Abstract

L'invention concerne un ensemble rotatif pour turbomachine, comprenant un disque rotatif, des aubes, des plates-formes, un flasque (63) d'étanchéité s'étendant radialement entre les plates-formes (30) et le disque (16), en face aval de l'échasse (32) et du pied. Le flasque comprend radialement une partie sensiblement annulaire interne (66) et une partie sensiblement annulaire externe (64) en appui axial et radial l'une contre l'autre dans une zone du flasque radialement intermédiaire entre : - un bord périphérique radialement externe où la partie sensiblement annulaire externe (64) est engagée dans une gorge annulaire radiale des plates-formes (30), et - un bord périphérique radialement interne où la partie sensiblement annulaire interne (66) est axialement serrée entre, en amont, les dents du disque et les pieds d'aubes et, en aval, un anneau aval d'étanchéité (52).
