  • Method and apparatus for inducing controlled vortices to reduce afterbody drag
    Patent number: 6715717
    Abstract: A method and apparatus of creating vortices via vortex controllers, wherein the vortices are capable of entraining high-energy surrounding flow to induce a series of powerful longitudinal vortices that reattach separated flow by merging into single vortices along the undersurface of the afterbody to reenergize the fuselage boundary layer, thus preventing undersurface flow separation and reducing overall afterbody drag.
    Type: Grant
    Filed: September 6, 2002
    Date of Patent: April 6, 2004
    Inventors: Charles J. Dixon, Arthur C. Hughes

  • Method and apparatus for self-contained variable pitch and/or constant speed propeller including provisions for feathering and reverse pitch operation
    Patent number: 6672835
    Abstract: A self-contained variable pitch and/or constant speed propeller including provisions for feathering and reverse pitch operation, wherein no direct contact is required between the fixed engine or airframe and the rotating propeller for effectuation of blade pitch change, therefore eliminating the burdens and complexities general associated with propeller installation, maintenance and blade pitch change operations.
