The Physical Effects of Detonation in a Closed Cylindrical Chamber
A 1935 report from the National Advisory Committee for Aeronautics, published in the United States for engine researchers and aeronautical engineers, documenting laboratory tests of detonation in engine cylinders. The pictures are technical plates: a spark-plug and indicator wiring diagram, a cylinder sketch beside rows of pressure-trace oscillograms, an amplifier circuit schematic, and a sharp-peaked indicator trace; a designer could draw on their stark black-on-white line diagrams and wavy graph traces.
