Abstract: A contra-bevel driven control mechanism repositions a control surface in a fluid environment such as an aerodynamic or hydrodynamic environment. This involves mechanically coupling an airfoil and a control surface. The control surface may pivot about a spanwise axis between upwardly deflected and downwardly deflected positions. A forward beveled rotor mounted to the airfoil and an aft beveled rotor mounted to the control surface counter rotate. The forward beveled rotor rotates about a forward chordwise axis within the airfoil while the aft beveled rotor rotates about an aft chordwise axis within the control surface. The angular rotation between the forward beveled rotor and the aft beveled rotor deflects the aft beveled rotor and the aft chordwise axis within the control surface. Additionally, this method allows the control surface to be deflected with maximum mechanical advantage when the control surface is fully deflected.
