New
technology to give MAX customers up to additional 1.5 percent fuel-burn
reduction
RENTON,
Wash., May 2, 2012 /PRNewswire/ -- Boeing (NYSE: BA) announced today a new
winglet design concept for the 737 MAX. The new Advanced Technology winglet
will provide MAX customers with up to an additional 1.5 percent fuel-burn improvement,
depending on range, on top of the 10-12 percent improvement already offered
on the new-engine variant.
"The Advanced
Technology winglet demonstrates Boeing's continued drive to improve fuel burn
and the corresponding value to the customer. With this technology and others
being built into the MAX, we will extend our leadership," said Jim
Albaugh, president and CEO, Boeing Commercial Airplanes. "Incorporating
this advanced technology into the 737 MAX design will give our customers even
more advantage in today's volatile fuel price environment."
Compared
to today's wingtip technology, which provides up to a 4 percent fuel-burn
advantage at long ranges, the Advanced Technology winglet provides a total
fuel-burn improvement of up to 5.5 percent on the same long routes.
"The
concept is more efficient than any other wingtip device in the single-aisle
market because the effective wing span increase is uniquely balanced between
the upper and lower parts of the winglet," said Michael Teal, chief
project engineer, 737 MAX.
Boeing
aerodynamicists used advanced computational fluid dynamics to combine rake
tip technology with a dual feather winglet concept into one advanced
treatment for the wings of the 737 MAX. The Advanced Technology winglet fits
within today's airport gate constraints while providing more effective span
thereby reducing drag. Ongoing 737 MAX testing in the wind tunnel validated
the new concept on the airplane.
The
super-efficient design has been incorporated into the 737 MAX design and
production system plans. "We have assessed the risk and understand how
to leverage this new technology on the MAX within our current schedule,"
said Teal. "This puts us on track to deliver substantial additional fuel
savings to our customers in 2017." Airlines operating the 737 MAX now
will gain an 18 percent fuel-burn per-seat improvement over today's A320. Depending
on the range of the mission, MAX operators will realize even more savings.
"Adding
the Advanced Technology winglet to the 737 MAX is consistent with our
demonstrated performance on delivering increasing value to our customers, on
time, throughout the life of the 737 program," said Beverly Wyse, vice
president and general manger, 737 program.
To date,
the 737 MAX has more than 1,000 orders .
