  • Manufacture of thermoplastic core
    Patent number: 9840043
    Abstract: One aspect of a method of manufacturing a honeycomb core includes positioning a first thermoplastic columnar cell adjacent a second thermoplastic columnar cell, modifying a thermoplastic property of the first thermoplastic columnar cell, wherein the modified thermoplastic property permits joining a circumferential surface of the first thermoplastic columnar cell to a circumferential surface of the second thermoplastic columnar cell. The method also includes joining the circumferential surface of the first thermoplastic columnar cell having the modified thermoplastic property to the circumferential surface of the second thermoplastic columnar cell resulting in the honeycomb core.
    Type: Grant
    Filed: February 17, 2015
    Date of Patent: December 12, 2017
    Assignee: BELL HELICOPTER TEXTRON INC.
    Inventors: Elliott Keller Schulte, Robert Brack, Kathleen Oldham

  • Method of machining a thin-walled structure
    Patent number: 9364930
    Abstract: A method of manipulating a thin-walled structure includes providing a thin-walled structure in a first unconstrained configuration, constraining the thin-walled structure to a first constrained configuration in which a first feature of the thin-walled structure is spatially located relative to the a second feature of the thin-walled structure in a predetermined manner, wherein an open volume of the thin-walled structure is constrained to maintain a predetermined open volume shape, and machining the thin-walled structure to a second constrained configuration in which the first feature of the thin-walled structure remains spatially located relative to the second feature of the thin-walled structure in the predetermined manner.
