This KC-767 winglet is whack

Boeing has revealed an all-new and unusually curved winglet on the KC-767 model prominently displayed in its exhibit booth at the AFA convention.

But don’t get excited.

The new winglet design is not accurate and is possibly just a model-shop mistake, Boeing officials insist.

Although Boeing declined to reveal the true shape of the KC-767 tanker winglets, the company’s other official marketing materials have not deviated from the more conventional, straight winglets already certified on commercial airliners.

The new model for the AFA booth arrived with the symmetrically misshaped winglets, and Boeing officials had not confirmed whether it was a glitch in packaging or construction.

    Was the “mistake” the exact same on both wings?

    You’re actually looking at both winglets, although from different angles. They appeared to me to be identical.

    that may be a solution

    to the kc767i problem

    on the refueling drogues

    it seems there will be more kc767 flying

    than kc330′s

    look at bedek and other conversions

    I think the guys behind this stunt are wetting their pants over your bewilderment and speculation.

    Well of course they were identical, the model was centered into the crate before they pushed it down and created this new concept in winglets.

    Richard whitcomb would be proud.

    If Boeing was smart they would have said; “Oh yes using the latest proprietary Boeing CFD program we have developed these new winglets that reduce fuel burn by (insert outlandish number here) % and increased range by (insert outlandish number here)%

    They could have forced EADs and US Aerospace into countless wasted hours of wind tunnel research.

    If it were an accident that happened while shipping, wouldn’t the tail also be squished?

    I wonder if the model shop mistake was shipping a model with a new winglet design that Boeing didn’t want the competition to see yet? The winglet doesn’t look implausible. A guy I knew in university did his Ph.D. on winglet design, and his conclusion was that there wasn’t a clear upper size limit in terms of the aerodynamic benefits of a bigger winglet. The trick was balancing the structural penalty with the anticipated benefit in reduced induced drag. The 787 shows something similar – no distinct winglet, instead a gradual upwards curvature in the wings towards the tip.

    Stephen didn’t take a picture of the Boeings new and innovate “L” tail.

    Formula 1 winglet design goes flying.
