Pressure Rise, Gas Vibrations and Combustion Noises During the Explosion of Fuels
This is a 1933 NASA technical report on pressure rise, gas vibrations and combustion noise during fuel explosions, issued by the NASA Technical Reports Server archive and written for engineers studying engine combustion. Its pictures are plain black-and-white oscillograph traces and graphs: wavy pressure recordings with time and pressure scales, and line plots of delay times against a lambda axis with fitted curves and data points. A designer might take the spare scientific chart layout, the hand-drawn grid lines and the dense typewritten axis labels as a model for technical diagram styling.
