Abstract

La présente invention concerne un dispositif d'alimentation en air de ventilation dans un rotor de turbine d'un moteur à turbine à gaz comportant un premier et un deuxième disques (11, 12) de turbine et une virole (14) en aval formant ensemble un tambour monobloc, le deuxième disque (12) de turbine comprenant des alvéoles usinées dans la jante (12J) pour loger les aubes (6) de turbine et les aubes étant retenues axialement par des segments (18 ; 18') de retenue axiale. Le dispositif est caractérisé par le fait qu'au moins un perçage (12P) est réalisé dans la virole (14) en aval de la jante (12J) mettant en communication l'intérieur du tambour avec au moins une partie des dites alvéoles, un passage (18P ; 18'P) étant ménagé dans les segments (18 ; 18').
