Types of Blended Winglets

Our variety of winglets, from Blended, to Split Scimitar™ and Spiroid, all share one characteristic: They’re the most effective in the industry.

Aviation partners Blended Winglets

Blended Winglets

The Blended Winglet has a large radius and is designed with a smooth chord variation in the transition area where the wing joins the winglet. This allows optimum aerodynamic loading and avoids vortex concentrations that produce drag. Aviation Partners’ Blended Winglets have demonstrated more than 60% greater effectiveness over similar sized winglets with angular transitions.

Split Scimitar Winglets

The Split Scimitar Winglet redefines the aerodynamics of the existing Blended Winglet on the Boeing 737NG family. The combined aerodynamic elements of the retrofit — ventral strakes, scimitar tips, and trailing edge wedges — provide a drag reduction, and corresponding range increase, of 2 percent or more for long-range missions. These winglets are now standard on all new Boeing Business Jet aircraft, and are already in service on over 700 Boeing 737NG airliners.

Aviation partners Spiroids

Spiroids

We are constantly developing new ways to improve the aerodynamic efficiency of future aircraft. Our Spiroid Winglets, which look like a loop of rigid ribbon at each wing tip, were originally tested on the Gulfstream II in 1993; and refined for further proof-of-concept testing on Falcon 50 in 2010. We are currently studying possible future applications for Spiroid Winglet technology on a number of business and commercial aircraft types.

  • "Blended Winglets are the single most significant aerodynamic improvement ever developed for commercial or business aviation."

    Clay Lacy, Aviation Founder & CEO
  • "At M.80 [and FL450] the fuel flow was 1,700 lbs/hr, which would compare with almost 2,000 lbs/hr down at 410 without the winglets. Clearly, the combination of improved wing performance and improved fuel specifics at the higher altitude is a great combination for range."

    Randy Greene, Chairman/Pilot, Safe Flight Instrument Corp., Falcon 900B
  • "We are thrilled with the installation of our winglets. The performance we are achieving is well beyond my expectations."
