Development of an Impinging-jet Fuel-injection Valve Nozzle
This is a 1931 NASA technical report on developing an impinging-jet fuel-injection valve nozzle, issued by the National Advisory Committee for Aeronautics for engine researchers and aeronautical engineers. Its pictures are black-and-white photographs and line drawings: spray sequences of fuel jets emerging from a nozzle, an apparatus with pressure gauges and a gas cylinder, and a grid chart plotting penetration against time, offering a designer sparse, technical imagery of motion, spray and measurement equipment.
