摘要： A coupon for repairing a part is disclosed. The coupon includes an outwardly threaded body configured to mate with an inwardly threaded opening in a damaged area of the part. The part and/or coupon may include a superalloy. The threaded arrangement converts tensile stresses into shear stresses that allow the repair to exhibit material characteristics as good as or better than the superalloy. A method of using the coupon to repair a part using brazing, and a turbomachine part using the coupon, are also disclosed.

摘要： A method for reconditioning a hot gas path part of a gas turbine to flexibly adapt an operation regime of said gas turbine for subsequent operation intervals. The method includes providing a hot gas path part to be reconditioned; removing a predetermined area of the hot gas path part, resulting in a cutout at the hot gas path part; and manufacturing a coupon for insertion into the cutout to replace the removed area of the hot gas path part. The method further includes inserting the coupon into the cutout; and joining the hot gas path part with the coupon. The coupon is manufactured by a selective laser melting method resulting in a fine grain sized material with significantly improved low cycle fatigue lifetime. The hot gas path part is coated, at least in an area including the inserted coupon, with a metallic overlay with improved thermo-mechanical fatigue and oxidation lifetime.

摘要： A gas turbine includes an exhaust cylinder comprising an inner circumferential slot, a diffuser shell disposed at least substantially concentrically within the exhaust cylinder and one or more baffle plates extending between the exhaust cylinder and the diffuser shell, a proximal end of each of the one or more baffle plates being fixed to the diffuser shell by one or more holding rings and a distal end of each of the one or more baffle plates being slidingly received within the inner circumferential slot of the exhaust cylinder. The one or more holding rings are secured to the diffuser shell, at one or more holding segments disposed along an inner diameter of the diffuser shell, via a plurality of radially inserted fastening members.

摘要： A rigid electrical raft has electrical conductors embedded in a rigid material. The electrical conductors transmit electrical signals through the rigid electrical raft, which may form part of an electrical system of a gas turbine engine. The rigid electrical raft also has electrical heating elements embedded therein. The electrical heating elements provide heat which may be used, for example, to prevent condensation and/or ice build-up and/or to raise the temperature of electrical components to be within a desired range.

摘要： A superalloy component such as a gas turbine engine blade (40) having a ceramic thermal barrier coating (41) is repaired using a textured repair foil (30). A degraded region of the thermal barrier coating is removed (14) and the underlying superalloy material surface is prepared (16) for re-coating. The repair foil is includes a layer of boron-free braze material (34) and a layer of superalloy material (32) having a textured surface (36). The foil is brazed (18) to the prepared surface during a solution heat treatment effective to homogenize the braze (20). A new area of thermal barrier coating (46) is applied over the foil with a bond that is enhanced by the texturing of the foil surface.
