Abstract

Ensemble d’anneau de turbine monté sur entretoise L’invention concerne un ensemble (2) d’anneau de turbine s’étendant autour d’une axe (X-X), comprenant une pluralité de secteurs d’anneau (10) en matériau composite à matrice céramique formant un anneau de turbine (4) et une structure de support d’anneau (6) maintenue par un carter de turbine (32), chaque secteur d’anneau (10) comprenant une base (12) à partir de laquelle s’étendent radialement vers l’extérieur une patte amont (16) et une patte aval (18) espacées axialement l’une de l’autre. L’ensemble (2) comprend en outre au moins deux pions transversaux (40) par secteur d’anneau (10), chaque pion transversal (40) traversant axialement l’entretoise (20), un secteur d’anneau (10), et le carter de turbine (32) pour maintenir l’anneau de turbine (4), le support d’anneau (6) et le carter de turbine (32) solidaires les uns des autres. Figure pour l’abrégé : Fig. 1.
