A Boeing 787 Dreamliner has its wings bent upwards for the final stages of its static test. Woah, they bend?

Here is that very situation. Sadly all three crew members died.

Is this kind of stress likely to happen to a plane, in *any* situation?

It seems those wings are heavily over designed, but then, many people`s lives depend on it, so its justified.

That`s not even as far as they go. I`ve heard they`ll go completely vertical before failure.

Turbulence doesn`t bend wings that far, so it`s great they can handle strain of that extent.

I`m going to memorise this picture in my head, so that next time I`m in bad turbulence, watching a wing acting like Rolf Harris`s favourite instrument.. I`ll feel a bit safer.

Except... it still doesn`t model turbulence very well does it..

I actually thought it was more commonly known, but yeah all airplane wings HAVE to be flexible, some more than others ... that`s why they look so flimsy when you`re actually flying, because if you were in an emergency situation, those wings aren`t going to break off unless you hit something, and you can glide to safety if all else fails

It`s meant to be possible for them to bend so much the tips touch each other and they shouldn`t break...

Of course the wings bend, they have to be able to flap for the plane to fly. Duh.

This was a stress test to see how far they would bend without breaking. Every commercial jet has to undergo these sort of tests so that they can determine the maximum stresses the plane can take.
That data is then fed into computers that, In the future, Will help the plane fly and stay safe.

Why are people surprised that a critical thing is tested far beyond requirements? It would be more worrying if it wasn`t.

Think about it from the point of view of the manufacturer. If the wings on your planes, even just one of your planes, break off in flight even under the worst natural conditions, hundreds of people will die and your reputation will be badly damaged. So you require them to remain intact far beyond any realistic forces, to be damn sure they won`t break off short of attack or impact.

@ koala, prob didn`t word my explanation very well. The body of the aircraft is a cylinder with a radius of 5.7M (viewed front on) and the wingspan from wing tip to wing tip is 60.12M (viewed top, bottom, front or rear) this means that the total width of the aircraft, wingtip to wing tip is 10.57 times the radius of the body (60.12 divided by 5.7) remove the body from that figure as if the wings were stuck together without the body there and the span would be 9.57 times the body diamiter i.e each wing is just over 4.5 times the diamiter of the body. Which these (at a rough measurement) are far from

@biscuit29 um... look at the end of the wings, theyre not even finished, so maybe they ARE the wings.

Google boeing 787 wing break test and watch the vids or read up.. you would think that people would know to google something before calling it fake or giving false knowledge.. :/

Actually you are partially correct. While the wings of all aircraft bend slightly, airliner wings do not bend to this extreme in flight. This is, as the caption states, just a test probably to test the breaking point of the wings. Look up images of airliners in flight and you`ll see that they are pretty flat in comparison with this test. And images of the 787 at takeoff show a bend, but also not at this extreme. The only thing that comes close to this is the Pathfinder solar powered craft in terms of this amount of bending.

Pilot here.

@biscuit - following your logic, the body of the aircraft is a sphere. They extend backwards, those are the wings viewed from the front, not the side.

@manorrod - Umm, no. Those wings are filled with fuel. If they where not, the combinned weight of the fuselage + the lift of the wings would sever them form the aircraft.

Under normal circumstances, the wings do not bend that much.

Probably the only way you would see them bend that much would be through a sideways, inverse, spiral following an engine failure in a heavy crosswind.

But if that`s the case, you`d be more busy pooting yourself than looking out the window.

The wings do bend in the air. but they arent that bent.

Most people don`t realize that at 30,000 ft. the wings of all passenger jets are bent like this normally. It only seems flat when you look out the window.

I believe most planes` fuel tanks are actually "bags" or giant bladder-like things inside of compartments in the wings. At least that`s what they are inside a C-130. Anyways, I don`t think the fuel tanks/bags would rupture from torsion.

Not 100% sure what`s going on here, but don`t think they`re it`s wings. They simply don`t look long enough. Checked the dimensions of the aircraft on the boing website, and the 787 has an overall wingspan of 60.12M and a fusalage width of 5.7M which means that each wing should be just over 4 and a half times as long as the fusalage width which these definately aren`t.

This is further than they would ever bend in reality though - as Spider_sol said, they perform these tests with an enormous safety factor.

I`m an engineer and have actually worked on the engines for the 787 (sorry people, I`m afraid it does in fact have engines! No flapping for this one), and it`s true - if the wings are not super flexible then the plane will suffer badly during turbulence and the struts in the wings are very likely to fail quickly due to metal fatigue.

I think that if the wings bend this far in flight the fuel tanks inside them will rupture, the control surfaces will jam and there wont be any lift.

It`s not about real world situations, they stress them well beyond what they would experience normally so they are nearly failsafe in normal situations.

it is real radoinc, in severe winds and turbulance the wings must be able to flex or the whole plae will start to move around which could cause a crash, all the wings are actually super flexible

I wonder in what real life situation the wings could be bend that way

I`m sorry, but I call it bull***t. Sure, the wing must be flexible, but not like that. It`s probably the perspective, or simply the wings aren`t just mounted yet.

Why is it a surprise that they bend? if they were stiffer they would slowly crack and eventually break
