Testing of CFM International's advanced 3-D Woven Resin Transfer Molding (3-DW RTM) fan is proceeding on schedule and the company will begin the second phase of ground testing with its MASCOT 2 fan demonstrator engine.
The carbon fiber, 3-D woven composite RTM (Resin Transfer Molding) fan is a foundational technology for CFM’s advanced LEAP engined scheduled to enter service in 2016.
The first full LEAP-1A engine is currently in assembly and is on track to begin ground testing this fall. The engine is scheduled to begin flight testing on GE’s modified 747 flying testbed in mid-2014, followed by engine certification the following year.
“The LEAP fan test program has been a total success thus far,” said Cedric Goubet, executive vice president of CFM International. “We have been developing this technology for nearly two decades and all of our testing has confirmed that the LEAP fan will deliver on the commitments we have made to our customers. This light-weight structure is proving to be incredibly durable and virtually maintenance free.”
This Snecma (Safran) proprietary technology has been under development for several years and will dramatically reduce engine weight while providing a more durable blade. The company launched the demonstrator program, dubbed MASCOT (Moteur à Aubes de Soufflante en Composite Taille) in 2009 and has since logged thousands of hours of testing. MASCOT is validating this revolutionary technology in a CFM-sized fan installed on a CFM56-5C engine
MASCOT 2 completed 50 hours of testing at Snecma facilities in Villaroche, France (near Paris) over a two-month period. Testing validated fan performance and fan stall and flutter margin, with the hardware meeting pre-test predictions. The next phase will include cross wind and acoustics testing at GE’s outdoor test facility in Peebles, Ohio (near Cincinnati).
