Patent number: 10066929Abstract: Method for measuring residual strain in a cured composite part includes taking a first image of at least two spaced apart particles positioned on a side of the cured composite part with the side positioned transverse to a first face side. The cure composite part includes a first ply has fibers and a second ply has fibers wherein the first ply and the second ply are positioned in overlying relationship to one another. At least a portion of the fibers of the first ply are positioned in angular relationship with at least a portion of the fibers of the second ply. The at least two spaced apart particles are associated with the second ply. Further included is a step of removing at least a portion of the first ply and taking a second image of the at least two spaced apart particles.Type: GrantFiled: April 25, 2017Date of Patent: September 4, 2018Assignee: THE BOEING COMPANYInventors: Haozhong Gu, Ying Shan, Chi Ho Eric Cheung, Aaron N. Rinn, Jeffrey Olberg, Kevin E. McCrary

Patent number: 9019683Abstract: A method for sealing an interface to attenuate high energy currents and voltages traveling thereacross may include forming a cover defining an inner volume shaped to enclose the interface; forming a filled sealant including a semi-rigid sealant mixed with a filler having a multiplicity of discrete particles of different composition than the semi-rigid sealant; placing the filled sealant within the inner volume; and placing the cover containing the filled sealant over the interface such that the filled sealant is adjacent the interface.Type: GrantFiled: April 24, 2014Date of Patent: April 28, 2015Assignee: The Boeing CompanyInventors: Arthur C. Day, James P. Irwin, Eddie Kwon, Carl R. McIver, Kevin E. McCrary

Patent number: 8020673Abstract: A braking system for a high speed, high load rotor operating in a vacuum and suspended by a magnetic field such as in a flywheel energy storage device includes a pair of calipers disposed on opposed sides of the rotor for actuating a pair of annular friction discs into engagement with opposed sides of the rotor. Each caliper includes a mounting ring on its outer edge and an inner shallow annular groove in which it disposed one of the friction discs. A circulating fluid under pressure is directed into each annular groove for urging each friction disc into engagement with one of the opposed surfaces of the rotor for safely bringing the rotor to a stop such as in an emergency. The circulating fluid removes the heat generated by the braking action, while the controlled pressure applied by the discs also controls the position of the rotor when static such as during initialization.Type: GrantFiled: July 30, 2007Date of Patent: September 20, 2011Assignee: The Boeing CompanyInventors: Carl R. McIver, Kevin E. McCrary, John R. Hull, John A Mittleider

Patent number: 7992278Abstract: A method of operating a production line comprises the steps of supporting equipment in the production line on a plurality of crawlers comprising at least one rolling track and a structural support for supporting the equipment. A first plurality of lifting magnets coupled to an interior surface of said at least one rolling track is configured to oppose a second plurality of lifting magnets coupled to an exterior surface of said structure support to lift the structural support, such that the structural support floats between and within said at least one rolling track. The magnetic fields experienced by the first and second plurality of lift magnets are adjusted to translate the at least one rolling track, such that the crawlers move along the production line.Type: GrantFiled: October 24, 2008Date of Patent: August 9, 2011Assignee: The Boeing CompanyInventors: Kevin E. McCrary, Arthur C. Day, John Edwards, Richard A. Hawkins, Mark D. Higgins, Philip E. Johnson, John A. Mittleider, James R. Schindler, Michael Strasik

Patent number: 7461711Abstract: An equipment-carrying crawler (20) includes a rolling track (44) and a structural support (70). The structural support (70) supports equipment (16). Lifting magnets (72) are coupled to the rolling track (44) and to the structural support (70). The lifting magnets (72) are configured to oppose each other, lift the structural support (70), and aid in the translation of the rolling track (44).Type: GrantFiled: November 24, 2004Date of Patent: December 9, 2008Assignee: The Boeing CompanyInventors: Kevin E.

Patent number: 6046139Abstract: We make large (in excess of 2 cm in diameter), single crystal YBa.sub.2 Cu.sub.3 O.sub.7-x [123 YBCO] crystals, where x.ltoreq.0.6, in a seventeen step process or some variant thereof from finely ground and well mixed 123 YBCO and 211 YBCO powders with a small amount of Pt by controlling the rate of cooling from within a compact of the powders using a temperature gradient in the radial and axial planes (independently) of about 1-1.degree. C./inch diameter of compact to nucleate the crystal growth. We promote crystal growth as well using a samarium oxide seed crystal, preferably SmBa.sub.2 Cu.sub.3 O.sub.(7-y), where y.ltoreq.1.6. After nucleation we cool the compact slowly at a rate from about 0.1-1.degree. C./hr to promote the single crystal development.Type: GrantFiled: August 7, 1998Date of Patent: April 4, 2000Assignee: The Boeing CompanyInventors: Kay Y. Blohowiak, Darryl F. Garrigus, Thomas S.
