Abstract

La présente invention concerne un ensemble d'anneau de turbine comprenant 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 deux brides annulaires (32 ; 36), chaque secteur d'anneau (10) ayant une partie formant base annulaire (12) avec une face interne définissant la face interne de l'anneau de turbine et une face externe à partir de laquelle s'étendent au moins deux pattes (14 ; 16), les pattes (14 ; 16) de chaque secteur d'anneau (10) étant maintenues entre les deux brides annulaires (32 ; 36) de la structure de support d'anneau (3), caractérisé en ce que chaque patte (14 ; 16) des secteurs d'anneau (10) comporte une portion en saillie (140 ; 160) sur sa face (14a ; 16a) située en regard d'une des deux brides annulaires (32 ; 36), cette portion en saillie (140 ; 160) coopérant avec un logement (320 ; 360) présent sur la bride annulaire (32 ; 36), et en ce que chaque patte (14 ; 16) des secteurs d'anneau (10) comporte au moins une ouverture (15 ; 17) dans laquelle est logée une partie d'un élément de maintien (40a ; 40b) solidaire de la bride annulaire (32 ; 36) située en regard de ladite patte (14 ; 16), un jeu (J) étant présent entre l'ouverture (15 ; 17) de ladite patte (14 ; 16) et la partie de l'élément de maintien (40a ; 40b) présente dans ladite ouverture (15 ; 17), ledit élément de maintien (40a ; 40b) 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 (10).
