Leap is a new-generation engine designed and developed by CFM International, the 50/50 joint company of Snecma (Safran group) and General Electric, through a very technologically ambitious development program.
The new Leap engine will incorporate a number of innovative technologies developed through the Leap™ research & technology program. It is mainly designed to power the next generation of single-aisle commercial jets.
Leap features a host of advanced technologies to help reduce its fuel consumption by 15%, NOx emissions by 50% and noise to 15 EPNdB (effective perceived noise in decibels). For example, there will be fewer fan blades and they will be lighter, since they are made of composite materials using a proprietary woven 3D RTM (resin transfer molding) process. The use of these new composites on fan blades and other components would reduce the weight of each aircraft by up to 1,000 pounds.
