Abstract

L’invention a pour objet un ensemble rotatif portant des aubes, destiné à être entouré par une portion de carter de turbomachine portant des éléments d’étanchéité abradables, cet ensemble comportant un disque (19) portant des aubes (18), chaque aube (18) s’étendant radialement par rapport à l’axe de rotation (AX) du disque (19) depuis un pied par lequel elle est solidarisée au disque (19) jusqu’à un sommet (22). Cet ensemble comporte un anneau (23) coaxial au disque (19), cet anneau (23) comportant pour chaque aube (18) une ouverture (29) dans laquelle est engagé un sommet d’aube (22) de manière radialement coulissante, l’anneau (23) étant destiné à longer les éléments d’étanchéité abradables portés par le carter.
