Abstract

Un ensemble d'anneau de turbine comprend une pluralité de secteurs d'anneau (10) en matériau composite à matrice céramique formant un anneau de turbine (1) et une structure de support d'anneau (3) comportant une première et une deuxième brides annulaires (32, 36), chaque secteur d'anneau ayant des pattes (14, 16). La première patte (14) de chaque secteur d'anneau (10) comporte une rainure annulaire (140) dans laquelle est logée une saillie annulaire (34) de la première bride (32), un jeu (J1) étant présent à froid entre la saillie annulaire (34) et la rainure annulaire (140). La deuxième patte (16) de chaque secteur d'anneau (10) est reliée à la structure de support d'anneau (3) par un élément de maintien élastique (50). la deuxième patte (16) de chaque secteur d'anneau (10) comporte au moins une ouverture (17) dans laquelle est logée une partie d'un élément de maintien (40) solidaire de la deuxième bride annulaire (36) de la structure de support d'anneau (3), un jeu (J2) étant présent à froid entre l'ouverture (17) de la deuxième patte (16) et la partie de l'élément de maintien (40) présente dans ladite ouverture, ledit élément de maintien étant en un matériau ayant un coefficient de dilatation thermique supérieur au coefficient de dilatation thermique du matériau composite à matrice céramique des secteurs d'anneau.
