CFM56-3 life-limited engine parts
Pratt & Whitney, a United Technologies Corp. company, recently debuted the first new Pratt & Whitney Global Material Solutions (GMS)- manufactured CFM56-3 life-limited engine parts at Aviation Week's MRO US conference in Atlanta. The parts displayed include a high-pressure compressor (HPC) 1-2 spool, an HPC 4-9 spool and HPC front hub.
Pratt & Whitney GMS offers customers 48 CFM56-3 engine parts, including 19 life-limited rotating parts. The 48 GMS parts constitute approximately 90 per cent of the new material value in an average engine overhaul.
“With our 82-year history as a successful original equipment manufacturer (OEM), Pratt & Whitney is uniquely qualified to deliver a new choice in CFM56-3 engine parts,” said Matthew Bromberg, vice president and general manager, GMS. “Pratt & Whitney- manufactured CFM56-3 engine parts are being developed using the same rigorous design, verification, test and production certification processes as a new engine program.”
“We recently concluded our first engine endurance test with GMS CFM56-3 gas-path engine parts and we will complete additional engine tests and rig tests this year as a part of our FAA certification of CFM56-3 life- limited engine parts,” continued Bromberg.
P&W is testing all parts in its two validation CFM56-3 engines to ensure they meet the same design and testing standards required in an OEM certification program. To date, the two engines have logged more than 300 h and nearly 1,600 cycles. All Pratt & Whitney – engineered CFM56-3 engine parts are expected to be certified and enter the market in the first quarter 2008.
GMS, an industry-revolutionising initiative delivering OEM-quality life- limited and gas-path parts for the CFM56-3 engine at a competitive price, was announced in February 2006.
