The turbofan is a gas turbine engine variant that exploits the use of a shrouded fan to deliver high performance in the high subsonic to low supersonic flight application range. Parameters critical to turbofan performance include the bypass ratio, which sets the fan’s size relative to the engine core. Cycle analysis for a separate-stream engine is covered in some detail in this chapter. Cycle analysis for a mixed-stream engine is also presented. Engine health monitoring as a means for preventing costly engine failures is discussed. Environmental issues related to aircraft engine usage, such as noise, pollution and dwindling fuel supplies, are brought into focus in the final portion of the chapter.
