MIDDLETOWN, Conn. - Pratt & Whitney has completed assembly on the first PurePower PW1217G geared turbofan engine for use in testing for the new Mitsubishi Regional Jet (MRJ) aircraft. The engine, rated at 17,000 pounds of thrust, is the third PurePower PW1000G series engine to complete assembly. It is to be delivered to Pratt & Whitney's West Palm Beach, Fla., facility to initiate testing.
"The PurePower engine is an integral part of the new Mitsubishi Regional Jet," said Yukihiko Nakata, Mitsubishi Aircraft Corp. senior deputy project manager. "We continue to work closely with Pratt & Whitney to integrate the engine with the airframe, and we look forward to getting the initial test results from this first engine to test."
The PW1200G engine test program will run a total of eight test engines over the next 24 months. Entry into service is scheduled for 2014. Mitsubishi has sold MRJ aircraft to All Nippon Airways and Trans States Holdings.
Pratt & Whitney recently completed initial ground testing of its first PW1000G series engine with nearly 200 hours of testing. PurePower engine core testing concluded in 2010 with more than 260 accumulated test hours. In addition to the core testing, Pratt & Whitney has performed module-level testing for the PurePower engine program, including fan drive gear system testing with simulations of more than 60,000 takeoffs and landings, and hundreds of hours of testing on the low- and high-pressure compressor.
