ABSTRACT:
An exhaust diffuser unit for a gas turbine engine includes an outer ring, a diffuser cone and vanes, all made from a ceramic matrix composite material. Each vane has end components which have apertures through which a metallic support strut extends. The support strut is rigidly secured at its radially outer end to a diffuser casing, and is slidably but non-rotatably received at its radially inner end in an aperture in a boss provided on a drum. Structural loads between the casing and the drum are transferred through the strut independently of the vane. Gas loads on the vane are transferred to the strut by way of metallic end components.
