Aviation Partners Boeing (APB) has announced that Icelandair is the first airline in Europe to install and operate with scimitar blended winglets (SBW) on its Boeing 757-200 aircraft, the company said.
The SBW uses existing blended winglet technology, but adds new aerodynamic scimitar tips and a small outboard aerodynamic trailing edge wedge, further increasing the efficiency of the airplane. The SBW modification reduces Boeing 757-200 fuel burn by up to an additional 1.1% over the blended winglets alone; together they can reduce fuel burn by more than 6%.
A retrofit enhancement to their current 757-200 blended winglets, Icelandair expects increased savings to block fuel, reduced engine maintenance, improved takeoff performance, and lower emissions, among other benefits.
The SBW replaces the standard aluminum blended winglet tip with an aerodynamically optimized, scimitar-shaped tip cap. This helps provide the additional drag benefit over the standard blended winglet configuration.
Icelandair is currently working on their 4th SBW modification and plan to have a total of 17 units in service before the 2017 summer season.
