  • Aeroelastic tuned mass damper
    Patent number: 9388875
    Abstract: A method for damping aeroelastic modes, including limit cycle oscillations (LCO), is implemented by determining a mass for a tuned mass damper (TMD) based on an modal frequency for a mode having a potentially positive growth rate and attaching a TMD to at least one attachment point with significant motion such that a damping axis of the tuned mass damper is substantially oriented in a direction aligned with the local modal deflection.
    Type: Grant
    Filed: October 18, 2011
    Date of Patent: July 12, 2016
    Assignee: The Boeing Company
    Inventors: Jack S. Hagelin, Sascha K. Ruegamer, Tim D. Thornton, Sean C. O'Meara, Jeffrey R. Ellis, E. Fred Gylland, Jr.
