Modern Manufacturing Equipment of the Ernst Heinkel Airplane Works
This is a 1938 NASA technical report, a memorandum on machinery and manufacturing equipment at the Ernst Heinkel aircraft works, written for aeronautical engineers and aircraft production staff. The pictures are plain black-and-white engineering diagrams and photographs: a tube-wall graph, riveted joint sections, a contracting-pressure curve chart, and photographs of duralumin tubes, push rods and a cutter. A designer could take from them the stark, measured look of mid-century technical documentation, with its dense line work, labelled graphs and grey metal textures.
