Abstract
THE bypass or ducted-fan turbojet engine is a highly controversial aircraft powerplant. It is hoped that this presentation of its operating principles will lead to a more rational understanding of the pros and cons of the issue. Discussion is explicitly limited to transport aircraft applications at speeds in the neighborhood of 500 mph.
Noise, duct losses, boundary-layer intake, and structural considerations are all shown to be important.
It appears that a comprehensive design development of bypass or ducted-fan engines in connection with aircraft aerodynamics and structure poses a serious problem in the field of high-subsonic-speed transport aircraft.
