Pratt & Whitney PurePower® PW1000G Engine

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 ground and flight testing of a full-scale demonstrator engine, the PurePower PW1000G engine is already proving its ability to 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 allows the engine’s fan to operate at a slower, optimum speed while freeing the low-pressure compressor and turbine to operate at their optimized higher 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 maintenance cost.

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.

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 aircraft and will continue flight-testing through yearend on the 747 and then an Airbus A340-600 aircraft.

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.

With industry-leading technology, extensive rig testing and a full-scale demonstrator engine, Pratt & Whitney’s PurePower PW1000G engine is on track to redefine 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 place to continually build on the PurePower PW1000G performance advantage beyond its 2013 service entry.
