  • Rotor hub fairing system for a counter-rotating, coaxial rotor system
    Patent number: 7530787
    Abstract: A rotor hub fairing system includes an upper hub fairing, a lower hub fairing and a shaft fairing therebetween. The rotor hub fairing system reduces the total drag on a dual, counter-rotating, coaxial rotor system. Other aerodynamic structures may be mounted to the shaft fairing, hub fairings and airframe to facilitate flow around the upper and lower hub fairings to reduce flow separation and drag.
    Type: Grant
    Filed: May 18, 2006
    Date of Patent: May 12, 2009
    Assignee: Sikorsky Aircraft Corporation
    Inventors: Fabio P. Bertolotti, Mark W. Scott, Brian E. Wake, T. Alan Egolf, Duane C. McCormick, Ebru Usta, Stuart S. Ochs
