Performance, Drag Improvements Provided At No Additional
Cost
The first Boeing Next-Generation 737 with the certified
performance improvement engines was delivered on a 737-800 to China
Southern Airlines at Boeing Field in Seattle 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 savings.
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 percent. 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 customers."
Boeing says that its efforts to improve the Next-Generation 737
family have resulted in an accumulated 5 percent gain in fuel
efficiency since the first airplane delivered in 1998. The new
improvements will give operators an airplane that is up to 7
percent more efficient than the first Next-Generation 737s
delivered.
