Split scimitar winglets

[underfire]

No idea there were so many split scimitar winglets in operations...

Any drivers have comments on the differences, etc?

[ACMS]

Holy smokes, something you didn't know.

Who would have guessed....:ok:


I guess your surface movement radar didn't pick that one up:}

The nature of winglets being what they are, a pilot is not going to feel the difference. The bean counters paying for fuel would see the difference.

[megan]

a pilot is not going to feel the differenceMaybe not, but they do influence limitations, eg crosswind.

[Airmann]

Looking at hte scimitar I noticed that the upper winglet actually looks to be the standard 737 winglet while the downward facing one appears to be more or less added on. On installing the scimitar, do they need to remove the entire winglet and add on an entirely new one or simply add on the bottom winglet to the existing winglet?

[FlightDetent]

The upper one looks differently, seems to be a completely new kit.

This pilot does.

The current APB split scimitar is a modified blended winglet.
When you receive a scimitar winglet you return your old blended winglet which will then get reworked and sold to another customer. This is also reflected in the list price the scimitar upgrade only cost half of what an initial blended winglet installation does.

The new 737MAX is using a completely different type


I was also surprised to see how many airlines in the USA using them, the only airline I can recall seeing in Europe with them is TUI.

[Amadis of Gaul]

The look very scimitarly.

[underfire]

Chesty..can you provide some detail?

ACMS, I would expect no less from you.

[Mr.Falcon]

I do feel a difference in the flare between no winglets vs blended winglets. An aircraft without winglets sits down nicely, while an aircraft with winglets needs less flare and tends to float a little longer.

Haven't flown yet with the Split scimitar winglets.

[misd-agin]

Winglets make the plane feel 'slick' during the descent and on landing.
Airliners were given speed brakes back in the 1960's in anticipation of the slickness of winglets.

Split scimitar winglets are new kit. The wing has an additional stringer added via the fuel tank access points. There are some new counterweights added. The ailerons are given droop of a few degrees. Not all NGs can accept the scimitar.

[tdracer]

Not all NGs can accept the scimitar.
Not all NGs can accept winglets - at least not without significant structural modification.
IIRC, the -800 and -900 could accept winglets without structural mod, but the early build -700 needed major structural mods to accept winglets (naturally later build -700s had that added during build.)

[nomorecatering]

So which one is the best, most efficient. The design on the Max or the other split schimitar retrofit design. The 2nd certainly looks the best.

[Jonno_aus]

But I don't see any scimitar winglets on Boeing aircraft in that YouTube clip. :confused:

Cool vid though. Madeira airport if I'm not mistaken.

[Out Of Trim]

Jonno_aus,

Better book the eye test then! :8

The 2nd & 3rd A/C in the video definitely had them.. :cool:


>---o--0--o---<

[Jonno_aus]

Oh yeah. So they do. :8

Serve me right for fast forwarded to the interesting part...the landing.

Or is that 'landing'? :}

TUI flies short hops, actually, the split scimitar/winglet is a detriment...(ie the weight/constraints/benefit)

United flies them, just not certain how many ac have been retrofit with them, and/or to any benefit.

The vast majority uf UA 737's have them, I only very rarely see a normal winglet nowadays. Apparently they were also looking into getting split scimitars for their 757's and 767-300, but the press release regarding those mods was slightly ambiguous.

Interestingly they haven't bothered with winglets on their A32X, but who knows how long those are still going to be around for.

Other US airlines seem to have a mix: WN, AS and DL all seem to have a jumble of winglets and split-scimitars, not sure which variant is dominant.

[underfire]

thanks trip,
down under, Tiger was supposed to be getting sharklets, but I have only seen one on the Adelaide-SYD run. Virgin has a sharklet 320, but only one I know of.
I have seen no split scimitar down under.

Puzzled ...

yesterday I posted a history of winglets and two links- at teh end of the comments of the second link was a ' similar' story- It was similar since I had forgotten that I had posted that comment - under my name- in 2014- in response to a not well received article which had lots of opinion- biased and little facts. Not too surprising that it was essentiually the same. I did not discover that until several hours AFTER I had posted- and had decided to read ALL the comments for the link.

So in my post yesterday - I added some comments which said truthfully I had not copied or paraphrased that comment without attrtibution- and ended with a smiley http://cdn.pprune.org/images/smilies/smile.gif - I thought/assumed that anyone reading would understand I had told the same factual story/comment in the same way simply cuz I was the same person.

Apparently the moderators did not agree... sad...http://cdn.pprune.org/images/smilies/sowee.gif
