Abstract: A turbine vane assembly for use in a gas turbine engine includes turbine vanes, a segmented inner vane support, and an outer vane support. The turbine vanes are arranged around a central axis of the engine. The inner vane support is arranged radially inwardly of the turbine vanes. The outer vane support includes a full-hoop outer support ring located radially outward of the plurality of turbine vanes and extends entirely circumferentially about the central axis. The outer vane support further includes a plurality of discrete support spars coupled to the full-hoop outer support ring and extending radially inward from the full-hoop outer support ring through an interior cavity of a respective turbine vane.

Abstract: A method of manufacturing a planet carrier of a gearbox comprises manufacturing a plurality of preforms. Each preform comprises a base portion, a first end portion connected to a first end of the base portion, a second end portion connected to a second end of the base portion, a first side portion connected to a first side of the base portion, a second side portion connected to a second side of the base portion and a top portion. The first and second end portions and the first and second side portions are folded relative to the base portion and the top portion is folded and the adjacent edges of the portions of each preform are secured together to form a support structure. A first ring and a second ring are manufactured. The first and second end portions of each support structure are secured to the first and second rings respectively.

Abstract: A method and apparatus for applying a cladding layer to a surface of a component uses a cladding tool having a maximum reach less than the size of the surface. Geometry of the surface is segmented into a plurality of tessellated segments, each of which has a peripheral extent determined by a maximum reach of the cladding tool. A nominal tool subpath for each tessellated segment is generated, and then combined to generate a nominal tool path for depositing the cladding layer on the surface. The surface is clad using the nominal toolpath, including a process of adjusting the nominal tool path to an adjusted tool path that accounts for dimensions of the bead to be deposited by the tool to match an edge of the bead to be deposited with an edge of a previously deposited bead.

Abstract: A method of heat treating a localised region of a component including providing a heat treatment assembly with two or more subassemblies. Each subassembly is configured to partially circumscribe a portion of the component for heat treatment. Each subassembly includes a housing configured to partially circumscribe a portion of the component. An insulator and a heater are provided within the housing and extend to partially circumscribe a component and are arranged such that the insulator is between a wall of the housing and the heater. The method includes positioning the subassemblies adjacently around the component so that the subassemblies fully circumscribe the component. The subassemblies are connected together. The method includes activating the heater to heat the component in a region adjacent the heater.

Abstract: A method of forming a bonded assembly (10). The method comprises: providing at least first and second parts (12, 14) of an assembly (10) to be bonded; assembling the first and second parts (12, 14) in a required relative position to define a bond interface region therebetween; sealing part way along an edge (18) of the bond interface region using laser beam welding to define a cavity between the first and second parts (12, 14); in a vacuum environment, sealing the remainder of the edge (20) of the bond interface region using electron beam welding to form a fluid tight seal around the cavity; and applying heat and pressure to an external surface of the cavity to diffusion bond the first and second parts (12, 14) together.

Abstract: A method and apparatus for removing a canister 12 from a component 18 by forming an opening 30 in the canister wall thickness 14, 16 and introducing a pressurised fluid into the opening 14, 16 causing hydrostatic pressure build up between an internal canister surface 14 and the component 18, leading to the removal of the canister 12. This method and apparatus obviates the need to expend significant machining or chemical processing to remove the canister 12.

CPC classification number: F16B5/0088 , F16B7/0406
Abstract: A joint assembly joins first and second components about a common axis. The first component has a first end portion having a radially outwardly facing surface shaped to fit radially inside a second surface of a hollow second end portion of the second component to form an interface between the opposing first and second surfaces. The first and second surfaces have a concavity extending laterally with respect to the axis such that when the first and second surfaces are opposingly arranged the opposing concavities define a cavity at the interface. A retaining member is insertable into the cavity at the interface to prevent axial separation of the first and second components. One of the first and second end portions has a free end protrusion axially spaced from the concavity and the other of the first and second end portions has an axially extending recess arranged to receive the free end.
