Full-scale Wind-tunnel and Flight Tests of a Fairchild 22 Airplane Equipped with External-airfoil Flaps
This is a 1937 NACA technical report, published by the National Advisory Committee for Aeronautics for aeronautical engineers and researchers, on full-scale wind-tunnel and flight tests of a Fairchild 22 light airplane fitted with external-airfoil flaps. Its pages are dense engineering line graphs plotting lift, drag and moment coefficients against flap and angle settings, with one photograph of the aircraft on an airfield. A designer might take from them the clean grid-and-curve plotting style of mid-century technical publication, and the sleek silhouette of a 1930s high-wing monoplane.
