WASHINGTON, D.C., June 24, 2010 – The Federal Aviation Administration
(FAA) announced today that Pratt & Whitney has been awarded a one-year
contract with extension options, which will assist Pratt & Whitney to
further develop and mature new jet engine technologies aimed at reduced
fuel burn, noise and emissions under the FAA’s Continuous Lower Energy,
Emissions and Noise (CLEEN) technology development program.  The funding
will support ongoing development of advanced technologies for the new
game-changing PurePower engine family with the geared turbofan(tm)
architecture.  Pratt & Whitney is a United Technologies Corp. (NYSE:UTX)
company.
Under the CLEEN program, the FAA will support the development and
commercialization of CLEEN technologies for current and future civil
subsonic airplanes and jet engines to help achieve the Next Generation
Air transportation System (NextGen) goals.  These goals are intended to
increase airspace system capacity by significantly reducing the impact
of noise and air quality emissions on communities.
The CLEEN program’s goals include the maturation of new aircraft
technologies for introduction  beginning in 2015.  The goals include
reduction of aircraft fuel burn by 33 percent below current technology,
reduction of noise by 32db cumulative below Stage 4 levels, and
reductions of NOx emissions by 60 percent below CAEP 6 standards.  Pratt
& Whitney will work to further advance jet engine technologies to
achieve additional fuel, emissions and noise benefits through 2025.
“The PurePower PW1000G(r) engine, which is scheduled for entry into
service in 2013, already enables Pratt & Whitney to deliver world class
levels of fuel burn, noise, and emissions,” said Alan Epstein, Pratt &
Whitney vice president, Technology & Environment.  “Unlike conventional
turbofans based on existing technology that have been stretched to its
limits to achieve added efficiencies, the geared turbofan engine
technology has runway and should achieve fuel burn savings of 25-35
percent by the 2020s.  The gear changes everything.”
The PurePower family of engines is designed to power the next generation
of passenger aircraft.  The combination of its gear system and advanced
core allows PurePower engines to deliver double-digit improvements in
fuel efficiency and emissions with a 50-percent reduction in noise over
today’s engines.
