The calculation of take-off run
This is an aeronautical engineering report from 1934 on calculating aircraft take-off run, published by NASA through its Technical Reports Server, with no stated audience beyond aeronautical engineers. The pictures are plain line graphs with black curves on gridded paper, plotting ratios such as final to initial thrust against take-off coefficient, velocity ratios, time coefficient against thrust-to-drag, and a family of labelled curves for weight effect on take-off run. A designer might take from them the clean, sparse vocabulary of technical charts: thin gridlines, single dark curves and small serif labels.
