Atomization of liquid fuels. Part II
This is a 1925 NACA technical memorandum from the NASA Technical Reports Server, issued for aeronautical engineers studying how liquid fuel breaks into droplets in injection nozzles. The pictures are plain line diagrams and graphs: scatter-and-curve charts of drop diameter against atomization pressure for kerosene and gas-oil, a shutter assembly drawing, and an enlarged fuel nozzle cutaway with its slotted atomizer tips. A designer could take the sparse engineering linework and the precise dimensioned layouts as a model for technical schematic diagrams.
