Company Says Engine Exceeded Expectations In Nearly 200 Hours
Of Testing
Initial ground testing on the first PurePower PW1000G series
engine, the PW1524G engine for the Bombardier CSeries aircraft, has
been completed by Pratt & Whitney. The company said the engine
completed nearly 200 hours of ground tests at the company's West
Palm Beach, FL. facility.
"The engine continues to exceed our expectations," said Bob
Saia, vice president, Next Generation Product Family. "We have
already completed an unprecedented amount of testing on this first
engine, including a full structural evaluation, performance, noise
and emissions testing. Testing has validated overall engine
operational characteristics including component design, rotor
dynamics and engine fuel and lubrication systems. This testing
confirmed the benefits and robustness of the Geared Turbofan™
engine that Pratt & Whitney initially established during the
2008 Demonstration Engine Program."
The first engine ran nearly three times longer than Pratt &
Whitney's legacy experience for a first engine test program. Pratt
& Whitney began ground testing of the PW1524G engine on
schedule in September. Assemblies of the second and third PW1524G
development engines are nearing completion. The second engine will
also be tested at the West Palm Beach, Fla. test facility before
being shipped to the company's Mirabel Aerospace Centre facility in
Quebec, Canada. The engine will be mounted to the Pratt &
Whitney 747 flying test bed for first test flights scheduled to
begin in mid-year. Engine certification and aircraft first
flight are scheduled for 2012.
Bombardier CSeries C110
The PurePower engine uses an advanced gear system allowing the
engine's fan to operate at a different speed than the low-pressure
compressor and turbine. The combination of the gear system and an
all-new advanced core delivers double-digit improvements in fuel
efficiency and environmental emissions as well as a 50 percent
reduction in noise.
The PurePower engine has been selected as exclusive power for
the Bombardier CSeries scheduled to enter service in 2013 and the
Mitsubishi Regional Jet scheduled to enter service in 2014.
The engine has also been selected to power the new Airbus A320neo
aircraft scheduled to enter service in Spring 2016 and the Irkut
MC-21 narrow-body jet scheduled to enter service in 2016.
