Patent number: 7810237Abstract: A method is for repairing and/or modifying component parts of a gas turbine. First, at least one, particularly damaged section of the component part that is to be repaired is cut out of the component part. In addition, if it does not exist, a data record is generated for a replacement part that is to be produced. The replacement part is subsequently produced with the aid of a rapid manufacturing process. Subsequently, the replacement part produced is integrated into the component part that is to be repaired.Type: GrantFiled: April 1, 2004Date of Patent: October 12, 2010Assignee: MTU Aero Engines GmbHInventors: Anja Lange, Jens Lange, Uwe Schulze

Patent number: 7774925Abstract: A method is provided for filling a hollow structure with metal foam. A mixture is made of a metal powder and a foaming agent. An electric resistance heating wire is provided and the mixture is consolidated into a solid preformed charge with the wire embedded in the charge and extending from the ends thereof. The preformed charge is placed into the hollow structure and electric current is applied to the resistance heating wire so that the metal powder is melted and the foaming agent foams the melted metal to fill the hollow structure.Type: GrantFiled: October 19, 2006Date of Patent: August 17, 2010Assignee: GM Global Technology Operations, Inc.Inventors: Asim Tewari, Anil K. Sachdev, Srinivas Subbarao
