WebMay 10, 1993 · A combined turbofan and ramjet aircraft engine includes a forward bypass duct which allows the engine to operate more efficiently during the turbofan mode of operation. By mounting a ramjet preburner in the forward duct and isolating this duct from the turbofan bypass air, a transition from turbofan operation to ramjet operation can take … WebIt produces thrust from the exhaust, and it produces shaft power from the turbine. A turbojet uses this shaft power to drive the compressor and to pull in enough air to feed the engine. A turbofan, however, pulls in extra air, i.e. the bypass air, and shoots it out the back, thereby essentially using shaft power to produce more thrust.
