Abstract : A digital flow control system for testing ramjet engines that permits control of fuel in steps, or percentages, of full flow rate. Four cavitating venturis connected to four valves control the flow rate through the valves such that the fuel flow rate is regulated in 10% increments of full flow rate depending upon the combination of valves which are open.
