Pratt & Whitney Geared Turbofan™
Engine Cleared for First Flight
New engine targets double-digit improvements in fuel burn,
environmental emissions and engine noise making it the greenest jet
engine available today
EAST HARTFORD, Conn. (Business Wire EON/PRWEB ) July 3, 2008 --
Pratt
& Whitney’s Geared
Turbofan [GTF]
demonstrator engine has completed Phase II ground tests and has been
cleared for flight testing.
In a GTF
engine, a state-of-the-art gear system allows the engine’s
fan to operate at a different speed than the low-pressure compressor and
turbine, resulting in greater fuel efficiency and a slower fan speed for
reduced noise.
In 2007, the GTF
was selected
as the exclusive power for the new Mitsubishi
Regional Jet and the proposed Bombardier
CSeries.
News Facts:
-
More than 12% reduction in fuel burn at an engine level, when
installed on a next generation aircraft the savings is an average of
413,000 gallons per year.
-
More than 12% reduction in CO2 emissions, equal to 3,000 fewer tonnes
of CO2 per aircraft, per year
-
50% reduction in NOx emissions, a leading contributor to smog and air
quality
-
50% reduction in engine noise, which is 20 dB quieter than the
strictest noise standards introduced this year.
-
Double-digit reductions in overall operating costs equal to more than
$1.5 million in cost savings per aircraft, per year
Quotes:
“The ground test program has been a complete
success and the Geared
Turbofan engine has met or exceeded all performance targets. This
demonstrator engine has confirmed the laboratory results of our Fan
Drive Gear System demonstrating excellent efficiency and operational
characteristics.”
“The double-digit reductions in fuel burn,
engine noise, environmental emissions and operating costs we’ve
targeted make the Geared
Turbofan engine the best solution for the next generation of
commercial aircraft.”
