Powering Test Equipment for Winglet Development

ETI worked with Aviation Partners in conjunction with Boeing to power sensative test equipment. This equipement was used aboard aircraft for prototype monitoring to help with the development of winglets for use on Boeing's 747 aircraft.

APB's Split Scimitar Winglet retrofit program consists of retrofitting 737NG's winglets by replacing the aluminum winglet tip cap with a new aerodynamically shaped "Scimitar" winglet tip cap and by adding a new Scimitar tipped ventral strake. This modification demonstrated approximately 2% drag reduction over the basic Blended Winglet configuration.[8] FAA granted supplemental type certification (STC) for the Split Scimitar Winglet (SSW) retrofit on the 737-800 and BBJ2 on February 6, 2014, for 737-900ER on August 27th, 2014, for 3 additional 737-800 wing configuration on October 2, 2014, and for all models of the 737-700 including the Boeing Business Jet on April 21, 2015.[9] APB expects Scimitar Winglet Systems installed on a 737-800 to save the typical airline more than 45,000 gallons 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 pounds or increase its range up to 75 nautical miles.
