100 - 200kN turbofan LEAP-1C

300kg +for airlinersfor general aviation

Designed, produced and marketed by CFM International, the LEAP-1C is the only Western engine offered on the COMAC C919, a new-generation single-aisle jet from China. 15% reduction in fuel consumption and CO2 emissions* *Compared to previous-generation engines. Up to 50% reduction in NOx emissions* *In accordance with the ICAO’s CAEP/6 environmental standard. Meets the most stringent noise standards (the ICAO’s Chapter 14) An environmentally-friendly engine Designed to meet the challenge of decarbonizing air transport, the LEAP-1C engine offers COMAC C919 operators enhanced performance in terms of fuel consumption and CO2 emissions (15% lower1), NOx emissions (up to 50% lower2) and noise (in accordance with Chapter 14). 1. Compared to previous-generation engines. 2. In accordance with the ICAO’s CAEP/6 environmental standard. Innovation from nose to tail To achieve its remarkable performance, the LEAP-1C is packed with innovative technologies and materials. The use of a 3D woven composite material and the RTM (resin transfer molding) process developed and patented by Safran Aircraft Engines makes it possible to produce fan blades that are lighter, stronger and more durable. The low-pressure turbine blades are machined from an innovative titanium-aluminide alloy that is lighter and more resistant to high temperatures. The low-pressure turbine rings and airfoils are made of CMC (ceramic matrix composite) materials and the fuel injectors are 3D printed. High-performance industrial organization Thanks to Factory 4.0 facilities and unique processes, Safran Aircraft Engines has achieved a production ramp-up that is unprecedented in commercial aviation history.
