Abstract
A flight control system provides a maximized mechanical advantage when the load of the airstream on the airfoil is also at a maximum. A control surface is pivotally mounted for movement through a range of positions between a neutral position at which airstream load thereon is a minimum and upwardly and downwardly deflected positions, the airstream load being a maximum in either of the deflected positions. An operator mechanism for moving the control surface between the upwardly and downwardly deflected positions includes a rotor mounted on the airfoil for rotation about a chordwise extending rotary axis and has a horn member with a terminal end offset from the rotary axis. The terminal end of the horn member is slidably engaged with the guide track and an actuator rotates the rotor and by reason of the slidable engagement of the horn member with the guide track moves the control surface.
