Abstract (en)

[origin: FR2863787A1] The rotor has a flange (38) parallel to an induced disc (36) and ring gear cooling fins (40), where each fin extends between a lateral side (48) of the disc and internal lateral side (50) of the flange. Some fins radially extend inside the rotor to form a series of fixation arms (62). An undercut (74) is formed between a lateral edge (58) of an axial end of the fin and the side (48) for forming a heat barrier.
