Abstract

Un ensemble aubagé pour turbine de turbomachine comprend une plateforme externe comportant, à une extrémité axiale, une surface transversale d'extrémité (82) et un dispositif d'étanchéité (100) s'étendant en saillie à partir de la surface transversale d'extrémité et comprenant au moins deux nervures d'étanchéité (102) s'étendant transversalement à un axe de l'ensemble aubagé et présentant chacune deux flancs respectifs (104A, 104B, 106A, 106B) qui, en section axiale, sont inclinés radialement et axialement dans une même direction par rapport à l'axe. Cette particularité confère de la souplesse à chacune des nervures d'étanchéité (102), ce qui permet de favoriser un contact surfacique entre les nervures d'étanchéité et une paroi radiale de stator en regard de laquelle la paroi transversale d'extrémité, et en particulier le dispositif d'étanchéité, sont destinés à être agencés.
