Abstract

There is proposed a bladed rotor (24) for a turbo-machine (10), the rotor having a rotational axis (X-X) and comprising a hub (26) defining a plurality of circumferentially spaced-apart slots (31) around its periphery. Each slot (31) slideably receives a root portion (29) of a respective rotor blade (27), the root portion (29) of each blade defining a radially inwardly open retaining groove (36) within which a respective region of a retaining ring (37) locates to retain the blades (27) in said slots (31). The retaining ring (37) also engages within a plurality of radially inwardly open hub grooves (34) formed around the hub (26). The retaining ring (37) engages each said hub groove (34) such that a radial gap (50) is defined between the retaining ring (37) and a radially outermost region (49) of each hub groove (34).
