Patent number: 9920642Abstract: Aspects of the present invention relate to systems and methods of a vane design utilizing welding techniques. The present invention concerns a method for preventing cracking within a vane assembly utilizing full penetration welding. Additional embodiments concern a vane design that, when assembled with another vane, comprises an axial slot that prevents cracking within a vane assembly.Type: GrantFiled: March 3, 2014Date of Patent: March 20, 2018Assignee: ANSALDO ENERGIA IP UK LIMITEDInventors: Richard Orsatti, Edward Len Miller

Patent number: 9890790Abstract: A compressor component having an airfoil with a profile in accordance with Table 1 is disclosed. The compressor component, such as a compressor blade, has an increased surface area over a portion of the airfoil chord length. The increased surface area allows for a greater amount of air to be taken in by the airfoil, thus increasing the air flow through the gas turbine engine.Type: GrantFiled: November 22, 2013Date of Patent: February 13, 2018Assignee: ANSALDO ENERGIA SWITZERLAND AGInventors: Edward Len Miller, Stephen Wayne Fiebiger, Wes Carl Smith, Wilm Philipp Hecker, Andreas Martin Mattheiss, Reiner Jochen Digele

Patent number: 9523284Abstract: A compressor component having an airfoil with a profile in accordance with Table 1 is disclosed. The compressor component, such as a compressor vane, has a decreased surface area over a portion of the airfoil chord length. The decreased surface area compressor vane operates in conjunction with a compressor blade having an increased surface area.Type: GrantFiled: November 22, 2013Date of Patent: December 20, 2016Assignee: GENERAL ELECTRIC TECHNOLOGY GMBHInventors: Edward Len Miller, Stephen Wayne Fiebiger, Wes Carl Smith, Reiner Jochen Digele, Wilm Philipp Hecker, Andreas Martin Mattheiss

Patent number: 9297259Abstract: A compressor component having an improved airfoil profile so as to eliminate previously known vibratory issues in the blade tip is disclosed. By altering the airfoil profile throughout its span, the natural frequency of the airfoil is altered so as to not coincide with a critical engine order of the compressor. Further, the present invention provides a novel airfoil profile in accordance with the coordinates of Table 1.Type: GrantFiled: June 14, 2012Date of Patent: March 29, 2016Assignee: Alstom TechnologyInventors: Edward Len Miller, Marco Micheli, Tihomir Stojkovic, Luis Federico Puerta

Patent number: 8596986Abstract: A compressor component having an airfoil with a profile in accordance with Table 1 is disclosed. The compressor component, such as a compressor blade, has an increased thickness over a portion of the airfoil span in order to increase stiffness. Furthermore, the airfoil has been restacked so as to induce a compressive stress in the blade root/attachment area. The increased stiffness and restacked airfoil combine to improve high-cycle fatigue capability of the compressor component.Type: GrantFiled: February 23, 2011Date of Patent: December 3, 2013Assignee: Alstom Technology Ltd.Inventors: Edward Len Miller, William David Day, Hitesh Narendra Patel, Jeffrey S. Taylor

Publication number: 20130011265Abstract: Gas turbine vanes of a gas turbine vane assembly have a reconfigured platform shape so as to reduce the ingestion of hot combustion gases into platform gaps between adjacent vane assemblies is disclosed. The vane platforms are configured so the joint between adjacent vanes is repositioned a sufficient distance away from the leading edge of the vane airfoil and the associated bow wave generated by the hot combustion gases passing over the airfoil leading edge.Type: ApplicationFiled: July 5, 2011Publication date: January 10, 2013Applicant: ALSTOM TECHNOLOGY LTD.Inventors: EDWARD LEN MILLER, YONG WANG, STEPHEN WAYNE FIEBGIER
