Abstract

Disque (36) de rotor pour une turbomachine, le disque (36) s’étendant circonférentiellement autour d’un axe et comportant une pluralité d’alvéoles (44) configurées pour recevoir des pieds d’aubes (48) et chaque alvéole (44) comportant une paroi radiale amont (54) configurée pour bloquer axialement le pied d’aube (48) dans l’alvéole (44), chaque alvéole (44) étant reliée à une surface amont (74) du disque (36) par un canal de ventilation (76) de l’alvéole (44), le canal de ventilation (76) comportant un orifice d’entrée (78) qui débouche sur la surface amont (74) du disque (36) et un orifice de sortie (80) qui débouche dans l’alvéole (44). Ensemble d’un tel disque (36), d’une pluralité d’aubes (38) et d’un anneau de retenue aval (40) et turbomachine comprenant un tel ensemble. Figure pour l’abrégé : Fig. 3
