A vane includes a forward rib and an aft rib positioned axially aft of the forward rib. The vane also includes a middle rib positioned axially between the forward rib and the aft rib, such that the forward rib and the middle rib define a forward passage configured to receive a forward baffle and the middle rib and the aft rib define an aft passage configured to receive an aft baffle. The vane also includes an inner surface extending axially from the forward rib to the aft rib, being radially separated from the middle rib via a gap such that air can flow between the aft passage and the forward passage via the gap, and having a radially outward curve from the forward rib to the middle rib and having a radially inward curve from the middle rib to the aft rib.

Applying material along parallel welding lines per welding layer, and by changing direction of extension of the welding tracks by 90° for the next welding layer, provided.

A turbine vane and a gas turbine including the same are provided. The turbine vane includes an airfoil having a pressure side and a suction side, at least one cooling channel formed radially in the airfoil, and an insert inserted into the at least one cooling channel to divide the cooling channel into a pressure side passage and a suction side passage.

A system and method for repairing a blade are provided. The system includes an induction heating coil configured for heating a platform and slash face of the blade. The induction heating coil extends under the platform and is adjacent to the slash face to provide substantially uniform localized heating to both the platform and slash face of the blade. The induction heating coil is configured so that the platform is visible during a repair or welding operation.

A stator for a gas turbine engine includes a stator vane, a first cooling passage located at the stator to provide a cooling fluid flow to a first portion of the stator, and a second cooling passage located at the stator to provide a cooling fluid flow to a second portion of the stator. A connection passage extends at least partially through the stator to connect a first cooling passage inlet of the first cooling passage to a second cooling passage inlet of the second cooling passage. The cooling fluid flow is directed from a common cooling flow source into the first cooling passage and the second cooling passage via the first cooling passage inlet.

A method for manufacturing a shaft body by welding a plurality of shaft members together and forming the shaft body, the method including: a primary tempering step of subjecting a range in at least one of the shaft members, which is in the vicinity of an end of another shaft member side adjacent thereto, to tempering before the shaft members are welded together so that a strength of an end side of a region thereof is lower than a strength at a side which is opposite to the end of the region thereof; a welding step of welding the shaft members together after the primary tempering step; and a secondary tempering step of tempering the vicinity of a weld part between the shaft members after the welding step.

A supporting structure for a gas turbine engine comprises an inner ring, an outer ring, and a plurality of circumferentially spaced, load carrying radial elements connecting the inner and outer rings, said radial elements being configured to transfer loads between the inner ring and the outer ring, wherein a gas channel for a primary axial gas flow is defined between the inner and outer rings, wherein the supporting structure has an inlet side for primary gas flow entrance and an outlet side for primary gas outflow, wherein the radial elements have an airfoil shape with a leading edge directed towards the inlet side, a trailing edge directed towards the outlet side, and two opposite sides connecting the leading edge and the trailing edge, and wherein at least a first of said radial elements is connected to an adjacent part of the supporting structure via a weld joint that extends across the leading edge and circumferentially at least partly around the first radial element.

An engine component for a gas turbine engine includes a main body and a plate. The engine component also includes a plurality of wire bristles disposed between the plate and the main body. A joint connects both the plate and the wire bristles to the main body and the joint is configured to prevent gas leakage between the main body, the plate, and the plurality of wire bristles.

Provided are a component and an additive manufacturing method for fabricating a component. The additive manufacturing method for fabricating a component includes providing a first wire segment and a second wire segment, the first and second wire segments each having a cross-sectional stackable geometry; positioning the first wire segment into an alignment with the second wire segment to form a workpiece stack, the alignment aligning adjacent surfaces in a line of sight direction; and directing an energy beam toward the first wire segment and the second wire segment along the alignment to weld the first wire segment to the second wire segment to form a welded stack. The component includes a workpiece stack comprising a plurality of wire segments welded together along aligned adjacent surfaces.
