The Pressure Distribution over the Horizontal Tail Surfaces of an Airplane III
This is a 1923 NACA-style technical report, produced by the National Advisory Committee for Aeronautics for aeronautical engineers, on pressure distribution across an airplane's horizontal tail surfaces during flight. The pictures are plain black-and-white line graphs with dense curves, dashed and solid, plotted against time in seconds, plus a row of small diagrams showing wedge-shaped tail outlines with pressure contour lines at several seconds. A designer could borrow the sparse scientific chart grammar: labelled axes with dual scales, overlapping traces, and the schematic tail outline as a simple graphic motif.
