CFM completes ground testing first LEAP engine

15 LEAP engines scheduled to go on test in 2014

DUBAI, U.A.E — 17 November 2013 — CFM International has completed testing of the first full LEAP engine with outstanding results. The LEAP-1A engine fired for the first time on September 4th, two days ahead of the schedule set in early 2010.

The engine, which was operating smoothly at full take-off thrust in a matter of hours, logged a total of 310 hours and more than 400 cycles during approximately five weeks of testing.

“We couldn’t be happier with the results we achieved,” said Cédric Goubet, executive vice president of CFM International. “The engine ran beautifully and met all of our pre-test predictions. The more testing we do, the more confident we become in the capabilities this engine will bring to the marketplace.”

In 2014, a total of 15 LEAP engines (a combination of all three models) are scheduled to be on test. Among the tests planned for next year, CFM will complete early icing tests at GE facilities in Winnipeg, Canada, as well as early endurance testing. Both the LEAP-1A and -1C configurations are on schedule for flight tests in 2014, as well.

“We still have a lot of testing ahead of us, and problems may turn up in future engines,” said Chaker Chahrour, executive vice president for CFM. “However, the point of these tests is to push the engine as hard as we can. We got a ton of great data that has given us real insight into this engine, and we are right where we want to be.

“Our goal is to identify potential problems on our test stand and fix them long before we ever install these engines on our customers’ airplanes. That’s the reason we are also doing a few certification tests early. We have every confidence in our technology but, with the fastest ramp-up in aviation history ahead of us, we have to do everything we can to make sure we get it right the first time.”

The first engine test launched an extensive ground and flight test certification program that will encompass 60 engine builds over the next three years and will accumulate approximately 40,000 cycles before entry into service.

The foundation of the LEAP engine is heavily rooted in advanced aerodynamics, environmental, and materials technology development programs. It will provide 15 percent better fuel consumption and an equivalent reduction in CO2 emissions compared to today’s best CFM engine, along with dramatic reductions in engine noise and emissions. All this technology brings with it CFM’s legendary reliability and low maintenance costs.

About CFM International

CFM International, a 50/50 joint company between Snecma (Safran) and GE, is the world's leading supplier of commercial aircraft engines, has delivered more than 25,600 engines to date. The company CFM officially launched the LEAP engine, which is its first all-new centerline engine in nearly 40 years, in 2008. The LEAP engine promises to bring double-digit improvements in fuel efficiency, emissions and noise, while the legendary reliability and low cost of ownership of its predecessor, the ubiquitous maintaining CFM56 engine family. In 2009 COMAC chose the LEAP-1C engine as the sole powerplant for the C919 in 2009; Airbus followed in 2010 when it selected the LEAP-1A engine as an option on the A320neo family; and in 2011, Boeing selected the LEAP-1B as the sole powerplant for its new 737 MAX.
