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 became standard on the final 737 NG Boeing Business Jets, and are now flying on approximately 1,700 737 NG airliners.

Aviation Partners has transformed aviation for more than 25 years with our performance-driven, fuel-saving advanced winglet technology.

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.

  • "We see API winglet-equipped aircraft trading several percent higher and spending less time on the market. We know that our clients will enjoy the performance advantages of those winglets during the ownership lifecycle – but they always seem to enjoy the resale value even more."

    Jim Lewis, Sr. Managing Director, MENTE Group, LLC
  • "As a full-time contract pilot, I fly the whole range of Hawker 800s and 900s. When I'm with a client who has API winglets, I absolutely notice the positive difference in fuel burn and climb performance versus non-winglet airplanes."

    Josh Hunter, Queen City Flying Service
  • "So happy to have our airplane fitted with the most amazing winglets… it made a big difference on the performance."

    Claudio Varo, Chief Pilot, Wallan Aviation, Falcon 900EX EASy
  • "It looks amazing, flies like a dream, but it even outperforms the 900XP in second segment climb and better cruise speed at altitude. Honestly, there should be API winglets on all wings in the world."

    Kristoffer Sundberg, Founder & CEO, JoinJet A/S & SmuuthCare A/S, Hawker 800XP
  • "The winglets have just transformed the airplane. It flies better. It’s changed the profile of how we can operate the airplane. From Seattle, we can go direct to Europe."

    Bruce McCaw, Owner/Pilot, Falcon 900EX
  • "We are thrilled with the installation of our winglets. The performance we are achieving is well beyond my expectations."

    Brian Katz, Aviation Manager/Chief Pilot, The Dawson Companies, Hawker 800XP
  • "Blended Winglets are the single most significant aerodynamic improvement ever developed for commercial or business aviation."
