A ramjet is similar to a jet engine with the compressor removed. Supersonic flight provides enough compression that a compressor is not needed. Please make note that a ramjet engine will not provide static thrust, and thus will not accelerate a vehicle from a standing position. It is best suited for supersonic flight between Mach 3.5 and Mach 6. At Mach 6 a scramjet is necessary. And finally, the purpose of the flameholder is to stabilize the flame. The fuel injector does the mixing. -Dennis
