Blended Winglet technology saves jet fuel

Aviation Partners®, Inc. (API), in conjunction with Aviation Partners Boeing (APB), API´s joint venture with The Boeing company, Blended Wingletâ„¢ Technology has saved the world´s commercial and business jet operators an estimated six billion gallons of jet fuel, the company said.

The savings represents a global reduction in CO2 emissions of over 64 million tons, equivalent to the fuel used by approximately 12 million passenger cars being driven for a year (or every car in Seattle, home to API and APB, for approximately 25 years) and enough CO2 to cover 1.1 million square kilometers (approximately the combined land area of Texas and California) to a depth of one meter.

Aviation Partners´ designed Blended Winglets are now flying on more than 7,000 individual jet airplanes and over 20 airplane types.

Blended Winglets are additions to the airplane wing increase efficiency. The Winglets reduce the drag caused by wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplane´s wing and that on the lower surface. By reducing drag Blended Winglets increase fuel efficiency and boost range.

The Blended Winglets, which feature a large radius and smooth chord variation in the wing-to-winglet transition area, have demonstrated more than 60 percent greater effectiveness over conventional winglets with an angular transition. Aviation Partners´ latest Winglet design, the Split Scimitar® Winglet, uses existing Blended Winglet technology but adds new aerodynamic Scimitar tips and a large ventral strake, further increasing the efficiency of the airplane. This new design is already flying on almost 700 Boeing 737 Next-Generation airliners and business jets.

Seattle, Washington based Aviation Partners, Inc. (API) is the world leader in advanced winglet technology. Aviation Partners Boeing (APB) is a joint venture between API and The Boeing company.
