The geared turbofan (GTF) is Pratt & Whitney’s “game changing” stake in the future of propulsion for the coming new generation of single-aisle aircraft that will eventually replace the Boeing 737 and Airbus A320. Mindful, however, of the Superfan fiasco in 1986 (in which IAE attempted to develop a geared fan engine for the Airbus A340) and its problems with the PW6000, the company is being careful not to put all of its eggs in one basket and is therefore developing what it calls the advanced turbofan (ATF) in parallel.
