Snecma
More efficient aircraft engines
Your challenge
The LEAP turbofan engine is a new-generation aircraft engine designed and developed by Snecma and GE under an ambitious technological development program. The Snecma engine will replace the CFM56 Tech engine currently equipping the Airbus A320 and the Boeing 737 and be used to power next-generation short- to medium-range narrow-body aircraft. The new engine has already been selected by Chinese aircraft manufacturer COMAC for the planned C919 and by Airbus for the A320neo. To meet the environmental standards set by the International Civil Aviation Organization, the LEAP will reduce fuel burn by 15%, nitrogen oxide (NOx) emissions by 50% and noise levels by 15 EPNdB (effective perceived noise in decibels). These objectives are being achieved through making engine components lighter and introducing new materials. Every ounce counts. The fan blades, usually made of metal, will be replaced by composite blades to lightweight the engine. The composite can support the extremely high temperatures found in the turbine, but does not offer the same mechanical strength.
