Patent number: 11060412Abstract: A method for controlling a gap minimization for an adjustable gap between a rotor and a housing of a gas turbine carried out on the basis of a correlation extracted from simulation data. If the actual value (PI) lies below the lower threshold (PU), the gap minimization is deactivated, whereas if the actual value lies above the upper threshold (PO), the gap minimization is activated. The gap minimization is activated between the thresholds (PU, PO) if the actual value lies above the threshold (PG) but is deactivated if the actual value (PI) lies below the threshold (PG).Type: GrantFiled: March 11, 2019Date of Patent: July 13, 2021Assignee: Siemens Energy Global GmbH & Co. KGInventors: Hans-Georg Gamm, Marcus Hüning, Uwe Kahlstorf

Patent number: 10294818Abstract: A gas turbine having at least one inner and outer housing part, between which two housing parts a ring channel is at least partially arranged, which ring channel circumferentially surrounds the useful flow of the working fluid prevailing during operation of the gas turbine and circumferentially surrounds the gas turbine rotor. The ring channel is designed to conduct a cooling fluid in the circumferential direction, wherein the ring channel is divided into ring sectors in the circumferential direction by separators. A tube is at least partially provided in the ring channel which fluidically connects individual ring sectors to each other, and is designed as a distributing tube, which is fluidically connected to at least one cooling-fluid line for conducting cooling fluid and has at least one outlet opening, which at least one outlet opening is designed to transfer the cooling fluid from the tube into the ring sectors.Type: GrantFiled: August 12, 2015Date of Patent: May 21, 2019Assignee: Siemens AktiengesellschaftInventors: Marcus Hüning, Otmar Gossmann, Uwe Kahlstorf

Patent number: 9074490Abstract: A gas turbine including a plurality of hook elements disposed one inside the other and designed substantially in the form of hollow cones or hollow cylinders, and including a stator blade support, is intended to enable an especially high efficiency while maintaining the greatest possible operating safety and operating life. To this end, at least one of the hook elements or the stator blade support has a substantially elliptical cross-sectional contour.Type: GrantFiled: September 15, 2009Date of Patent: July 7, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Francois Benkler, Tobias Buchal, Andreas Böttcher, Martin Hartmann, Patricia Hülsmeier, Uwe Kahlstorf, Ekkehard Maldfeld, Dieter Minninger, Michael Neubauer, Peter Schröder, Rostislav Teteruk, Vyacheslav Veitsman

Patent number: 9057281Abstract: An axial turbomachine including a rotor-blade cascade is provided. The turbomachine includes a casing in which the cascade is installed and a guide-blade carrier which encloses the cascade and is integrated into the inner side of the housing. The guide-blade carrier is arranged immediately adjacently to the blade tips faulting a radial gap, wherein the guide-blade carrier is mounted in the housing, such that it may be displaced parallel to the axis of the axial turbomachine, and includes an adjusting ring which is supported on contact surfaces on the housing and guide-blade carrier and may be rotated about the axis, wherein the contact surfaces of the adjusting ring and of the housing and/or of the guide-blade carrier are set with respect to a plane perpendicular to the axis, so that, when the adjusting ring is rotated about the axis, the guide-blade carrier is displaced axially by the adjusting ring.Type: GrantFiled: March 22, 2010Date of Patent: June 16, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Francois Benkler, Andreas Böttcher, Uwe Kahlstorf, Torsten Matthias, Dieter Minninger, Oliver Schneider, Peter Schröder, Vyacheslav Veitsman

Patent number: 8870526Abstract: A stator blade carrier for a gas turbine is provided. The stator blade carrier includes a plurality of axial segments. At least one axial segment is designed as a tubular lattice structure. This allows a simpler design technically and a more flexible adaptation to the temperature profile present on the stator blade carrier to maintain operational safety.Type: GrantFiled: September 10, 2009Date of Patent: October 28, 2014Assignee: Siemens AktiengesellschaftInventors: Roderich Bryk, Sascha Dungs, Martin Hartmann, Uwe Kahlstorf, Karl Klein, Oliver Lüsebrink, Mirko Milazar, Nicolas Savilius, Oliver Schneider, Shilun Sheng, Vadim Shevchenko, Gerhard Simon, Norbert Thamm

Patent number: 8545171Abstract: A rotor of a thermal fluid flow machine, especially a gas turbine, is provided. The rotor includes a plurality of rotor components that are held together by a common tie-bolt that extends through the center of the rotor components. The tie-bolt is fixed in at least one of the rotor components using at least one star spring that surrounds the tie-bolt in a circumferential direction.Type: GrantFiled: February 15, 2008Date of Patent: October 1, 2013Assignee: Siemens AktiengesellschaftInventors: Francois Benkler, Ulrich Ehehalt, Harald Hoell, Uwe Kahlstorf, Karsten Kolk, Walter Loch, Peter-Andreas Schneider
