Pratt & Whitney PW1000G

The Pratt & Whitney PW1000G is a high-bypass geared turbofan engine currently selected as the exclusive engine for both the Mitsubishi MRJ and Bombardier CSeries regional jets. The project was previously known as the Geared Turbofan (GTF), and originally known as the Advanced Technology Fan Integrator (ATFI).

Development

Pratt & Whitney first attempted to build a geared turbofan starting around 1998, known as the PW8000. [ [http://www.highbeam.com/doc/1G1-20944971.html Pratt & Whitney's surprise leap.] ] This essentially was an upgrade of the existing Pratt & Whitney PW6000 that replaced the fan section with a gearing system and new two-stage fan. After several years of development the PW8000 essentially disappeared. [ [http://cornponepapers.blogspot.com/2006/04/short-life-and-untimely-demise-of.html The Short Life and Untimely Demise of the PW8000] ] Soon after the ATFI project appeared, still using the PW6000 turbomachinery but with a new gearbox and a single-stage fan.

This led to the Geared Turbofan (GTF) programme, which was based around a newly designed core jointly developed with MTU Aero Engines of Germany.

In July, 2008, the GTF was renamed the PW1000G, the first in a new line of similar engines.
