The CFM International LEAP ("Leading Edge Aviation Propulsion") is a high-bypass turbofan engine produced by CFM International, a 50–50 joint venture between American GE Aerospace and French Safran Aircraft Engines. It is the successor of the CFM56 and competes with the Pratt & Whitney PW1000G to power narrow-body aircraft.
Jet engine maker CFM International said on Friday aviation regulators in the United States and Europe have certified a "more durable" high-pressure turbine kit for its LEAP-1A engines that power ...
The first LEAP began ground testing at GE's Peebles (Ohio) facility in September 2013, then at Snecma’s plant in Villaroche the following year. The LEAP-1C is the first of the family to begin flight testing on a modified GE Boeing 747-100. In 2021, the CFM International partnership has been renewed until 2050 and extended to include services.
