Gottingen six-component scale measurements on a Junkers A 35 airplane model
A 1930 NASA technical memorandum reproducing wind-tunnel measurement charts from Gottingen tests of a scale model of the Junkers A 35 monoplane, prepared for aeronautical engineers and researchers. The pages are mostly line graphs of aerodynamic coefficients plotted on gridded paper, with one three-view style drawing of the aircraft showing wing area, span and weight. A designer could draw on the plain grid layouts, labelled axes and clean drafted line work as a restrained technical graphic vocabulary.
