) contacting the fan blade platform, as well as a radially inner surface (20) formed by an upstream surface (22) to be opposite the disk, and a downstream surface (24) separated from the upstream surface by a discontinuity (26). According to the invention, the upstream surface (22) has an area (101) projecting radially inward, originating remotely from the upstream end (22a) thereof.
