FACC AG (Ried im Innkreis, Austria) reported on April 4 that it has received an order from Aviation Partners Boeing (APB, Seattle, Wash., USA) to produce the new Split Scimitar Winglet. The newly developed winglet design is based on the existing Blended Winglet, likewise manufactured by FACC, and is being offered by APB as a retrofit for Boeing 737 Next Generation (737NG) aircraft. FACC says that with innovations like an aerodynamically shaped Scimitar winglet tip cap as well as an additionally Scimitar tipped Ventral Strake, fuel can be saved and range and payload can be increased.
APB is a joint venture between Aviation Partners Inc. and Boeing and is responsible for the development and marketing of blended winglets for Boeing aircraft. In the framework of the project, FACC performs the development, construction, stress analysis, modification and manufacturing of the Split Scimitar Winglet as well as the development and procurement of production tools. The contract, valued at three-figure million euros, foresees shipments for more than 3,000 aircraft over the next five years.
"Aviation Partners is well known for its powerful innovation in the development of fuel economic winglets. Thanks to the optimised aerodynamics the new split winglet design enables the airlines to have lower costs and a higher efficiency in aircraft operation," says Walter Stephan, FACC CEO. “We are very proud to be working again for APB in this hugely promising winglet programme as development and manufacturing partner. With this, we also look forward to making an important contribution towards a ‘greener’ flying with a significantly reduced environmental footprint."
The prototype of the Split Scimitar Winglet successfully completed an in-depht flight test program, the evaluation of which showed a significant reduction in aerodynamic drag compared to conventional Blended Winglet technology. APB and FACC expect Scimitar Winglets Systems installed on a provisioned 737-800 to save the typical airline more than 45,000 gal/170,343 liters of jet fuel per aircraft per year resulting in a corresponding reduction of carbon dioxide emissions of 476 tons per aircraft per year. The fuel savings can enable a 737-800 to increase its payload up to 2,500 lb/1,134 kg or increase its range up to 75 nautical miles.
