Blimey

WOW!

Great clip!
You don't feel so bad when you see the wings flex on a plane when they come into land!

I would expect that carbon fibre is used

Isn't carbon fiber rigid.

 

[herman1rg]

Carbon fibre and epoxy composites and titanium graphite laminate are used in the construction of the wings.

Isn't carbon fiber rigid.

No, but a stucture built of carbon fiber can be made to be rigid or flexible. Check out the flex on a carbon shaft golf club for example.

I have seen a similar video, perhaps a TV show, on when they did this for the triple 7. In that case the ultimate failure was dramatic - and loud!

Is the video available anywhere?

Yup, here you go. I think it's a clip from a Nova program. Not very good quality but impresssive nonetheless.

I am surprised at the bend in the wing. Boeing also did the B-2 but the B-2 wing is quite rigid. Probably a weight savings to allow such bend. I believe the B-2 was tested to failure.
