Abstract

L'invention concerne un ensemble (200) pour turbomachine comprenant une roue à aubes (201) comprenant une aube (210), et un anneau de turbine (250) entourant ladite roue à aubes (201). Une aube (210) est munie d'au moins un élément d'étanchéité mobile entre une première position et une deuxième position dans lequel l'élément d'étanchéité mobile (215) est en contact avec une surface interne (251) de l'anneau de turbine (250). Au moins l'un parmi l'élément d'étanchéité mobile (215) et la surface interne (251) présente un matériau dit à faible friction. L'invention a également pour objet une aube (210) et une turbomachine (10)
