  • Patent number: 10563769
    Abstract: The invention relates to a method for manufacturing a brush seal with inclined bristles. In order to be able to manufacture these brush seals in an especially cost-effective manner, at least the following steps are provided: provision of a brush blank with at least one metal thread or wire packing fastened at or in at least one wire core; local, at least partial heating of at least the wire core and/or a subregion of the thread or wire packing adjacent to the wire core, by a current flow through the wire core; bending of the thread or wire packing relative to the wire core for producing of the inclined position of the bristles of the brush seal. The invention further relates to an apparatus for manufacturing brush seals and a brush seal for a turbomachine, in particular for an aircraft engine.

  • Publication number: 20180326487
    Abstract: The invention relates to a layer-by-layer construction method for the additive manufacture of at least one region of a component. The layer-by-layer construction method comprises at least the following steps: a) application of at least one powder layer of a metallic and/or intermetallic material onto at least one buildup and joining zone of at least one lowerable building platform; b) layer-by-layer and local melting and/or sintering of the material for the formation of a component layer by selective exposure of the material with at least one high-energy beam in accordance with a predetermined exposure strategy; c) layer-by-layer lowering of the building platform by a predefined layer thickness; and d) repetition of steps a) to d) until the component region has been finished. The invention further relates to a layer-by-layer construction apparatus for the additive manufacture of at least one region of a component by an additive layer-by-layer construction method.

  • Patent number: 10070069
    Abstract: The invention relates to a method for the determination, at least in regions, of a contour of at least one additively manufactured component layer, in which a contour line of the component layer is traveled over, at least in regions, by a laser beam, and a time exposure of the traveled contour line is produced by a camera system. The invention further relates to a device for the determination, at least in regions, of a contour of at least one additively manufactured component layer. For this purpose, the device comprises at least one laser system, by which a contour line of the component layer can be traveled over, at least in regions, by a laser beam, and a camera system, which is designed to produce a time exposure of the contour line traveled over by the laser beam.

  • Publication number: 20150323318
    Abstract: A device for generative production of at least one component area of a component, in particular a component of a turbine or a compressor, is disclosed. The device includes at least one powder feed for application of at least one powder layer to a build-up and joining zone of a component platform that can be lowered and at least one radiation source for generating at least one high-energy beam by which the powder layer can be fused and/or sintered locally in the area of the build-up and joining zone to form a component layer. The device further includes a camera system which can produce at least one stereoscopic image for three-dimensional detection of at least one area of the component layer. A method for producing at least one component region of a component, in particular a component of a turbine or a compressor, is also disclosed.

  • Publication number: 20120024826
    Abstract: A method for welding two components is disclosed. In an embodiment, the method includes the following process steps. The two components are positioned such that the joining surfaces are opposite each other, at a short distance from each other. A high-frequency electrical current is conducted through the two components, heating the components at least in the region of the joining surfaces. The two components are pressed against each other such that the two joining surfaces are welded together.
