Jet Engine LEAP®
Welcome to the great LEAP® forward: the next-generation engine developed by Snecma and GE, via their jointly-owned company CFM, offers a perfect combination of performance and technology. Developing 28,000 to 34,000 pounds of thrust, the LEAP delivers major efficiency benefits for operators of the next generation of single-aisle commercial jets, including a 15% reduction in fuel consumption and CO2 emissions versus current engines, a 50% cut in NOx emissions, and compliance with the most stringent noise standards (the ICAO's Chapter 14 regulations). These performance benefits are built on the proven technological excellence of Snecma and GE. For example, Snecma developed a new 3D woven composite material for the fan case and blades. Other innovations from Snecma include the advanced 3D aerodynamic design technique used for the blades of the low-pressure section, and new stronger, lighter alloys such as titanium aluminide (TiAl) and ML340. The LEAP design draws on the very best aspects of the CFM56, including exceptional reliability and unrivaled operating costs, as well as low maintenance costs thanks to optimized engine architecture, making the LEAP the engine of choice for next-generation single-aisle jetliners. The three available versions have already been selected by the world's leading planemakers: the LEAP-1A® to power the Airbus A320neo; the LEAP-1B® for the Boeing 737 MAX; and the LEAP-1C® for the COMAC C919. With entry into service scheduled for 2016, the LEAP is already the best-selling engine under development in history, with more than 9,550 orders and commitments as of June 18, 2015. Adapting to the sustained production rates demanded by planemakers will represent an unprecedented challenge for Snecma and CFM. Safran has therefore invested in new industrial capacity, notably by building two new dedicated facilities for the production of 3D RTM composite parts. Snecma is also able to draw on the unique expertise of its teams as well as the suppliers in its international supply chain, and has established high-added-value partnerships with key small and intermediate-sized companies.
