This study investigates the feasibility of using a low cost can combustor in a subsonic ramjet engine in the flight envelope of Mach 0.7 to 0.9, altitude 20,000 to 30,000 feet. A simple can combustor without close fabrication tolerances was designed and fabricated. The can was installed in a subsonic ramjet which was ground tested in a direct-connect pipe set-up. The combustion efficiency and thrust were determined at conditions representative of the flight envelope. These results are compared with results of a model subsonic ramjet engine cycle analysis. The end result of the program is a developed combustor system for a subsonic ramjet which is an inexpensive and attractive propulsion device for one-mission remotely piloted vehicles and target drones.
