Pratt & Whitney Partners with NASA to Create Green Future for Aviation

IASA: Nachhaltige Luftfahrt - Sustainable Aviation

Working on engines producing up to 75% fewer emissions

East Hartford, CT, February 23, 2017:  Pratt & Whitney has been chosen by NASA’s Aeronautics Research Mission Directorate to be a part of NASA’s Ultra-High Bypass Advanced Nacelle Technologies Flight Demonstration. The goal of the partnership is to develop engines for commercial airliners that produce less pollution and are more fuel-efficient.
This is not the first time that Pratt & Whitney has worked with NASA to advance green engine technologies. The two organizations partnered a number of times during the 1990s and 2000s, and together, they have made significant advancements in fuel-efficient technologies. A project in the 1990s through NASA’s Advanced Subsonic Technology program led to the development of base technology for fuel-efficient fans. Another partnership in 2005 through the Space Act Agreement gave Pratt & Whitney access to NASA expertise and facilities for engine testing.
The most notable result of the P&W-NASA partnership is the development of technology for the PurePower® Geared Turbofan™ (GTF) family of engines. The GTF engine improves efficiency by over 16 percent and increases fuel savings while dramatically reducing noiseby 50 percent, a profound advancement for the aeronautics industry. The success of the partnership between the two organizations, particularly the development of technology for the GTF, has created even more opportunities for collaboration.
Pratt & Whitney is currently working with NASA on the ‘New Aviation Horizons’ initiative, through which a new generation of revolutionary “X-planes” featuring advanced technologies will be designed, built and tested over a 10-year period.
Pratt & Whitney engines are included on four out of five of the experimental aircraft designs. According to NASA, the project aims “to develop aircraft that use 50 percent less fuel, produce 75 percent fewer emissions, and are notably more quiet than today’s vehicles.” Pratt & Whitney is making large contributions to this initiative that aims to have futuristic aircrafts in the sky as soon as the 2020s.
With the new three-year Ultra-High Bypass Advanced Nacelle Technologies partnership, Pratt & Whitney, UTC Aerospace Systems and Boeing will look to build on the innovations of the past, and develop the physics for a new generation of GTF engines that will be even more efficient and quiet. With technologies based on the learning developed through this partnership, the goal is to improve efficiency by another 10 percent above the 16 percent efficiency improvement from the first generation GTF engines. 
“The goal is to build on the legacy of our partnership with NASA to work on improving our geared turbofan engine technologies,” said Michael Winter, senior fellow, Advanced Technologies, Pratt & Whitney. “Our work with NASA will help us extend the technology and move deeper into the design space.”
This partnership will likely have a large impact on the future of our world. With new advancements from this partnership, we may see the environmental cost of air transport reduced as a result of increased fuel savings, or home and business owners near airports no longer negatively affected by the constant roar of airplanes overhead.
“This partnership is not only good for our business, but for the planet,” Winter said. “Our ability to technically differentiate our products while also doing good for our world defines the legacy we leave. As engineers, what more could we hope for?”

Pratt & Whitney Announces Site for GTF Maintenance

IASA: Nachhaltige Luftfahrt - Sustainable Aviation

East Hartford, Conn., June 30, 2016: Pratt & Whitney announced a $65 million investment in its engine overhaul facility in Columbus, Georgia, to perform maintenance on PurePower® Geared Turbofan™ (GTF) engines. The Columbus Engine Center, located 90 miles south of Atlanta, is the first facility in the world to begin maintaining PW1000G engines. It will maintain PW1100G-JM and PW1500G engines, in addition to V2500, PW2000, F117 and F100 engines. The center’s new GTF engine facilities will include disassembly, inspection, assembly and test capability. Construction of a new test facility will start this year.

FAA Certifies Pratt & Whitney’s PurePower® PW1400G-JM Engine to Power Irkut’s MC-21 Aircraft

Hartford, Conn., Monday, May 9, 2016: The FAA has certified Pratt & Whitney’s PurePower PW1400G-JM engine to power Irkut’s MC-21 aircraft. With this milestone, Pratt & Whitney now has three certified PurePower Geared Turbofan™ (GTF) engine variants.  “This milestone is another huge step forward for the PurePower engine program, which brings unmatched operational benefits including double-digit reductions in noise, emissions and fuel burn, making for greener skies,” said Greg Gernhardt, president, Commercial Engines Programs, Pratt & Whitney. “The technology behind the GTF engine is a game-changing force in the aviation industry for all the right reasons and we are excited that the PW1400G-JM engine is moving one step closer to powering Irkut’s MC-21 aircraft and providing the renowned benefits for which this engine is so highly regarded.” “We would like to congratulate Pratt & Whitney on the certification approval of its PurePower engine, which will be installed on МС-21 Family Aircraft,” said Oleg Demchenko, president, Irkut Corporation.

“The engine increases the competitiveness of our aircraft since it offers tangible cost savings to our airline customers due to the enhanced fuel burn efficiency while simultaneously benefitting the environment.”

Up to now, the PurePower engine family has completed more than 58,000 cycles and 35,000 hours of testing.

Pratt & Whitney’s PurePower® Geared Turbofan™ Engine Cited as an ‘Aviation Climate Solution’

East Hartford, Conn., September 30, 2015: Pratt & Whitney’s PurePower® Geared Turbofan™ (GTF) engine was cited as an ‘Aviation Climate Solution’ by the Air Transport Action Group (ATAG) at the Global Sustainable Aviation Summit in Geneva, Switzerland.

The GTF’s engine technology reduces commercial aircraft fuel burn and carbon dioxide emissions by more than 16 percent, reduces regulated emissions by more than 50 percent and will reduce CO2 emissions at a level equivalent to planting nearly 1 million trees or removing 3 million cars off the road – every year. The engine reduces the aircraft noise footprint by more than 75 percent. Five airframers have chosen the GTF engine to power their new aircraft or re-engine existing models.

Pratt & Whitney’s GTF is included as part of the ‘Aviation Climate Solutions’, a collection of 100 examples of collaboration within the aviation industry to cut carbon dioxide emissions and help reduce its impact on climate change.

“Aviation plays a vital role in the world economy, providing connectivity for people and business,” said Michael Gill, executive director, ATAG. “Our industry has also taken a lead in climate action, putting in place a comprehensive framework and goals to reduce emissions from air transport. The Aviation Climate Solutions are a set of case studies showing how different parts of the industry all over the world, including Pratt & Whitney are working together to reduce our climate impact.”

‘Aviation Climate Solutions’ was released at the Global Sustainable Aviation Summit in Geneva, Switzerland, alongside an open letter from industry chief executives that reaffirms the industry’s commitment to climate action and calls on governments to support it with the development of a global market-based measure for aviation emissions, improved efficiency in air traffic management and accelerating research for alternative fuels and new technology.

Pratt & Whitney is committed to identifying, developing and incorporating new technologies that reduce the environmental impact of its products and services worldwide.

“The PurePower Geared Turbofan engine provides immense value to the future of sustainable aviation,” said Dr. Alan Epstein, Pratt & Whitney’s vice president, Technology and Environment. “Its development spurred a new period of innovation among commercial aircraft manufacturers.”

In 2008, the aviation sector became the first to set global goals to proactively manage its climate change impact. The industry will stabilize its net CO2 emissions from 2020 through a concept called carbon-neutral growth, whereby traffic would continue to rise to meet social and economic demands, but growth would be offset through a global market-based measure. The longer-term goal is to reduce net CO2 emissions from aviation to half of what they were in 2005, by 2050.

ATAG is a coalition of organizations and companies throughout the air transport industry that drive the sustainable development of the air transport sector. Pratt & Whitney is a funding member.
