MY FAULT RE WORD ORDER - 777X WAS NODT A WING TEST - IT WAS A PITCH ON THE BOEING 777X WING

Join us TODAY at 10:00 AM PDT (17:00 UTC) LIVE from the Everett factory! We're chatting with the amazing 777X team and getting an exclusive view of the world's most advanced composite wing. Our host, Jeff Haber, and 777X mechanic, Hillary Anderson, will share more on how these giant wings will help make the 777X the most efficient large twin-engine airplane in the world.
Remember to leave your questions in the comments of the Facebook post or by tweeting at @BoeingAirplanes on Twitter.

CONSO,
I guessed that the word order was wrong, but it was too good an opportunity to miss. ;)

Reminds me of some diving board we made at the lake when I was 11 years old. We destructive tested just about everything we made,,,
Never mind me.
How fare did they get before it snapped?

I guess when you're flying and you begin to hear those pops and bangs it time to read the safety card i the seat pocket

It was NOT a wing test but a TEST WING PR FOR 777X- MY GOOF :\
SO AS A MEA CULPA HERE IS AN OLD 777 FIRST MODEL WING TEST TO DESTRUCTION- ABOUT 4 PERCENT ABOVE REQUIRED MAX/ULTIMATE LOAD AND IT BROKE WITHIN A FEW INCHES OF PREDICTED LOCATION ON UPPER PANEL

CONSO,
Thanks for posting that 777 limit load test. Very impressive.
Do do you know how they held the fuselage down? Via the gear or straps?

I'm sure tdracer can get more detailed - but generally they use ' in broad terms straps' fore and aft of the wing box going around the fuselage and a ' strap' a bit forrward of the horizontal stabilizer area.
On the 767 program, when they ran the same test- as they go close to 150 percent limit load, the ' aft ' fuselage section twisted as in wringing a towel so the test was stopped. The result was that they had enough data to meet cert requirements. But they removed the plane and put it in the boneyard near the plant. A close look of the plane showed that that the ( rudder )( vert stabilizer skeleton was about 5 to 10 degrees from vertical. The reason was a manufacturing error which left out a circumferential ( hoop ) near the rear exit door.
generally, depending on data and percentage loads, going to full destruction is NOT a requiement. Boeing did not destroy the 787 wing because the required loads plus sa small margin was obtained- and taking it much further to break was simply NOT worthwhile. I'm sure a search boeing video or still will show just how much the 787 wijngs ere deflected up -it is spectacular

Breaking CFRP is tricky and dirty.

Seems to have worked this time!

To be a little more precise, driving the full scale wing to destruction is not a requirement, if you can support your calculation and test results with destructive tests on component or coupon level.
Every design detail on the wing has to be driven to destruction, but this can be done in smaller scale tests. Due to the heavy deformation, stress in some components is not rising linearly with load, this needs to be somehow determined by the full scale test to relate the (simple) cupon loading to the (complex) full scale loads.
Breaking CFRP is tricky and dirty.
and dangerous... For metal a lot of the energy is dissipated by plastic deformation, for CFRP practically all energy introduced is stored elastically in the material and set free at the moment of failure!
This can be quite violent sending some parts, fragments, loading or measurement equipment flying through the hangar even breaking through walls...

There is another video from Denmark before siemens acquired Bonus that would also, err, make you wince....
..It features a blade test along the lines of HEY! I know what we can do today
otherwise entitled how to shock load a cantilever crane to destruction...hard hats optional...
This lot are professional at it.
Note anchor point[s] for blade attachment. Big Boys Toys.

Nor get them piercing your skin. A friend of mine had to wait two years for a carbon fiber splinter to work its way out of his hand.
