A seal assembly to seal a gas turbine hot gas path flow in a gas turbine, the seal assembly comprising:a shim seal including, a first shim seal segment, a second shim seal segment, a third shim seal segment, and at least one additional shim seal segment, the shim seal disposed in a slot, on a low-pressure side of the slot, facing a low-pressure side of the gas turbine hot gas path flow, wherein the slot includes a plurality of slot segments,
wherein each of the first shim seal segment, the second shim seal segment, the third shim seal segment, and the at least one additional shim seal segment define a corner region,
wherein the first shim seal segment and the second shim seal segment are separated by a gap defined between their respective corner regions,
wherein the second shim seal segment and the third shim seal segment are separated by a gap defined between their respective corner regions, and
wherein the third shim seal segment and the at least one additional shim seal segment are separated by a gap defined between their respective corner regions,
a backup intersegment seal including a first backup seal segment, a second backup seal segment, a third backup seal segment, a fourth backup seal segment and at least one additional backup seal segment, wherein the backup intersegment seal is disposed in the slot on a high-pressure side of the slot, facing a high-pressure side of the gas turbine hot gas path flow, the backup intersegment seal disposed overlying the shim seal,
wherein the first backup seal segment and the second backup seal segment define a seal intersection there between, the seal intersection located at the corner region of the first shim seal segment,
wherein the second backup seal segment and the third backup seal segment define a seal intersection there between, the seal intersection located at the corner region of the second shim seal segment,
wherein the third backup seal segment and the fourth backup seal segment define a seal intersection there between, the seal intersection located at the corner region of the third shim seal segment, and
wherein the fourth backup seal segment and the at least one additional seal segment define a seal intersection there between, the seal intersection located at the corner region of the at least one additional shim seal segment, and
wherein the shim seal seals each of the corner regions; and

AERODYNAMIC LINK IN PART OF A TURBINE ENGINE

Safran Aircraft Engines, ...

1. Part of a turbine engine, said part having an axis and comprising:radially to said axis, an internal structural limit and an external structural limit which limit therebetween a stream of the turbine engine,
a first arm and a second arm, each passing through said stream of the turbine engine in which stream the first arm, which is structurally distinct from the second arm, is disposed upstream from the second arm, the first arm connecting together the internal structural limit and the external structural limit, and, separately from the first arm, the second arm connecting together the internal structural limit and the external structural limit, and
an aerodynamic linking device which comprises:
first and second fairings extending in the stream, between the first arm and the second arm,
first compressible interface means and second compressible interface means, the first compressible interface means being interposed between the first and second fairings and the first arm, and the second compressible interface means being interposed between the first and second fairings and the second arm, and
pressure retaining means for urging the first and second fairings towards each other which applies a pressure to the first and second arms, and which compress the first and second compressible interface means.

METHOD FOR FRICTION-WELDING A BLADE TO A TURBOMACHINE VANE, INCLUDING A SURFACING PROCESS

Safran Aircraft Engines, ...

1. A method for friction-welding a blade to a rotor disk of a turbomachine, with the rotor disk comprising a projecting block having an outer surface to which the blade is to be welded, the method comprising the following steps:a) carrying out a surfacing process on at least a part of a periphery of the projecting block, in the region of said outer surface;
b) machining the outer surface of the projecting block and of the surfacing, in order to put them at the same level so as to obtain an enlarged welding surface;
c) friction-welding is then carried out between the enlarged surface and the blade;
wherein the projecting block is positioned on the rotor disk in a predetermined direction, along a first height, after machining and prior to friction-welding, then along a second height, smaller than the first height, after friction-welding; and
wherein, in at least one of a direction perpendicular to the outer surface of the projecting block and a direction parallel to said predetermined direction, the surfacing process is performed along a height smaller than the difference between the first height and the second height.

CAST GAS TURBINE ENGINE COOLING COMPONENTS

Rolls-Royce Corporation, ...

1. A method comprising:filling a sacrificial composition in a plurality of cooling channels on a substrate, wherein a plurality of support structures integral with and extending from the substrate define the plurality of cooling channels, wherein respective support structures of the plurality of support structures define respective contact surfaces distal from the substrate, and wherein the sacrificial composition substantially fully fills the plurality of cooling channels and leaves the respective contact surfaces substantially uncovered; and
casting a cover layer onto the respective contact surfaces of the plurality of support structures, wherein the substrate comprises a first alloy composition, wherein the cover layer comprises a second alloy composition, and wherein casting the cover layer onto the respective contact surfaces comprises:
positioning the substrate, the integral support structures, and the sacrificial composition in a casting mold; and
introducing a molten casting composition into the casting mold to contact the molten casting composition to at least a portion of a casting core comprising the substrate.
