  • Integrated gas purge path for welded sandwich structure
    Patent number: 10654125
    Abstract: A method of forming a weld on a work piece is disclosed. The method may include creating an internal cavity along the work piece and extending a conduit having an exit orifice into the internal cavity such that the exit orifice may be positioned adjacent to the weld to be formed. The method may further include supplying a purge gas to the conduit, the purge gas being carried through the conduit and pushed out of the exit orifice so as to displace undesirable gasses away from the weld to be formed and then subsequently forming the weld.
    Type: Grant
    Filed: February 18, 2016
    Date of Patent: May 19, 2020
    Assignee: The Boeing Company

  • Acoustically treated exhaust centerbody for jet engines and associated methods
    Patent number: 8025122
    Abstract: An acoustically treated exhaust centerbody comprising a body including a body fore portion and a body aft portion. An internal passageway extends through the body in the axial direction. A resonator in the body fore portion includes a plurality of acoustic chambers. A plurality of ribs in the resonator form fore/aft walls of the acoustic chambers. Each rib is shaped substantially as a section of an annulus. A plurality of radial fins extend between adjacent ribs. The fins form sidewalls of the acoustic chambers. A skin overlies the acoustic chambers and forms an outer surface of the resonator.
