Results of experimental flights at high altitudes with Daimler, Benz and Maybach engines to determine mixture formation and heat utilization of fuel
This is a 1923 NASA technical report, compiled from a German aviation engine study, presenting results of experimental high-altitude flights with Daimler, Benz and Maybach engines. Its single picture is a set of graphs plotting engine performance against altitude in thousands of feet and distance in kilometres, with hatched shaded areas. A designer might take from it a clean, technical chart style with hatched fills, stepped curves and labelled axes for information graphics.
