Abstract

Ensemble d'anneau de turbine (10) comprenant une pluralité de secteurs d'anneau (110) en CMC formant un anneau de turbine (11) et une structure de support d'anneau (12). Chaque secteur d'anneau (110) présente en coupe radiale une forme de K, des pattes (113, 114) s'étendant à partir de la face externe de la base annulaire (111) au-dessus des portions d'extrémité (1110, 1111) de la base annulaire, les pattes (113, 114) et les portions d'extrémité (1110, 1111) de chaque secteur d'anneau (110) étant maintenues en vis-à-vis respectivement des pattes et des portions d'extrémité des secteurs d'anneaux adjacents (110) dans l'anneau (11). L'ensemble d'anneau de turbine comprend une pluralité de joints rigides (130) s'étendant chacun axialement entre deux secteurs d'anneau adjacents (110), et des dispositifs de maintien élastique (140) exerçant une force apte à maintenir les joints (130) en contact avec les portions d'extrémité (1110, 1111) ou les pattes (113, 114) de deux secteurs d'anneau adjacents (210).
