Abstract

Un ensemble d'anneau de turbine comprend une pluralité de secteurs d'anneau (10) formant un anneau de turbine (1) et une structure de support d'anneau (3) comportant deux brides annulaires (32, 36). Chaque secteur d'anneau a une face interne (12a) définissant la face interne de l'anneau de turbine et une face externe (12b) à partir de laquelle s'étendent des pattes (14, 16). Les pattes (14, 16) de chaque secteur d'anneau (10) sont chacune maintenues en butée contre plusieurs éléments de maintien (19, 20, 21) solidaires de la structure de support d'anneau (3). Les pattes (14, 16) de chaque secteur d'anneau (10) sont en outre reliées à ladite structure de support d'anneau (3) par un système à ressort (40) apte à maintenir les pattes en butée contre les éléments de maintien, chaque système à ressort exerçant sur un secteur d'anneau une force de traction ou de poussée orientée dans une direction radiale (DR) de l'anneau de turbine.
