To save fuel United Airlines is adding additional winglets to the wingtips of their airplanes.
To save fuel United Airlines is adding additional winglets to the wingtips of their airplanes.
The radical re-sculpting of traditional winglets adds a new tip below the upturned one that sharply curve backwards like a scimitar. That further reduces wingtip vortices that drag on the wingtips. Each traditional pair of winglets on the 737 cuts fuel consumption by 3.5% to 4% on flights of more than 1,000 nautical miles. The split scimitar upgrade—which costs $545,000, before discounts–will reduce fuel burn by up to 2% more, says United, which hopes to save up to $60 million a year because of the devices, once its fleet is outfitted.
Very smart. Expect to see these winglets appear on all commercial jets in short order.
