PurePower Engine Flight Tests

Pratt & Whitney PurePower™ PW1000G Engine

Pratt & Whitneys 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 engines 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 engines 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 & Whitneys 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 & Whitneys 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. Both applications of the PurePower PW1000G engine family are scheduled to enter service in 2013.

With industry-leading technology, extensive rig testing and a full-scale demonstrator engine, Pratt & Whitneys 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 isnt 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.

Wow the video for this engine is EPIC it's like the engine will blow up the world !

[4yall]

nooooooooooooooo... I love big noisy engines :(....

[hangarrat101]

Moron. What a great name for an airbase :)

thats the weather man, egghead

Good vid!

[rudyyoungblood2223]

that engine looks quite out of place on the a340... surely it wud have been better to try it on a 737 or a320

[ehwhinn]

well they wer talking about the noise that can be heard in public when the aircraft passed by...for us working on the airport specially wrkin on the airplane,still we need PPE's..

[type2mike]

Fantastic. I hope they can someday make GTFs for widebody aircraft as well. Bravo P&W!

Apparently the point at 0:30 is that with 50% less noise, you only need minimal hearing protection?!
