ABSTRACT:
A stator vane assembly for a gas turbine engine that includes a plurality of circumferentially spaced ceramic vanes, each of which has an inner and outer ceramic shroud, and a ceramic post extending from one of the shrouds, and a metallic platform having a plurality of circumferentially spaced sleeves. A tolerance ring is mounted in each of the sleeves and then the ceramic posts are pressed into the rings. The assembly is then ready to be mounted within the engine. A method for assembling these components to form the stator assembly is also described.
