A turbine rotor having an improved rotor tip, which has at least one cooling channel in the rotor blade, the cooling channel, in the region of its cuspidal point, having at least one locally limited constriction that is caused by a thickened portion at the end of a partition of the cooling channel.

Rotor-blade tip including cooling configuration

A method for repairing a damaged leading or trailing edge region of a metallic turbine blade, which has a suction-side blade wall, a pressure-side blade wall and a leading edge and a trailing edge, includes: removing the damaged leading or trailing edge region, with a cutout being formed; providing a replacement part which can be inserted in form-fitting fashion into the cutout and which restores the intended geometry of the turbine blade; inserting the replacement part in form-fitting fashion into the cutout in a predetermined insertion direction, and cohesively connecting the replacement part to the turbine blade, wherein mechanical connection of the replacement part and turbine blade using separate fastening elements is performed in addition to the cohesive connection.

Method for repairing a damaged leading or trailing edge region of a metallic turbine blade

A turbine blade tip, turbine blade and method where improved cooling is made possible by an improved cooling structure with cooling air holes inside a depression in a blade tip and a special arrangement of multiple cooling air holes which are supplied by a single cooling air channel inside a wall.

Turbine blade tip, turbine blade and method

A method for building structures on existing components includes preparing an auxiliary plate suitable for fastening on the working plate, wherein the auxiliary plate has at least one reference marking, fastening the component on the auxiliary plate, optionally processing the at least one surface to be processed for providing a surface that is substantially parallel to the working plane of the device, measuring the at least one reference marking and the component, wherein the position is recorded, introducing the auxiliary plate with the at least one reference marking and the component into the device and detachably fastening the auxiliary plate on the working plate and processing the component in the device for additive manufacturing by working data on the basis of measuring data. A device and a composite structure for additive manufacturing is used in the method.

Method for modifying components using additive manufacturing

A continuous flow machine has at least one annular guide vane carrier. The guide vane carrier, formed at least by a lower part and an upper part detachably connected to same, has at least three guide vane stages retained on the inner circumference of the at least one guide vane carrier, arranged axially behind one another in the flow direction and each having a plurality of radially extending guide vanes. Each of the guide vanes also has a guide vane blade, a base plate and a top plate, wherein the guide vane blade extends between the base plate and top plate. Via the arrangement of the securing pin in an intermediate space accessible in the assembled state, a partial disassembly of the individual guide vane stages is possible, independent of the remaining guide vane stages. The guide vane stages are conventionally mounted via retaining protrusions on neighbouring guide vane stages.

Continuous flow machine having multiple guide vane stages and method for partially disassembling a continuous flow machine of this type

An aid device for mounting and/or dismantling a guide ring segment which is to be attached or is held on a support, in particular a turbine guide blade guide support of a gas turbine is disclosed. The aid device having a main body, which can be fastened releasably fastened to the guide ring segment, and having a holding device, to which a traction mechanism can be fastened releasably, wherein the holding device is configured to transmit a pulling force to the main body, which pulling force acts via the traction mechanism in an installing direction or an expelling direction of the guide ring segment.
