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.
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.
CFM International announced the RISE program in June 2021 as an intended successor of the CFM LEAP turbofan engine, with plans to enter service in the mid-2030s. At the 2022 Farnborough Airshow in July of that year, CFM International and Airbus announced plans to start flight tests for the RISE engine on an Airbus A380-based testbed in 2026.
