New A320 With Winglets... Big Save?

Wed Apr 05, 2006 2:29 am

Now that Airbus is planning on putting winglets on the A320 will it make much of a diffrence? And what airlines are likely to put them on there A32X fleet?

Here in the states, I can see JetBlue adding them to some of or perhaps all of their fleet. It would definately help on the transcons out of JFK and back.

Those are way too fugly, I tell ya! Make it look like a Russian Bloc made airliner. The 737NG winglets are more sexier. If Airbus was to redesign the wingtip fences, do something that's more attractive and bring life to the aircraft while keeping efficency in mind.

You would say that, though, wouldn't you?  Smile For once, I agree with you. However, I was under the impression that they were going to put blended ones on it?

They look fine to me. They aren't blended like the 737s but that just makes it cheaper to produce and easier to install. The sharp edge creates a larger drag penalty. But I'm sure the studies were done and the straight edge was found to be the most economical when all costs were considered. We can see how much of a difference it makes by keeping an eye on how many airlines opt for the winglets. I personally don't think it'll make too much of a difference otherwise Airbus would've had the option years ago. Just my

Actually, the winglets on this plane are there because of a special request from JetBlue. They also asked Aviation Partners for a proposal, so it's time to look forward to their plane too. There was a picture a while ago, but this turned out to be a fake one. ( http://rockymountainavphotos.com/Eric/basic_images/B6AVPwinglets.jpg , just search for the reg on a.net and you see the same picture without the winglets ).

It's a balance between manufacturing and installation costs on the one side and fuel savings on the other side. With fuel prices as high as they are now, the balance gives a different outcome than two years ago. So, it's not strange that they come with the option only now. You also see the mass orders for 737NG winglets only since a year or 2.

Airlines have been requesting Airbus for years to improve the winglets on the aircraft.

Even if you improve the efficency between 1% - 2%, that is a major savings to the airlines, & will help airlines like Jetblue to fly from the west coast to the east coast without taking a tech stop....

From a looks point of view - I hope they don't put the blended ones on. I always thought the ones on the 737s were atrocious. Too in-your-face - like a big SUV.
But hey, it's all a matter of opinion when it comes to looks. Maybe if I get drunk the blended ones will look nicer  drunk   biggrin

I wasn't aware JetBlue requested these, thanks for the info.  Smile Good point, its only in the past few years that the winglets have become much more popular, most likely directly related to rising fuel costs.

You're exactly right. Winglets on the 320 line have never been an issue or particularly important to the airlines. Other Airbus aircraft have more conventional winglets and they work just as advertised.

For the short-haul missions that the 320 was designed for, the winglet weight penalty tends to outweigh any drag count benefit that the winglets provide. Recall too that adding winglets usually increases the wing root bending moment, so it's not a simple case of just attaching them and off you go. Depending on the winglet geometry, structural changes may be necessary. So that's added cost for a doubtful benefit for the normal 320 mission profile.

There also isn't too much between winglet performance in terms of design, they are usually within a few fractions of a percent of each other when structural variations are taken into account. So, the wing-tip fences normally seen on the 320 actually perform comparably with winglets whether they are blended or conventional (ie, aviation partners or winglet technologies design).

JetBlue are unusual in that they use the 320 on longer range missions, so minor improvements might possibly let them fly coast to coast, although I gather that this hasn't been proven yet. Nevertheless, JetBlue are keen to see if any fuel-burn advantage can be eked out of the 320 design on "longer" haul.

I think the winglets look kinda cute.

In design it is always better to avoid edges and pointy things. Smooth curves work a lot better.

This looks very good on the A320 in my opinion! There is something modern about winglets. I don't really mind whether they are blended or not. The A330 for instance looks fabulous with its winglets.

I'm glad to see the A320 with winglets. it is such a cool looking plane and now even cooler  Smile

Well done Airbus.

I agree the 73X's winglets are far more attractive to look at. Even my girlfreind, who doesn't know the first thing about airplanes saw a 73X on tv the other night and said she liked the winglets. The A320 ones look ugly. Sorry.

My guess is they don't make much of a difference, Airbus picked the little (and far more attractive) winglets they originally put there for a reason. i don't think many airlines will pick up on this option.

And the A330/340 winglets are far more attractive than these.

Jetblue uses the A320, on the US coast-to-coast market, West to the East. This is not exactly a short range flight, but would be classified as a medium range flight, which is what the A320 is made for...... If the A320 was not made for these flights, Jetblue would have never purchased the aircraft.

to me those winglets look like the ones similar to the 744, but they just dont sit well to the eyes. they've had time to see the ones on the 737 series and on the 75. Couldn't they have come up with a better design? oh well if it gets what they say it will do then who are we to complain, all that matters is the airlines bottom line.

I see how they just may not look right. . . . . .Now. But then, even the blended winglets the 73Gs have looked a bit out of place at first.

I think in both of these cases, it's like coming home for x-mass and noticing your mother's breast job. Looks a bit wierd, out of place, etc... at first, but you get used to it sooner or later.

Well, this is still the Airbus testbed. It's the first A320 ever produced and the one that is used for all testing. AFAIK, they will first do several tests with this one to improve the design, find flaws, etc. Later, a JetBlue jet will arrive and will get the winglets installed, and will actually fly revenue flights with it, to test the winglets in daily operations.

Well, MidnightMike is right at the point that not too many operators use the A320 on that long flights, so there are not too many operators that can benefit from the full improvement potentiel. When you look at the European market with many large operators (BA, LH, AF, AZ, IB) they hardly use them on routes over 2 hours.

As for JetBlue, they, or Airbus, might have indeed been a bit too optimistic about the A320's range. Well, it this is the solution, so be it.

Unfortunaly not a very accurate article:
The first devices are large winglets resembling those fitted onto various Boeing types including the 737 Next Generation-based Boeing Business Jet 2.

They look more like A330/340 winglets to me. Perhaps a new editor.

There is a very interesting last paragraph in the article:

A second design will be tested on an aircraft provided by JetBlue. The devices have been designed by Wichita, Kansas-based Winglet Technologies and is believed to be an elliptical winglet shape, similar to one developed for flight tests on a Bombardier Challenger 600.

I googled in the company but I couldn't find a webpage. This is an interesting article though ( http://www.bizjournals.com/wichita/stories/2002/03/04/story3.html ) but I want to have a picture of the Challenger with the elliptical winglet  Smile

I personally think that they look terrible, the current wingtip fences look much better IMO.

Quoting Joost (Reply 10):
They also asked Aviation Partners for a proposal

I really hope that the Aviation Partners option offered for consideration will look a lot better.

I think in both of these cases, it's like coming home for x-mass and noticing your mother's breast job. Looks a bit wierd, out of place, etc... at first, but you get used to it sooner or later.

Well, to be truthful, the first time I saw a 737 with winglets (a WN plane) I thought it looked more natural (And nicer) than it looked without them. I'll never have to worry about the boobjob situation, though.

The picture Keesje posted looks interesting, but from that angle it reminds me of someone flipping me off.

I think they look awful. To be fair, I don't like the 737 winglets, either. I guess I just far prefer raked wingtips to other devices.

Search around, there was a thread a while back where somebody(AeroWeanie?) posted a picture of a wind tunnel model.

Not me - I have yet to see a picture of the Winglet Technologies winglets.

Quoting Hb88 (Reply 15):
There also isn't too much between winglet performance in terms of design, they are usually within a few fractions of a percent of each other when structural variations are taken into account. So, the wing-tip fences normally seen on the 320 actually perform comparably with winglets whether they are blended or conventional (ie, aviation partners or winglet technologies design).

Not so. To quote myself in How Do Winglets Differ From Each Other?:

This thread covered this topic back in March:
What Difference Does Each Type Of Winglet Make? (by RootsAir Mar 18 2005 in Tech Ops)

To reiterate my summary:

For a first-order analysis of the benefit from a winglet, lay it down flat as if it was a span extension. Hence, taller is better. Then, look at whether the winglet joins the wing in a sharp break or a smooth flow. Smooth is better.

Using this criteria, I'll rank the winglets (and raked tip):

1) The A3100/310/318/319/320/321/380 "winglets" are the least effective, but also increase wing bending moments the least. I have never seen a published number for how much they reduce drag (even Jupp's patent US4,714,215 says little), but I'd guess they are worth 1-1.5% drag improvement.

2) The MD-11 winglets come next. They are a direct outgrowth of Whitcomb's original designs. I have some NASA reports on the flight testing of a similar winglet on a DC-10. According to CR-3704, these winglets are produce a 2-2.5% drag reduction in cruise.

3) The Valsan/Quietwing 727 winglets are a latter Whitcomb influenced design. Coupled with a flap droop on the 727, they are reputed to be worth about 5%. The flap droop reduces wing bending moments and helps reduce wave drag, so the 5% is a mixture of effects. The winglet by itself is probably worth about 3%.

4) The 747-400 and A330/340 winglets are rather similar. They fall on the wing span extension line. I've read that the 747-400 winglets produce about a 3.5% drag reduction.

5) The 776-400ER/777-300ER/777-200LR raked tips also fall on the span extension line. They produce varying amounts of drag reduction, depending on their span. They also increase wing bending moments quite a bit.

6) The API/APB blended winglets produce better results than the span extension line indicates. The 737NG winglets are first generation and I've read that they produce about a 4.5% drag reduction. Later API/APB winglets improve on this.

I don't like the ones on the 737, because I think they are too big! the 737 looks way better without. Luckily the winglets are not designed to satisfy a.netters but to save fuel, so that we can get our flight tickets cheaper.

First, very nice summary. Note: there is a techops discussion also on this topic. I bow to your superious knowlege of wing design. I love it when I learn something on a.net.  Smile

These are the numbers people like to quote for winglet improvements. Do recall, this is with the benifit of the latest generation CFD and don't forget that these are at least a 3rd generation design and thus benifit from decades of aquired learning.  Smile

And why all of the discusion on winglet looks? They are there for one purpose: to improve the economics of the airframe.

Although, if B6 is the launch customer, why are the winglets being tested with CFM-56 engines and not V2527's? Ok, I realize the engine selection will not impact winglet performance. But I have my biases.  Wink This is an A320 with V2500's:

Just out of interest - is that Jeff Jupp? As I couldn't find anything abotu that patent. The only thing I can find in Google is this thread Big grin

There was a frontal view in the Flight Magazine a few weeks ago. Here's the text, but no pics unfortunately.
