New winglets for A320

The first A320 is fitted with modified winglets by Airbus. It has made its first flight today. A picture can already be found on Airliners.net:

Looks quite weird, but not ugly.

Nice, they're bigger than the old ones.

They old ones had such a typical form...I liked them

The A321 will look even more like the TU-204!

Looks very nice indeed.

And what about performance? how will this affect the fuel consumption? Will it be possible for existing A320 to refit them with this new winglets?

Why do you think they are testing them?

are the winglets really that usefull, or it's also a trendy thing to have these days ?

Well I think it could be a trendy thing like you said Ovostar.

Why are they changing the winglets now?
The A320 already exists for such a long time....
And are they going to change all those A320's with "old" winglets"????

Boeing did the same with the B737 classic. The type of winglet on the A32X series is very old and I'm sure these type of winglets have their effect (otherwise B737Classic operators wouldn't order the 'blended winglets' type).

Let's see what the results of these test are

If you read closely you can understand that I was pointing on how MUCH MORE economic these NEW winglets will be. Or in other words what is the difference (% of economics) between these new and the older ones. I already know that winglets give you more economical operations on some flights.

Read carefully before you react.

Before testing these new winglets on this airbus 320, the engineers have artificially designed them and did some computersimulation tests on them. So the engineers already know (in theory) how better they are

Winglets increase efficiancy. Winglets prevent vortexes coming off the wingtips because they create drag. So winglets reduce the drag.

I think you misunderstood me. You are right about the second part, but you can never know how they will react in real.

Lol I wonder where you get this info? Winglets don't reduce the drag (why should they?), they give a better air flow which results in less fuel burn and lighter wake turbulence.

@Airbus_fan: look at this site:

I find that this winglets are not for a A320. I find that the winglets are to big for the A320. Can't they make them trendy like the one of the 737-7/8? Or like the small winglets on the 737-200 (like on the link above)?

fokker_f27 · Post by **fokker_f27** » 04 Apr 2006, 16:04

I like the classic airbus winglets too, but if these make the aircraft more fuel efficiant then the old winglets, then airbus is best off selling these.

You're completely right fokker_f27.

The do not prevent vortexes, they reduce them ! If they would truly prevent, then you would see every, but I do mean every, aircraft with winglets !

I must say, from my personal point of view, that I would have been happier with blended winglets like on the 737's. But eventually, we can say with total certainty that Airbus knows what it's doing ...

I found an article about the new wingtips.

Look at this > Flight International

On a other forum I've read this:

Expectations are that a 4-5% increase in fuel efficency (not as high as 737 (5-6%) because the airbus wing is a bit more efficent) and the big benifit will be increase in range
