A vane assembly for a gas turbine engine comprising an axial loading element disposed between a mounting element of the vane ring and a cooperating portion of the supporting structure, such as to generate a load force therebetween in an axial direction. The axial load force limits unwanted relative movement between the vane ring and the supporting structure during operation of the gas turbine engine.

Axial loading element for turbine vane

A rotor assembly for a gas turbine engine, the rotor assembly comprises a plurality of cooling air deflectors made integral with the rotor disk to redirect air to a manifold at a bottom side of a corresponding blade retention slot on the periphery of the rotor disk.

Rotor assembly with cooling air deflectors and method

A simplified vane mounting arrangement by which a vane ring can be pre-assembled to an inner support ring before being installed in an outer casing.

Vane attachment arrangement

A rotor assembly for a gas turbine engine, the rotor assembly comprises a plurality of cooling air deflectors mounted on the rotor assembly to redirect air to a manifold at a bottom side of a corresponding blade retention slot on the periphery of the rotor disk.

The surface of a gas turbine blade is machined with a material-removing tool and simultaneously, an anti-oxidation coating is deposited on the surface using eletrospark deposition.
