Pratt & Whitney Powerplant Selected For The Mitsubishi
Regional Jet
Ground testing of Pratt & Whitney's first PW1200G family
engine -- the PW1217G engine for the Mitsubishi Regional Jet (MRJ)
-- is well under way. The engine, the first of an
eight-engine validation and certification program, has completed
nearly 16 hours of testing.

Over 2,000 pieces of instrumentation are used to support design
validation of key low rotor components. Testing of this first
PW1217G engine is expected to last through mid- year. In addition
to this engine, a PW1217G test core will soon begin stress testing
in the Pratt & Whitney West Palm Beach facility to further the
design validation of high rotor components. Three additional
PW1217G engines are in various stages of build and will begin
testing shortly.
"We are very pleased with the initial results from the PW1217G
engine test. It is meeting our pre-test expectations," said Bob
Saia, vice president, Next Generation Product Family. "We have
incorporated lessons learned from extensive development and testing
of the Geared Turbofan™ engine architecture demonstrating
unprecedented technology readiness before the engine ran for the
first time."
The PW1217G engine test program will run a total of eight test
engines over the next two years with engine certification and
aircraft first flight scheduled for 2012. Entry into service is
scheduled for 2014. All Nippon Airways and Trans State Holdings
have placed firm and option orders for a total of 125 Mitsubishi
Aircraft Corporation MRJ aircraft.
Pratt & Whitney says 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.
The PurePower engine also has been selected as exclusive power
for the Bombardier CSeries aircraft scheduled to enter service in
2013 and to power the Airbus A320neo aircraft family scheduled to
enter service in 2015, as well as the Irkut MC-21 narrow-body jet
scheduled to enter service in 2016.
