Abstract (en)

A turbine engine rotor incorporates at least one disc (11) fitted with a composite annulus (18) fitted in the radial part closest to the innermost part of the disc. The annulus is lodged in a closed annular cavity arranged in an enlarged part (14) of the disc, in the form of a hub. The annular cavity is formed by an annular throat (16) machined in the enlarged part of the disc and closed by an annular metal plate (20) after the annulus is put in place. Independent claims are also included for : (1) a rotor disc incorporating the composite annulus; (2) the fabrication of the rotor disc.
