Who makes CFM International Leap-1B?
The CFM International LEAP (“Leading Edge Aviation Propulsion”) is a high-bypass turbofan produced by CFM International, a 50-50 joint venture between American GE Aviation and French Safran Aircraft Engines (formerly Snecma).

What does CFM engines stand for?
CFM is not an acronym, so it doesn’t stand for anything. The company (CFM), and product line (CFM56), got their names by a combination of the two parent companies’ commercial engine designations: GE’s CF6 and Snecma’s M56. We do this by building remarkable engines and offering dedicated services.
What does the 787 800 Max MCAS computer do?
The MCAS deflects the horizontal stabilizer four times farther than was stated in the initial safety analysis document. Due to the amount of trim the system applies to the horizontal stabilizer, aerodynamic forces resist pilot control effort to raise the nose.
How many LEAP engines are made by CFM International?
With the 737 MAX introduction, CFM delivered 257 LEAPs in the first three quarters of 2017, including 110 in the third: 49 to Airbus and 61 to Boeing, and targets 450 in the year. CFM was to produce 1,200 engines in 2018, 1,900 in 2019, and 2,100 in 2020. This is compared to the 1,700 CFM56 produced in 2016.
What kind of material is LEAP engine fan made out of?
The LEAP engine’s fan blades are manufactured from 3D woven RTM (Resin Transfer Molding) carbon fiber composite, an industry first for CFM. This technology results in fan blades that are not only lightweight but so durable that each individual blade is strong enough to support the weight of a wide-body airplane like the Airbus A350 or Boeing 787.
Which is more efficient the CFM56 or the leap?
While the LEAP is designed to operate at a higher pressure than the CFM56 (which is partly why it is more efficient), GE plans to set the operating pressure lower than the maximum to maximize the engine’s service life and reliability.
When did the CFM International LEAP 1B get ETOPS approval?
In April 2015, it was reported that the LEAP-1B was suffering up to a 5% shortfall on its promised reduction in fuel consumption. It obtained its 180-minute ETOPS approval from the U.S. Federal Aviation Authority and the European Aviation Safety Agency on June 19, 2017.
