Abstract

L'invention concerne un ensemble (1) pour turbine, notamment pour une turbomachine, comportant un anneau de turbine (8) en matériau composite à matrice céramique, caractérisé en ce qu'il comporte au moins un support, ledit support étant fixé sur l'anneau de turbine (8), le support comportant un rebord (17) s'étendant circonférentiellement, destiné à être monté sur un carter (2), le support étant flexible de manière à autoriser un déplacement radial et/ou axial de l'anneau de turbine (8), par rapport au rebord (17) et au carter (2).The invention relates to an assembly (1) for a turbine, in particular for a turbomachine, comprising a turbine ring (8) made of a ceramic matrix composite material, characterized in that it comprises at least one support, said support being fixed to the 'turbine ring (8), the support comprising a flange (17) extending circumferentially, intended to be mounted on a housing (2), the support being flexible so as to allow a radial and / or axial displacement of the turbine ring (8), relative to the flange (17) and to the housing (2).
