Abstract : The article describes a way of making turbofan engines by the use of well-designed turbojet engines and discusses the efficiency of such a conversion. The use of an afterburner in a turbofan engine, permitting the use of these engines at high supersonic flight speeds, is also discussed. The author cites specific English and American aircraft now using turbofan engines. A diagram of the X353-5 turbofan engine with a high by-pass ratio is shown; this engine is intended for the XV-5A VERTOL airplane. Turbofan engines with afterburners are being mounted in test aircraft. The author discusses performance of such engines. Future tactical aircraft and the type of engine required for their missions are described. Replacing of kerosene with liquid hydrogen is considered. The importance of reducing the weight of engines in order to increase the capability of airplanes is stressed. (Author)
