Abstract

Ensemble d’anneau de turbine avec bride radiale améliorée L’invention concerne un ensemble (2) d’anneau de turbine doté d’un anneau de turbine (4) sectorisé en CMC et d’une structure de support d’anneau (6), chaque secteur (10) comprenant une base (12) à partir de laquelle s’étendent radialement vers l’extérieur une patte d’accrochage amont (16) et une patte d’accrochage aval (14) espacées axialement, la structure de support (6) comportant une bride radiale amont (62) et une bride radiale aval (64) entre lesquelles sont maintenues les pattes d’accrochage (14, 16). En regard de chaque jonction inter-secteur (100) entre deux secteurs d’anneau (10) adjacents dans la direction circonférentielle (DC), la bride radiale aval (64) comprend une portion d’ajustement (70) usinée dans l’épaisseur de la bride radiale aval (64), depuis une face amont (642) de la bride radiale aval (64), et s’étendant radialement depuis l’extrémité radiale intérieure (643) de la bride radiale aval (64), l’épaisseur de la bride radial aval (64) étant mesurée selon la direction axiale (DA), et la portion d’ajustement (70) de la bride radiale aval (64) étant axialement distante de la jonction inter-secteur (100) en regard de laquelle elle est disposée.
