Patent number: 10076879Abstract: A method for the generative production of a component and a device for carrying out such a method, includes the following steps: applying a material layer with a constant layer thickness; solidifying a region of the material layer according to a component cross section; generating an eddy-current scan of the solidified region, a scan depth corresponding to a multiple of the layer thickness; determining a material characterization of the solidified region taking into consideration a previous eddy-current scan of solidified regions of lower-lying material layers; and repeating the steps until the component is assembled. An electric material characterization of each individual layer is determined using a recursive algorithm of individual measurements (monolayer by monolayer), and thus the entire component is tested step by step completely in a highly resolved manner.Type: GrantFiled: July 31, 2012Date of Patent: September 18, 2018Assignee: MTU AERO ENGINES AGInventors: Joachim Bamberg, Wilhelm Satzger, Thomas Hess

Patent number: 9964496Abstract: The invention relates to a method for the quality assessment of a component produced by means of an additive manufacturing method. In the course of the method, it is checked first of all whether the component violates predetermined absolute limits in order to rule out the existence of serious malfunctions in the additive manufacturing process. Subsequently, a component-dependent targeting process is determined. On the basis of this targeting process, the limits for deviations are established and deviating actual values of the component are isolated and assessed by means of various parameters.Type: GrantFiled: August 17, 2015Date of Patent: May 8, 2018Assignee: MTU Aero Engines AGInventors: Thomas Hess, Alexander Ladewig

Patent number: 9940282Abstract: A serial bus is provided with a device (sometimes herein referred to as an I2C serializer device) including circuitry and machine logic that operates as follows: when one of the master devices is using the bus for data communication, then the other master(s) will receive a wait signal until the bus becomes available again. This wait signal allows the master devices to wait as a “hardware response,” rather than requiring the master devices to be equipped with software and/or firmware to control the operation of waiting until the serial bus is available. In some embodiments, the use of the I2C serializer device allows a bus operating under a bus serialization protocol (for example, I2C) to be simultaneously connected to multiple master devices even in the case that one, or more, master device(s) do not include any currently conventional form of multi-master support.Type: GrantFiled: March 2, 2017Date of Patent: April 10, 2018Assignee: Inernational Business Machines CorporationInventors: Harald Freudenberger, Thomas Hess, Martin Raitza, Philip S.

Patent number: 9920838Abstract: A brush seal for a gas turbine, in particular an aircraft engine, is disclosed. The brush seal includes a support ring which has a support plate and a support structure, where the support structure is arranged downstream with respect to the support plate. The brush seal also includes bristles which are arranged upstream with respect to the support ring, where ends of the bristles protrude radially inward beyond the support plate. The support structure yields when a scraping force acting radially outward occurs on a first lateral surface of the support structure, where the first lateral surface is directed radially inward, and the support structure does not yield when an axial operating force occurs on a second lateral surface of the support structure.Type: GrantFiled: July 2, 2015Date of Patent: March 20, 2018Assignee: MTU Aero Engines AGInventors: Stephan Klaen, Julian Weber, Frank Stiehler, Christoph Cernay, Thomas Hess
