Abstract (en)
[origin: EP1855011A1] The assembly has a disk (2), and a set of vanes (6) mounted on the disk, where each vane has a blade (14) comprising a leading edge (20) and a leakage edge (22) circumferentially shifted from the edge (20). A vane foot comprises an upstream carrier surface (32) and a downstream carrier surface (34) that is located at the level of a side of the edge (22) of the blade. The disk has a circumferential slot (10) in which the vane foot is retained. The surface (34) is shifted circumferentially from the surface (32) along a given shifting direction (42), for each vane.
