Patent number: 7842231Abstract: An article made of constituent elements is prepared by furnishing at least one nonmetallic precursor compound, wherein all of the nonmetallic precursor compounds collectively contain the constituent elements. The constituent elements include a titanium-base metallic composition, boron present at a level greater than its room-temperature solid solubility limit, and, optionally, a stable-oxide-forming additive element present at a level greater than its room-temperature solid solubility limit. The precursor compounds are chemically reduced to produce a material comprising a titanium-base metallic composition having titanium boride particles therein, without melting the titanium-base metallic composition. The titanium-base metallic composition having the titanium boride particles therein is consolidated without melting.Type: GrantFiled: April 18, 2008Date of Patent: November 30, 2010Assignee: General Electric CompanyInventors: Andrew Philip Woodfield, Eric Allen Ott, Clifford Earl Shamblen, Michael Francis Gigliotti, David Alan Utah, Alan Glen Turner

Publication number: 20100180572Abstract: A FLADE fan assembly includes radially inner and outer airfoils extending radially inwardly and outwardly respectively from an annular shroud circumferentially disposed about a centerline. Inner and outer chords extend between inner and outer leading and trailing edges of inner and outer airfoil cross-sections of the radially inner and outer airfoils respectively. Inner and outer stagger angles between the inner and outer chords respectively at the shroud and the centerline are different. The radially outer airfoils may outnumber the radially inner airfoils and particularly by a ratio in a range of 1.5:1 to about 4:1. Load paths or radii may extend radially through the inner and outer airfoils and through the rotating shroud between the inner and outer airfoils and may pass near or through the inner and outer leading edges and through the inner and outer trailing edges.Type: ApplicationFiled: July 31, 2006Publication date: July 22, 2010Inventors: Aspi Rustom Wadia, Alan Glen Turner, Aaron Michael Dziech, Peter Nicholas Szucs, John Jared Decker

Patent number: 7758311Abstract: Including a disk, a plurality of circumferentially spaced apart airfoils extending radially outwardly from the disk, a plurality of shroud segments being disposed circumferentially between the plurality of airfoils and configured to attach to a corresponding airfoil of the plurality of airfoils and a plurality of wear surfaces, where at least one wear surface of the plurality of wear surfaces is configured and disposed to prevent excessive wear between the adjacent shroud segments. Each shroud segment of the plurality of shroud segments may be attached to a corresponding airfoil by weld connections to permit clearance during translation friction welding of the airfoil to the disk hub are located to avoid high stress areas.Type: GrantFiled: October 12, 2006Date of Patent: July 20, 2010Assignee: General Electric CompanyInventors: Kenneth Loehle, James A. Huffman, Charles K. Christopherson, Alan Glen Turner, Jeffrey F. Wessels, Gary Edward Trewiler, Peter J. Rock, Paul S. Manicke, Joseph Capozzi, Jeffrey Howard Nussbaum, Leslie M Pommer
