cool, never seen one of theese tests before

I watched the 777 wing break. There was so much tension on the wing it started to create ripples in the fuselage

wtf is that george lucas at 1:40?

Just one for FAA certification.

They build an airframe like the one you fly in, they then stress two components:

1) The wingbox, that big, ugly (but extremely necessary) thing under the middle of the fuselage that the wings connect to

2) The wings

In 2006 it was a big deal when the A380 wingbox failed at only 147%. They are supposed to fail at >150% for current specs of most planes.

These are stressed to the point of breaking, so they destroy these test aircraft intentionally

They breaks wing every day?for each plane made?

Interesting how it broke much more cleanly than the 777, which just shattered. I would've thought it'd be the other way around, but then, I'm no engineer.

extreme earthquake success!

@demoninepro99p they had the same problem with there a380 wing test and had to redisgn

@kdraper2007 Military aircraft have been using composites widely for years and they really dont have any problems. It is a proven technology, it just happens to be that this is the first time it's been used so much on a commercial plane. At any rate I'm sure this plane is just as safe if not more so then any other plane built in the last 15 years.

Cool video. Though this test probably yields a lot of data which is useful, I would assume they also do dynamic tests where the wing is loaded and unloaded repeatedly as you would expect it to experience in flight verses a constant applied load as seen here.

damn, they just broke millions of dollars -.- Y U no give it to me??

Don't forget that this is the SECOND wing stress test, the first, a massive failure, resulted in yet another lengthy delay in release to boeings customers. Airbus is proving far superior in so many ways.
