Airfoil Stress Measurements, Performance, Noise, And Emissions
All Evaluated
Ground testing of Pratt & Whitney's first PW1200G family
engine – the PW1217G engine for the Mitsubishi Regional Jet
(MRJ) – recently concluded. The engine, the first of an
eight-engine validation and certification program, completed more
than 300 hours and 1,100 cycles. "We have successfully validated
the overall design of the PW1200G engine since starting our test
program in April. After completing airfoil stress measurements, we
conducted testing to confirm performance, noise and emissions,"
said Bob Saia, vice president, Next Generation Product Family. "We
are very pleased with these initial test results demonstrating that
the design is on track to meet our commitments to Mitsubishi. This
engine also ran cyclic endurance testing just prior to returning to
our Connecticut facility for inspection and re-build for its next
test program."

The PW1217G engine test program will run a total of eight test
engines through 2012 leading up to aircraft first flight. Entry
into service is scheduled for 2014.
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.
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 powering the
first A320neo aircraft scheduled to enter service in 2015, as well
as the Irkut MC-21 narrow-body jet scheduled to enter service in
2016.
