LEAP-1A First Engine To Test

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.
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.
