The CFM LEAP family represents the engines of choice for the next-generation single-aisle aircraft. The LEAP-1A is an option on the Airbus A320neo; the LEAP-1B is the exclusive powerplant for the Boeing 737 MAX; and the LEAP-1C is the sole Western powerplant for the COMAC C919. These engines had garnered more than 8,000 operates from more than 50 customers across the globe.
about LEAP Engines
LEAP-1A: 24,500 – 32,900 POUNDS THRUST
LEAP-1B: 23,000 – 28,000 POUNDS THRUST
LEAP-1C: 27,980 – 30,000 POUNDS THRUST
PROVEN
CFM and its parent companies have fielded more new engines, engine upgrades, new technologies, and have more field experience as measured in engine flight hours than anyone else. Performance and technology is better proven than promised.
BREAKTHROUGH
Performance advancements are driven by appropriate application of new technology throughout an engine. Success in development of new technology requires the combination of both consistent investment and opportunities for commercial application.
Two engine families have contributed significantly to the design of the LEAP engine, the CFM56 and the GE90/GEnx series of engines. The GE90/GEnx contributed the high-efficiency core architecture to minimize fuel consumption, while the CFM56 legacy drove reliability and maintenance cost design practices. At entry into service in 2017, it is estimated that the GE90/GEnx architecture will have generated 80 million flight hours of revenue service, while the CFM56 family will have over 700 million flight hours of experience. The LEAP engine family offers proven, material advantages over any other engine, with 550,000 hours of proven experience with 99.98% reliability, and 22,000 engines delivered on-time and on-spec.
The CFM LEAP pedigree ensures with confidence the ability to deliver a 15% improvement in fuel efficiency, as compared to the CFM56-7BE, while maintaining the same level of dispatch reliability and life-cycle maintenance costs as the CFM56-7BE. With its simple architecture and $2 billion annual investment in technology, the LEAP engine family offers the lowest cost and highest revenue-generating ability, saving an estimated nearly $3 million per plane.
This is CFM, proven performance, low execution risk, and the application of advanced technology both at entry into service and throughout an engine’s life cycle.

DID YOU KNOW?
The LEAP engine will be the first to introduce Ceramics Matrix Composites into commercial service. The engine will feature a CMC shroud in first stage of the high-pressure turbine.
It takes 150,000 miles of carbon fiber to create on LEAP fan blade. One LEAP fan blade is so strong, it can support the weight of a wide-body airplane like the Airbus A350 or Boeing 787.
The LEAP TAPS II combustor reduces NOx emissions by 50% compared to current CFM 56 engines with identical overall pressure ratio.
The unique LEAP debris rejection system helps prevent sand, dirt, and other harmful items from reaching the core. As a result, the LEAP engine stays newer, longer.
