Profitable Transport Engines for the Environment of the Eighties

This paper assesses the impact of meeting the environmental requirements for reduced noise and air pollution on the cost and technical design considerations for engines to power the next generation of commercial transport aircraft. Engine candidates studied are in the advanced (new) design class as well as derivatives of existing high-bypass turbofan engines which offer attractive total cost of ownership features. The elements of operating cost are analyzed for the effect of the engine on aircraft economics, with special attention being given to operating cost differences between new engines and those derived from current in-service high-bypass engines.
