  • Non-destructive inspection method with objective evaluation
    Patent number: 9903848
    Abstract: A method of non-destructive inspection evaluation includes converting a scan file of a part into a text file, determining whether the signal attenuation representative value is greater than a predetermined value and outputting a numeric score related to the signal attenuation representative value to signify a defect.
    Type: Grant
    Filed: December 30, 2008
    Date of Patent: February 27, 2018
    Assignee: Sikorsky Aircraft Corporation
    Inventors: John T. Wong, Dan Ursenbach
  • Composite aircraft floor system
    Patent number: 8709584
    Abstract: An aircraft floor system includes a composite panel which generally includes an inboard layer, an inboard interlock layer, a core layer, an outboard interlock layer and an outboard layer. The advanced sandwich core material may include K-Cor™ or X-Cor™ which is pinned through at least one ply of dry composite reinforcement to provide a mechanical lock between the pins and an inboard and outboard interlock layer. Bonding of the locked-in ply with the inboard and outboard results in improved structural performance and damage tolerance.
