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 company is a joint venture between GE Aerospace and Safran Aircraft Engines (formerly known as Snecma) and is headquartered in Cincinnati, Ohio. It was founded in 1974 to build and support the CFM56 series of turbofan engines. CFM is the world's largest commercial aircraft engine manufacturer, with a 39% market share as of 2020. [1]
Equipped with CFM International LEAP-1C28 engines, each rated of 29,220 pounds (129.98 kN) of take off thrust (MTOT) and 127.93 kN of max continuous thrust (MCT). [ 79 ] [ 80 ] In September 2023, COMAC Chairman He Dongfeng revealed, however, that shortened and extended variants of the C919 would also be built, covering a range from 130 to 240 ...
Its joint venture with Safran, CFM International, makes the LEAP engine the sole engine on the Boeing 737 MAX and one of two provided on the Airbus A320 neo family.
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 ...
Research into the next generation of commercial jet engines, high-bypass ratio turbofans in the "10-ton" (20,000 lbf; 89 kN) thrust class, began in the late 1960s. Snecma (now Safran), who had mostly built military engines previously, was the first company to seek entrance into the market by searching for a partner with commercial experience to design and build an engine in this class.
