A discussion of the flow mechanism in an afterburner extension to ram-jet engine is presented. Analysis indicated that with an afterburner, ram-jet performance equal to that of the engine equipped with a variable-geometry converging exit nozzle could result. The use of an afterburner requires, under some conditions, heat addition to a supersonic stream.
