摘要

The sleeve (102) has a main body (104) conforming to an inner surface of two directly consecutive platforms (46). The platforms are respectively placed in bases of two blades (34) of a rotor (20). The main body comprises a mechanical axial retention part i.e. strip (106), cooperating with a mechanical axial retention part i.e. groove (108), of a pin (66) of a downstream flange (60) to axially retain the flange towards upstream. The strip is radially projected from the main body towards interior or exterior of the sleeve.
