Abstract
There is proposed a bladed rotor for a turbo-machine, the rotor having a rotational axis and including a hub defining a plurality of circumferentially spaced-apart slots around its periphery. Each slot slideably receives a root portion of a respective rotor blade, the root portion of each blade defining a radially inwardly open retaining groove within which a respective region of a retaining ring locates to retain the blades in said slots. The retaining ring also engages within a plurality of radially inwardly open hub grooves formed around the hub. The retaining ring engages each said hub groove such that a radial gap is defined between the retaining ring and a radially outermost region of each hub groove.
