Hi guys. I know what a winglet is, and thanks to this forum, a few months ago I learned about Raked wingtips. (I couldn't find a pic of a "raked" wingtip).

Can someone please tell me if there is a name for the aerodynamic feature that's on the wingtips of an Airbus A320 and other Airbuses?

Also, does it's different shape mean it provides different benefits then a winglet?

To me, it looks like half of a Flight Feather you'd find on a dart. It looks Cool!

I think they call this feature on A320-series 'winglets', and that they have no special name for this type of winglet.

Of course, I could be wrong...

Hi Apuneger. Well OK. That sure could be the case. I just thought that they might have a different name, if any, because their shape is unique.

Perhaps someone will let us know for sure.

On the A300, this item is called the Wing "Fence" or Wing-Tip "Fence". The MM states it's purpose is to reduce drag.
I guess you can call it a Winglet if you wish. I don't think anyone would mind.

Hi Mr Spaceman,

What you have on A300s, A310s and the A318/319/320/321s is called "Wing Tip Fence" and has a different size and shape than the "Winglet" you have on A330s, A340s, B744s (exept B747-400D).

The goal is the same for both: destroying the vortex created at the wing-tip and thus, reduce drag. Therefore, it reduces the fuel consumption.

Why a different shape? Sorry, no idea. If you look at the MD11, you'll get another shape too though the goal is the same again.


The sky has no limit...

Hello Gentlemen.

Thanks a lot for that info MightyFalcon & Dc10hound. I know that it was a simple question (no heavy duty technical stuff), however I've often wondered about those wingtips...and now I know their name. It's much appreciated.
