Patent number: 9068251Abstract: A nickel-based superalloy is provided. Known nickel-based superalloys for producing components made of stem shaped single crystals do not provide sufficiently for grain boundary strength. The superalloy includes a low molybdenum content and very accurately adjusted values for elements having grain boundary strength and elements that precipitate in grain boundaries.Type: GrantFiled: October 20, 2009Date of Patent: June 30, 2015Assignees: SIEMENS AKTIENGESELLSCHAFT, HOWMET CORPORATIONInventors: Winfried Eβer, Dirk Goldschmidt, Christopher R.

Patent number: 8257032Abstract: A guide vane for a gas turbine with a vane base body which is of single-piece design and comprises a profiled vane blade extending between a vane root and a cover plate and also the vane root formed integrally with the vane blade and the cover plate formed integrally with the vane blade, is intended, in a relatively simple way to be able to be matched to the individual conditions of use with especially little outlay on apparatus and logistics. For this purpose, according to the invention, a flow-routing body with an advance guide blade that is connected upstream of the vane blade as seen in the direction of flow of the working medium of the gas turbine is joined to the vane base body.Type: GrantFiled: January 17, 2008Date of Patent: September 4, 2012Assignee: Siemens AktiengesellschaftInventors: Alexander R.

Patent number: 8128357Abstract: The invention relates to a guide blade segment of a thermal turbomachine, in particular a gas turbine, comprising a number of profiled blades which are arranged on a platform. A plurality of securing elements for securing the guide blade segment to an associated guide blade support are arranged on the side of the platform which is oriented away from the blade. The aim of the invention is to provide a guide blade segment which can be produced in a simple and economical manner avoiding casting problem areas enabling the guide blade segment to be attached in a particularly reliable and secure manner to the associated guide blade support. According to the invention, at least one section of at least one of the securing elements is a separately produced component which is rigidly connected to the platform or to an additional section of the securing element.Type: GrantFiled: February 21, 2007Date of Patent: March 6, 2012Assignee: Siemens AktiengesellschaftInventors: Katharina Bergander, Georg Bostanjoglo, Tobias Buchal, Winfried Eβer, Dirk Goldschmidt, Torsten Koch, Rudolf Küperkoch, Thorsten Mattheis, Jan Münzer, Ralf Müsgen, Matthias Oechsner, Ursula Pickert, Volker Vosberg

Patent number: 7967183Abstract: The invention relates to a method for repairing components comprising a base material with an oriented microstructure, wherein the repair point comprises a correspondingly oriented microstructure as the surrounding base material. According to the inventive method, solder is applied in the region of a point which is to be repaired and is soldered to the component by means of a heating effect produced by a device. A temperature gradient, i.e., approximately a temperature characteristic, is produced during the heating effect, said temperature characteristic ranging from a high to a low temperature in the region of the point which is to be repaired.Type: GrantFiled: January 28, 2005Date of Patent: June 28, 2011Assignees: Siemens Aktiengesellschaft, MTU Aero Engines GmbHInventors: Dirk Goldschmidt, Matthias Oechsner, Michael Ott, Uwe Paul, Ursula Pickert, Eckart Schumann, Beate Seiler, Robert Singer, Jan Steinbach, Andreas Volek, Volker Vosberg

Patent number: 7832988Abstract: A turbine blade with an aerodynamically profiled blade leaf which is produced from two assembled shell elements is provided. The shell elements forming the suction-side and the pressure-side blade leaf wall have been assembled by a high-temperature and high-pressure bonding process. In the region of the blade leaf tip, a cramp is provided which hooks the two blade walls together with one another with a form fit.Type: GrantFiled: May 29, 2007Date of Patent: November 16, 2010Assignee: Siemens AktiengesellschaftInventors: Katharina Bergander, Georg Bostanjoglo, Tobias Buchal, Winfried Eβer, Dirk Goldschmidt, Torsten Koch, Rudolf Küperkoch, Thorsten Mattheis, Jan Münzer, Ralf Müsgen, Matthias Oechsner, Ursula Pickert, Volker Vosberg

Publication number: 20100014980Abstract: There is described a turbine blade with an aerodynamically profiled blade leaf which is produced from two assembled shell elements. The shell elements forming the suction-side and the pressure-side blade leaf wall have been assembled by means of a high-temperature high-pressure bonding process and, under certain circumstances, may come apart at the blade tip. In order to prevent this, in the region of the blade leaf tip, a cramp is provided which hooks the two blade walls together with one another with a form fit.Type: ApplicationFiled: May 29, 2007Publication date: January 21, 2010Inventors: Katharina Bergander, Georg Bostanjoglo, Tobias Buchal, Winfried Esser, Dirk Goldschmidt, Torsten Koch, Rudolf Kuperkoch, Thorsten Mattheis, Jan Munzer, Ralf Musgen, Matthias Oechsner, Ursula Pickert, Volker Vosberg
