777x wingtest today 10amPDT
TO CORRECT MY GOOF- CANNOT CHANGE TITLE HERE IS AN OLD 777 WING TEST TO DESTRUCTION OVER 20 YEARS AGO
+++++ MY FAULT RE WORD ORDER - 777X WAS NODT A WING TEST - IT WAS A PITCH ON THE BOEING 777X WING https://www.facebook.com/Boeing/ https://twitter.com/BoeingAirplanes 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. When it is time, click the images below to join us live on Facebook or Twitter. |
Are they going to do this to it? :E

Live from Everett:
Well, recorded. |
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

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 https://www.google.com/search?q=777+...firefox-b-1-ab |
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? |

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! |
generally, depending on data and percentage loads, going to full destruction is NOT a requiement. 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. This can be quite violent sending some parts, fragments, loading or measurement equipment flying through the hangar even breaking through walls... |
And you don't want to inhale those chips and dust. It would be messy.

Maybe it's just me but I wouldn't want to stand next to it.

Sorry going a bit off tangent..

..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. https://cimg8.ibsrv.net/gimg/pprune....01d2682eec.jpg BLAEST selected to test the world?s largest wind turbine rotor blade History No affiliation and well out of the industry now. |

...and contrary to glass fibre splinters you can at least see them under your skin...
