Abstract
Ensemble d’anneau de turbine à dispositif de refroidissement amélioré Ensemble d’anneau de turbine comportant un anneau de turbine en matériau composite à matrice céramique et un carter en alliage métallique (12) formant structure de support d'anneau, dans lequel le carter comporte une virole centrale (12a) de laquelle se déploient radialement des brides annulaires amont (26) et aval (28) entre lesquelles sont maintenues des pattes d'accrochage amont et aval (22, 24) s’étendant radialement d’une base annulaire (20) de chaque secteur d'anneau, la bride annulaire amont (26) étant pourvue de trous de ventilation destinés à alimenter un dispositif de refroidissement en air de refroidissement formé d’une pluralité de secteurs d’entretoise (14) en alliage métallique, chaque secteur d’entretoise s’étendant entre les pattes d’accrochage amont et aval pour en épouser la forme à une distance d de diffusion près, une partie radialement interne du secteur d’entretoise intégrant des trous de refroidissement (14a) formant diffuseur d’air pour refroidir par impact une surface externe (20b) de la base annulaire des secteurs d’anneau. Figure pour l’abrégé : Fig. 2.
