The first Boeing Next-Generation 737 with the
certified performance improvement engines was delivered on a
737-800 to China Southern Airlines last week.
The new CFM56-7BE engine configuration, which is
now standard on all delivered 737s, is an improved design that
includes high and low pressure turbine modification.
Coupled with drag reduction improvements that
Boeing started phasing into 737 production earlier this year, it
will result in lower fuel consumption and maintenance cost
The new engine is part of the 737 performance
improvement package that Boeing began testing in November 2010
with the goal of reducing fuel consumption by 2%.
Other fuel performance incorporations will take
place into 2012 and data analysis will continue to quantify the
final benefit to customers.
"We continue to review performance flight test
data and collect delivery data," said John Hamilton, vice
president and chief project engineer – 737 program, Boeing
Commercial Airplanes. "The improved fuel savings is part of our
commitment to deliver market-leading value to Next-Generation 737
Boeing's continuous efforts to improve the
Next-Generation 737 family have resulted in an accumulated 5% gain
in fuel efficiency since the first airplane delivered in 1998. The
new improvements will give operators an airplane that is up to 7%
more efficient than the first Next-Generation 737s delivered.
