United States Patents Scalloped Wing Leading Edge United States Patent 6,431,498 Philip Watts; Frank E. Fish Abstract: An apparatus to modify a wing to provide increased lift over drag ratios compared to similar wings with straight leading edges. For wings extending in a lateral direction, and defining a longitudinal upstream direction, the apparatus forms a laterally extending leading edge facing in the upstream direction. The apparatus forms a plurality of protrusions spaced laterally along the leading edge, the protrusions creating a smoothly varying, alternately forward-and-aft sweep along the leading edge relative to the upstream flow direction along the leading edge. |
