A technological LEAP forward

The LEAP® engine was developed by Safran Aircraft Engines and GE through their joint company, CFM International, to power the next generation of single-aisle commercial jets. Combining the best technologies from the two partners, LEAP offers operators exceptional performance while retaining the legendary reliability of the CFM56®. These capabilities have already made the engine a best seller, even before it has entered revenue service.

The LEAP® engine is designed, developed, produced and marketed by Safran Aircraft Engines and GE through CFM International. Three different LEAP® versions have already been selected to power the new generation of single-aisle commercial jets from the world's leading manufacturers: LEAP-1A for the Airbus A320neo, LEAP-1B for the Boeing 737 MAX, and LEAP-1C for the Comac C919. This advanced turbofan incorporates the best technologies and materials from its two parent companies, such as 4th generation 3D aero design, 3D woven composites using the RTM (resin transfer molding) process, and titanium aluminide. The result is a significant decrease in fuel consumption, CO2 emissions and noise, while maintaining the industry standard reliability of CFM engines. CFM International has already recorded over 17,400 orders and commitments for the three versions of the LEAP®.
