Abstract

L'invention concerne un ensemble rotatif pour turbomachine, comprenant : - un disque (10) ayant une périphérie externe présentant une alternance d'alvéoles (16) et de dents (18), - des aubes (12) s'étendant radialement depuis le disque (10) et dont des pieds (14) sont engagés axialement dans les alvéoles (16), des espaces appelés cavités d'alvéoles (20a) étant ménagés entre les pieds des aubes et les alvéoles, - des plates formes (22) s'étendant latéralement depuis les aubes (12) et agencées circonférentiellement bout à bout, de manière à former des espaces appelés cavités inter-aubes (26), - un flasque annulaire aval (34), comprenant une lèvre annulaire externe d'étanchéité (38) en regard des extrémités aval des plates-formes (22), Selon l'invention, le flasque annulaire aval (34) comprend en outre une lèvre annulaire intermédiaire d'étanchéité (48) en regard des faces aval des dents (18) du disque, radialement entre les cavités d'alvéoles (20a) et les cavités inter-aubes (26).
