Full-scale Wind-tunnel and Flight Test of a Fairchild 22 Airplane Equipped with a Zap Flap and Zap Ailerons
This is a 1937 NACA technical report, issued by the National Advisory Committee for Aeronautics, on full-scale wind-tunnel and flight tests of a Fairchild 22 airplane fitted with a Zap flap and Zap ailerons, written for aeronautical engineers. Its pictures are engineering graphs and plan drawings: velocity diagrams with curved flight-path grids, drag coefficient curves plotted against speed and Reynolds number, and dimensioned three-view and wing-section drawings. A designer might take from them the clean, precise style of technical line diagrams with labelled grid charts and annotated callouts.
