Some of the more significant results of an experimental investigation of the influence of edge shape on the aerodynamic characteristics of a family of low aspect ratio wings (JR > 2), having straight trailing edges and taper ratios between zero and one, are presented.The results are shown to correlate with the approximate linear lifting-surface theory of Lawrence and with the semiempirical nonlinear theory of Flax and Lawrence. The discussion centers around (1) the effects of various leading and side-edge shapes, (2) the influence of leading edges, and (3) the effects of retreating side edges. Implications of the results as regards such design factors as lift-curve slope, stability and control, and leadingedge suction and drag are discussed. In addition, the possibility of developing a new type of roll control for low aspect ratio wings, based on edge-flow-separation effects, is considered.
