THE PUREPOWER ENGINE CHANGES EVERYTHING:
NOT THE SAME OLD TURBOFAN

Pratt & Whitney’s PurePower PW1000G engine is not just a concept or a promise for the future—it is reality. With 20 years of research and development, component rig testing on all major modules and extensive ground and flight testing of a full-scale demonstrator engine complete, the PurePower PW1000G engine with Geared Turbofan technology will deliver game-changing reductions in:

• Fuel burn
• Environmental emissions
• Engine noise
• Operating costs

In the PurePower PW1000G engine, 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 May 2008, Pratt & Whitney’s full-scale demonstrator engine completed a ground test program of more than 250 hours, with engine performance and noise levels—and fan-drive gear system reliability—meeting or exceeding all pretest predictions. The PurePower PW1000G demonstrator engine took to the skies for the first time in July 2008 on Pratt & Whitney’s 747SP flying testbed . Further flight tests were conducted on an Airbus A340-600 aircraft.  The PurePower PW1000G engine completed its rigorous 400-hour ground and flight test program with test results that indicate the engine will deliver the performance and efficiency targets of this revolutionary technology.

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. 

Mitsubishi Aircraft Corporation has selected the PurePower PW1000G engine as the exclusive power for the next-generation Mitsubishi Regional Jet (MRJ). The PurePower PW1000G engine has also been named as the sole propulsion system for the Bombardier CSeries mainline aircraft.  Russia’s Irkut Corporation has selected the Pratt & Whitney PurePower® PW1000G engine to power the Irkut MC-21 aircraft.  The MC-21 program will allow Pratt & Whitney an opportunity to extend its PW1000G engine models to the 30,000 pound thrust class.

OPERATIONAL AND ENVIRONMENTAL BENEFITS DELIVERED FASTER EQUAL A COMPETITIVE ADVANTAGE

With industry-leading technology, extensive rig testing and flight testing with a full-scale demonstrator engine, Pratt & Whitney’s PurePower PW1000G engine redefines engine performance with double-digit reductions in fuel consumption, CO2 and NOx emissions, engine noise and operating costs. But being the first to deliver these game-changing advances isn’t enough—Pratt & Whitney is committed to maintaining its leadership, with technology plans already in development to continually build on the benefits of the PurePower PW1000G performance advantage beyond its 2013 service entry.
