Summary: | The invention relates to a turbine ring assembly which comprises a plurality of ring sectors (10) made of a composite material with a ceramic matrix forming a turbine ring (1) and a ring-supporting structure (3) including two flanges (32, 36). The ring sectors comprise two tabs (14, 16) which extend between the two annular flanges of the ring-supporting structure and each includes an annular groove (140, 160) into which an annular projection (34, 38) on each of the flanges of the ring-supporting structure is inserted. A resilient element (60; 70) is intercalated between the upper wall of the projection and the upper wall of the corresponding groove or between the lower wall of the projection and the lower wall of the corresponding groove.
Un ensemble d'anneau de turbine comprend une pluralité de secteurs d'anneau (10) en matériau composite à matrice céramique formant un anneau de turbine (1) et une structure de support d'anneau (3) comprenant deux brides annulaires (32, 36). Les secteurs d'anneau comprennent deux pattes (14, 16) s'étendant entre les deux brides de la structure de support d'anneau et possédant chacune une rainure annulaire (140, 160), dans laquelle s'insère une saillie annulaire (34, 38) portée par chacune des brides de la structure de support d'anneau. Un élément élastique (60; 70) est interposé entre la paroi supérieure de la saillie et la paroi supérieure de la rainure correspondante, ou entre la paroi inférieure de la saillie et la paroi inférieure de la rainure correspondante. |
