Did you know that something as simple as the tip of an aircraft’s wing can dramatically change its efficiency? Boeing does.
Boeing has developed 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% fuel-burn improvement, depending on range, on top of the 10-12% improvement already offered on the new-engine variant.
Compared to today’s wingtip technology, which provides up to a 4% fuel-burn advantage at long ranges, the Advanced Technology winglet provides a total fuel-burn improvement of up to 5.5% 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. —Michael Teal, chief project engineer, 737 MAX
