Abstract

Roue de turbine comprenant une pluralité de pales (14), chacune des pales présentant un profil (144), une plateforme (142) et une attache (140), un disque (12) à la périphérie duquel sont montées les pales (14), l'attache de chacune des pales étant engagée dans un logement (120) s'ouvrant à la périphérie du disque et s'étendant axialement entre deux faces opposées (128, 130) du disque, les logements étant séparés par des dents (121), et un dispositif de retenue axiale (16) des pales. Le disque comporte premier organe d'arrêt (126), et la plateforme de ladite pale comporte une projection (150) faisant saillie axialement au-delà de l'une des faces du disque. Ladite projection comporte un second organe d'arrêt (146). La projection axiale, le second organe d'arrêt et ladite face du disque forment une gorge orientée vers l'axe du disque (A), ladite gorge étant destinée à recevoir le dispositif de retenue axiale.
