Abstract

L'invention concerne un ensemble pour turbomachine s'étendant suivant un axe X, comportant une pluralité d'aubes s'étendant radialement entre une paroi longitudinale externe et une paroi longitudinale interne définissant une structure annulaire, au moins une des parois longitudinales comportant une pluralité de secteurs d'anneau, les secteurs d'anneau étant juxtaposés et assemblés pour former ladite structure annulaire, l'ensemble comportant en outre un dispositif d'étanchéité inter-secteurs configuré pour assurer l'étanchéité au point de jonction de deux secteurs d'anneau, le dispositif d'étanchéité comportant deux languettes montées dans des rainures et présentant un degré de liberté en flexion, l'extrémité d'une des languettes étant en contact avec le corps de l'autre languette.
