FTA: The extensions, each measuring several metres, will replicate a folding wing in the fully extended position during a flight

So no, they are not foldable today - the headline submitted to HN is total clickbait.

AFAICT they don't exist at all today. They are just renderings. So double clickbait. A more accurate title would be, "Airbus announces plans to develop foldable wing extensions, with non-foldable versions as the first step" or something like that.

I mean the article is not lying about it only the title here, the title there is "Airbus launches new flight test programme for Wing of Tomorrow" and it's a press release for the start of a new program in their innovation area.

"Airbus tests extended-length wings to see if it's worth developing the technology to produce folding versions of the same"

[lisper]

No, they are not testing these wings in the present, they are planning to test them in the future:

"Over the next three years, Airbus will design, build and flight test full scale wing extensions."
