Aerodynamic tests of a low aspect ratio tapered wing with various flaps, for use on tailless airplanes
A 1933 NACA technical report from the NASA Technical Reports Server, written for aeronautical engineers and researchers, presenting wind-tunnel aerodynamic tests of a low aspect ratio tapered wing fitted with various flap settings for tailless aircraft. The pictures are dense line graphs plotting lift and drag coefficients and centre of pressure against angle of attack in degrees, with multiple curves per chart distinguished by plotting symbols and flap angle keys, and a designer might take from them only the rough shapes of rising, peaking, and falling curves as abstract graphic motifs.
