Aviation Partners Boeing has formally received an order from TUI Travel for 737-800 Split Scimitar Winglets. This program is the culmination of a five year design effort using the latest computational fluid dynamic technology to redefine the aerodynamics of the Blended Winglet into an all new Split Scimitar Winglet. The unique feature of the Split Scimitar Winglet is that it uses the existing Blended Winglet structure, but adds new strengthened spars, aerodynamic scimitar tips, and a large ventral fin. This advanced technology winglet is the ultimate winglet in terms of performance, without increasing the existing wing span. Earlier this year, APB launched the Split Scimitar Winglet program for the provisioned wing 737-800 (line number 778 and on) and 737-900ER with an order from United Airlines. FAA supplemental type certification for the Boeing 737-800 is targeted for October 2013 and EASA certification planned for December 2013. Certification flight testing of Split Scimitar Winglets is currently underway.
