Engine Plumbing Diagram

This is a sample of a typical test bed plumbing diagram for a ramjet engine test ...usually these layouts were hand drawn in multiple sections and left for the artist to re layout on the computer with the appropriate nomenclature and symbols. Also these were typically in two formats, one for manual presentation in black and white and the other in a color coded format showing different colors to represent the different fuels, oxidizers, hydraulic, controller channels and various wiring configurations.
