"We look forward to continuing to build a strong
relationship with ALC and are excited to bring
all the benefit of LEAP technology to their
customers," said Kevin McAllister, vice
president of Global Sales for CFM parent company
The LEAP-1B, which is the result of an
exhaustive six-year collaboration effort with
Boeing, is the exclusive powerplant for the new
737 variant, with the engine uniquely optimized
for the airplane. The 737 MAX continues a
30-year relationship between CFM and Boeing; CFM
engines have been the sole powerplant for all
737 aircraft sold since 1981.
LEAP engines incorporate revolutionary
technologies never before seen in the
single-aisle aircraft segment. The new engine
combines advanced aerodynamic design techniques,
lighter, more durable materials, and
leading-edge environmental technologies, making
it amajor breakthrough in engine technology.
As a result, operators of the 737 MAX will
achieve 10 â€“ 12 percent lower fuel burn
compared to today's best CFM56-powered 737; an
equivalent reduction in carbon emissions; a 50
percent reduction in NOx emissions versus
current ICAO CAEP/6 requirements; a 75 percent
reduction in the aircraft noise footprint; all
while maintaining the benefits of CFM's
legendary reliability and low maintenance costs.
engines are a product of CFM International a
50/50 joint company between Snecma (Safran
group) and GE.
