Abstract
A support and actuating system for large Fowler-type flaps on the trailing edge of an aircraft wing. Each flap is vertically and laterally supported at diagonally opposite corners, and the remaining leading-edge corner is vertically supported and laterally free to permit smooth and simple actuation. The flap is constructed to be torsionally stiff to eliminate need for conventional multiple flap tracks and support at the remaining trailing-edge corner. Elimination of some or all external tracks on the wing tracks provides a clean low-drag wing when the flaps are retracted in cruising flight, while enabling simple deployment of unusually large flaps for increased lift during landing, takeoff, and other low speed conditions. The flap system is useful on straight or rearwardly swept wings, and is particularly adapted to forwardly swept wings.
