Pratt & Whitney’s PurePower® PW1000G Engine
Family is not just a concept or a promise for the
future—it is reality.
The PurePower Engine changes everything—it's not the same old turbofan
With 20 years of research and development, component rig testing on all major modules, extensive ground and flight testing of a full-scale demonstrator engine complete and extensive ground and flight testing of its first two engine series well underway, the PurePower PW1000G engine with Geared Turbofan™ technology delivers game-changing reductions in:
- • Fuel burn
- • Environmental emissions
- • Engine noise
- • Operating costs
In the PurePower PW1000G engine family, a state of the art gear system separates the engine fan from the low pressure compressor and turbine, allowing each of the modules to operate at their optimum speeds. This enables the fan to rotate slower and while the low pressure compressor and turbine operate at a high speed, increasing engine efficiency and delivering significantly lower fuel consumption, emissions and noise. This increased efficiency also translates to fewer engine stages and parts for lower weight and reduced maintenance costs.
The PurePower PW1000G engine’s fan-drive gear system is just one component of this next-generation engine. The PurePower PW1000G engine also incorporates advances in aerodynamics, lightweight materials and other major technology improvements in the high-pressure spool, low-pressure turbine, combustor, controls, engine health monitoring and more.
Technology that is shaping the future of aviation today
Pratt & Whitney has been actively testing all key components of the PurePower PW1000G engine family, with 16 technology rigs running around the world. In 2008, Pratt & Whitney’s full-scale demonstrator engine completed its rigorous 400-hour ground and flight test program with test results that indicated the engine delivers the performance and efficiency targets of this revolutionary technology. Hundreds of hours of ground testing of the first PW1500G engines for the Bombardier CSeries and PW1200G engines for the Mitsubishi Regional Jet further validate the engine family’s many benefits.
Pratt & Whitney’s PurePower PW1000G engine has been recognized by Popular Science Magazine with a 2009 “Best of What’s New Award.” In addition to the Popular Science award, Pratt & Whitney’s PurePower engine family also received the 2009 Aviation Week Laureate Award for outstanding achievement in Aeronautics and Propulsion and the 2008 Technology Breakthrough Award from the China Aviation Association and AVIC Science and Technology department.
The PurePower engine has been selected as exclusive power for the Mitsubishi Regional Jet (MRJ) and the Bombardier CSeries. It has also been selected by Russia’s Irkut Corporation to power the Irkut MC-21 aircraft. In 2011, Airbus announced it will offer Pratt & Whitney’s award-winning geared turbofanengine as an ultra-fuel-efficient new engine option (neo) for its A320neo family of aircraft. Most recently, Embraer selected the PurePower engine as the exclusive power for its new second generation of the E-Jet aircraft family.
