Thrust and power required in climbing
A technical report from the NASA Technical Reports Server, dated 1923, compiled as an aeronautical engineering study on thrust and power in climbing flight, written for engineers and aircraft designers. Its pictures are plain line graphs and schematic diagrams with solid and dashed curves plotted against velocity axes, labelled with symbols such as V0, Vw and Vmin, and a designer could borrow their clean curve-and-axis layouts for simple data-visualisation or infographic work.
