Joint Design Of Pratt & Whitney And MTU Aero Engines
Pratt & Whitney has launched
testing of a full-scale PurePower engine core, marking a major
milestone in the development of the new generation of jet engines.
The engine core -- which consists of an ultra-efficient high
pressure compressor, a low-emissions combustor, and an all new high
pressure turbine -- was designed jointly by Pratt & Whitney and
MTU Aero Engines. The companies designed the PurePower family of
engines for large business jets, regional aircraft and the next
generation of narrow-body jets.
"The PurePower family of engines shares a common, advanced core
across the PW800 and PW1000G Geared Turbofan engine models," Bob
Saia, vice president, Next Generation Product Family, Pratt &
Whitney, said in a news release Monday. "The PurePower engine core
testing -- combined with hundreds of hours of ground and flight
testing accumulated on the PW1000G Geared Turbofan demonstrator
engine -- advances the maturity of this technology and brings us
significantly closer to final validation and certification."
The engine core testing includes more than 1,200 individual
measurements and leverages state of the art testing technologies,
allowing Pratt & Whitney engineers to perform a broad scope of
tests beyond what is normally possible at this stage of
development. The core program aims to evaluate engine performance,
operability and structural design characteristics of these key
modules.
"This successful first run of the PurePower engine core marks a
major step toward bringing an all-new, next generation engine to
market," said Dan Breitman, vice president, PW800 Programs, Pratt
& Whitney Canada. "The PurePower family of engines will deliver
double-digit reductions in fuel burn, environmental emissions and
engine noise making these products the most environmentally
responsible in their class. The goal of this core testing is to
validate the engine's design and confirm our efficiency
targets."

The PW1000G Geared Turbofan engine has been selected as
exclusive power for the Mitsubishi Regional Jet scheduled to enter
service in 2014 and the Bombardier CSeries aircraft scheduled to
enter service in 2013. After announcing the launch of these two new
aircraft programs, Mitsubishi and Bombardier each have announced
the receipt of a number of orders for these new models of aircraft.
The PW1000G was also recently selected to power the proposed new
Irkut MC-21 narrow-body jet scheduled to enter service in 2016. The
PurePower PW800 engine is targeted to power the next generation of
large business jets.
