  • Hybrid ice protection system for use on roughness-sensitive airfoils
    Patent number: 6196500
    Abstract: An electro-thermal or hot gas anti-icer of the “running-wet” type is mounted at the leading edge of an airfoil. Mechanical de-icers are mounted on the surfaces aft of the anti-icer. The mechanical de-icers throw off ice without creating runback water, thereby eliminating runback refreeze ridges caused by a known hybrid ice-protection system. Advantageously, the de-icers are of a type in which the airfoil has a semi-rigid skin that forms an aerodynamic surface of the airfoil, and in which there is at least one mechanical actuator for flexing the skin.
    Type: Grant
    Filed: June 11, 1999
    Date of Patent: March 6, 2001
    Assignee: Cox & Company, Inc.
    Inventors: Kamel M. Al-Khalil, Thomas F. W. Ferguson
