The Pratt & Whitney PW1000G, also called the GTF (geared turbofan), is a high-bypass geared turbofan engine family produced by Pratt & Whitney. After many demonstrators, the program was launched with the PW1200G on the Mitsubishi SpaceJet (later cancelled) in March 2008, first flight tested in July 2008. The first variant to be certified was the PW1500G for the Airbus A220 in February 2013. The program cost is estimated at $10 billion. The gearbox between the fan and the low-pressure spool allows each to spin at its optimal speed, allowing a higher bypass ratio for a better propulsive efficiency. Pratt & Whitney claims the engine is 16% more fuel efficient than the previous generation, and up to 75% quieter. The first variant to enter service was the PW1100G for the Airbus A320neo in January 2016. The engine had teething problems after its introduction, extending to grounded aircraft and inflight failures, solved afterwards. The variants can generate 15,000 to 33,000 lbf (67 to 147 kN) of thrust. The engine is used on the A220, A320neo family, Embraer E-Jet E2 and Irkut MC-21. More information...
