The Pratt & Whitney PW1000G is a high-bypass geared turbofan engine family, currently selected as the exclusive engine for the Bombardier CSeries, Mitsubishi Regional Jet (MRJ), and Embraer's second generation E-Jets, and as an option on the Irkut MC-21 and Airbus A320neo. The project was previously known as the Geared Turbofan (GTF), and originally the Advanced Technology Fan Integrator (ATFI). The engine is expected to deliver reductions in fuel use and ground noise when used in next-generation aircraft. The PW1000G engine first entered commercial use in January 2016 with Lufthansa's first commercial Airbus A320neo flight.
Pratt & Whitney first attempted to build a geared turbofan starting around 1998, with the PW8000. This essentially was an upgrade of the existing PW6000 that replaced the fan section with a gearing system and new single-stage fan. After several years of development the PW8000 essentially disappeared.
Soon afterwards the ATFI project appeared, using a PW308 core but with a new gearbox and a single-stage fan. It had its first run on March 16, 2001. This led to the Geared Turbofan (GTF) program, which was based around a newly designed core jointly developed with German MTU Aero Engines.
In addition to the geared turbofan, the initial designs included a variable-area fan nozzle (VAFN), which allows improvements in propulsive efficiency across a range of the flight envelope. However, the VAFN has since been dropped from production designs due to high system weight.
In July 2008, the GTF was renamed PW1000G, the first in a new line of "PurePower" engines. Pratt & Whitney claims the PW1000G is 16% more fuel efficient than current engines used on regional jets and single-aisle jets, as well as being up to 75% quieter.
The engine was first tested on the Pratt & Whitney Boeing 747SP, then since October 14, 2008 on an Airbus A340-600 in Toulouse on the number two pylon. Testing of the CSeries bound PW1524G model began in October 2010. The PW1500G engine successfully achieved Transport Canada type certification on February 20, 2013. The A320 engine, the PW1100G, was first tested on the 747SP on 15 May 2013.
