It's behind the Korean B739, looks like a normal B737 winglet with a strake beneath. Is it markedly taller than the current version? I didn't get that impression, mind you it was at ground level so could be wrong.

It also appears more of a 'sharklet'-type look as opposed to a 'winglet'....similar to what you might see on some Airbus a/c but on steriods.

More so an evolution of the MD-11 winglet IMO. The "sharklet" marketing name is just annoying. Its a winglet. :-P

There's one thing that's been bugging me about this new winglet, and I hope that somebody can shed some light on this.
With the lower section of the winglet extended so far down, what happens if a situation like this develops:
That's obviously a very extreme case, but with the winglet extended considerably downward, it wouldn't take as dramatic an angle for the wing to contact the ground.
Is the lower section of the winglet designed to break away?

Not really. The MD-11 winglet has a very small lower "feather", which is little more than a VG to control flow at the tip. The MAX lower feather is an actual lifting airfoil intended to increase the effective span of the wing. It makes a significant improvement to the L/D of the wing, which is where the added performance and efficiency is gained.

I would worry more about careless driving on the ramp. I think that's why the lower part of the MD-11 winglet has the red edge.

It is indeed NOT pronounced as the latter, I was in the show yesterday and Monday and I heard all the Americans finish the word with the 'O' sound as opposed to the 'Ugh', which is incorrect. It's a name, not a word!
I'm from Farnborough so I get quite defensive! :P
Saw the winglet too, and I'm not keen, not aesthetically pleasing at all, but then making aeroplanes look pretty is not the primary goal of the manufacturers.

I agree, it's not good looking at all. I like the shape of the top part, but the bottom part looks like the blades the Ancient Spartans had on the wheels of their chariots in battle.

yah, not even close. Most are missing that this is an extremely "3D" device instead of simply a couple new airfoil sections stuck on the end of the wing. Be really interesting to know exactly how critical the shape of that merge between the upper and lower sections are as its seems quite agressively shaped. Might be the result of the mere merge of the two sections or it might be the key to the who thing working much better than the current winglets.

Thanks for the clarification. I was thinking the lower feather was bigger than what it actually is. It's been a few years since I've seen one.

I love the shape of the new MAX winglet. Do you think Boeing or APB might offer it in this form or in a smaller version to modify NGs and/or classics?
If this new form is a real improvement in terms of efficiency, a smaller and lighter version, optimized for the NG wing could be developed in my opinion.

LOL! Yes, something which probably still chaps the hide of any former MD sales guys who surf these sites. I remember when we were designing the 777; internally, we were worried the MD-11 would be the real competitor for the 777 (not so much the A340). In the end, neither turned out to be competitive, but the MD-11 was in fact the least of our worries. Probably symptomatic of an overall misjudging of Airbus by Boeing that only really ended when we watched the A330 eclipse the 767. Safe to say, nobody is ignoring or underestimating Airbus today!

MD-11 .... been there, done that (decades ago).
Of course they don't look the same, manufacturing processes have changed since then. However the reason for putting on the lower winglet, on both aircraft, are/were exactly the same (to keep high pressure air from slipping around the wingtip to the low pressure topside).

For some reason I get the idea the upper portion is actually the same or even slightly smaller than the existing winglets. I could be wrong, and I have no technical data to prove or disprove it.
I know it's difficult to tell from the pictures alone, especially with different perspectives.

Interesting, because to me it almost looks tiny in that picture especially compared to the guy standing next to it. No way is that even close to the size of a 767 winglet. Have you seen a 767 winglet? its taller than the tail of a CRJ7 lol.

I disagree with this as well. The top portion to me anyway looks very different from the current 737/757/767 style winglet. Looks raked back more and seems to be much skinnier (and pointy towards the top.

The difference in appearance has nothing to do with manufacturing processes. Function drives form... the two devices have very different functions and therefore very different forms.

Not the case at all. The 737 lower feather is all about distributing lift over a greater span to reduce induced drag from the wing. It is a L/D feature, not a tip vortex control feature.

26 virgin747: If memory serves me correctly when that Lufthansa Airbus smacked its wing on the ground, the bottom portion of the wingtip fence just bent inwards.
