The revolutionary LEAP fuel nozzle.
The LEAP engine is introducing the second generation Twin-Annular, Pre-Mixing Swirler Combustor (TAPS II). Arguably the industry's most advanced combustor, TAPS II is reducing NOx emissions by 50%*.
A technology critical to achieving those reductions is the advanced fuel nozzle. Unlike traditional combustors that mix fuel and air inside the combustion chamber, the LEAP nozzle pre-mixes these elements to provide what our engineers call lean burn combustion. We just call it revolutionary.
Even the way the part is manufactured is another CFM first. This very sophisticated nozzle is actually "grown" using additive manufacturing. It's just one more way CFM gives you more to believe in.
*Compared to current CFM 56 engines with identical overall pressure ratio.
