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, la structure de support d’anneau (6) comprenant une entretoise (20) ayant une bride (20a) contre laquelle la patte aval (18) des secteurs d’anneau (10) est maintenue, un premier flasque amont (22) contre lequel la patte amont des secteurs d’anneau est maintenue, et en amont du premier flasque amont, un second flasque amont (24) de reprise d’efforts contre lequel le premier flasque amont est maintenu. Figure pour l’abrégé : Fig. 1.
