Experiments with a device for shortening the glide and landing run of an airplane
This 1924 NACA technical report by the NASA Technical Reports Server collection describes experiments with a landing device meant to shorten an airplane's glide and landing run, written for aeronautical engineers and researchers. Its pictures are plain line drawings: wing airfoil profiles with small rectangular and triangular markings, a top-down wing plan with labelled dimensions, and a graph of velocity squared against distance with and without the device, offering a designer clean technical diagram conventions and labelled schematic layouts.
