CA 2752424
A CMC turbine stator blade 1 includes a blade 2 which is formed of a ceramic matrix composite material, and a band 11 which is formed of a ceramic matrix composite material or a metallic material and supports the blade 2. The blade 2 includes a first fitting portion 5 to which the band 11 is fitted at the outside thereof. The band 11 includes a second fitting portion 12 to which the first fitting portion 5 is fitted at the inside thereof. The CMC turbine stator blade 1 includes fixing means 6 which sandwiches the second fitting portion 12 from both sides in the height direction of the blade so that the blade 1 and the band 11 are fixed.
L'invention concerne un ensemble aube de stator de turbine CMC (1) pourvu de plusieurs aubes (2) en matériau composite à matrice céramique, et de bandes (11) fabriquées dans le même matériau composite à matrice céramique ou dans un matériau métallique, et qui servent de support aux aubes (2). Chaque aube (2) comprend une première partie de fixation (5) à l'extérieur de laquelle la bande (11) est fixée. La bande (11) comprend une seconde partie de fixation (12) à l'intérieur de laquelle est fixée la première partie de fixation. L'ensemble aube de stator de turbine CMC (1) comprend un système de fixation (6) qui prend en sandwich la seconde partie de fixation (12) dans le sens de la longueur de l'aube de manière à fixer l'aube (1) et la bande (11).
