Abstract : The attributes of the low-volume ramjet and the solid-fuel ramjet engines were analyzed. The analysis considered the application of these ramjet engine concepts to the ARM 1 and ARM 2 air-to-surface antiradar missiles. Optimum ramjet engine designs were developed for each. Comparative missile designs utilizing both solid and liquid propellant rocket engines were made. Computer simulation programs were developed for each missile and propulsion combination. The mission performance of each was then determined by simulating typical attack trajectories. The results showed that the low-volume ramjet achieved, by a wide margin, the longest usable range in both missile systems. The solid-fuel ramjet failed by a significant margin to match the range performance of comparative rocket systems. (Author)
