Abstract

La présente invention concerne un rotor (1) de turbine comprenant un disque de rotor (2), muni à sa périphérie d’une pluralité d’alvéoles axiales (23) de réception d’un pied (30) bilobé d’une aube (3), chaque alvéole (23) comprenant une cavité radialement interne (232) et une cavité radialement externe (231). Ce rotor est remarquable en ce qu’il comprend un anneau (4) de retenue axiale des pieds d’aubes et un flasque annulaire (5), l’anneau (4) comprenant une partie radialement interne munie d’échancrures (43) et étant disposé contre la face amont (21) du disque (2), de sorte que chacune de ses échancrures (43) soit située en face d’une alvéole (23) du disque (2), le flasque (5) étant fixé contre la face amont de l’anneau (4), ménageant un espace (E) avec ledit disque (2) et comportant au moins un orifice d’admission d’air (54) qui débouche dans ledit espace (E) et en ce que chaque aube (3) comprend une gorge (33) de réception du bord circonférentiel externe (46) dudit anneau (4).
