Check out this official XWB photo. Are those raked wingtips? Would such a thing be patentable?

Or are they winglets or non-planar extensions?

Quoting BlueSky1976 (Reply 1):
They are winglets.

Only in the sense that they are on the end of the wing. They are clearly not traditional winglets and appear very much so to be raked wingtips.

Quoting N328KF (Thread starter):
Are those raked wingtips? Would such a thing be patentable?

Compared to this, this, or this, I don't see how they aren't raked wingtips.

In terms of patent issues: intellectual copyright does not extend to "original" adaptations. All Airbus must do is demonstrate that their wingtip is sufficiently unique from a patented concept and they are in the clear. Boeing surely couldn't patent every wingtip design so I doubt Boeing has an issue to protest.

I doubt that raked wingtips are in general patentable by Boeing. For example on sailplanes they are used, for many years.

As far as I can tell, this picture shows the regular winglets we have seen on previous A350XWB renderings. The reason why they appear different is due to the perspective of the image. If the picture were from the top or from the front/side, you would see a more regular winglet profile.

I think they are clearly winglets, just blended rather than the current A330/340 angled ones.

There was a video of the A350XWB at it's launch and it showed the aircraft on the ground with what was clearly winglets which curve upwards and backwards like raked winglets but not raked wingtips. I will look for the video on Airbus.com.

The video helps add perspective. From the first picture, they simply look like flat (or only slightly swept) wingtips. The video makes them appear much more like the 787 swept wingtip or something closer to the AVBP winglet.

This latest generation of aircraft (787, A350, etc) is reflecting hybrid wing devices that no longer cleanly fit into the "winglets" or "wingtips" categories.
