초록

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. ...

The invention claimed is: 1. A vane assembly for a gas turbine engine, the assembly comprising inner and outer support structures which respectively carry inner and outer rings defining an annular gas flow path between them, the assembly further comprising a plurality of hollow vanes which extend across the gas flow path and through respective openings in the inner and outer rings, a plurality of support struts extending between the support structures and through the vanes to locate the support structures relatively to each other, the vanes being provid...
