May 3, 201016 yr Wing test video, check out the deflection at 150% :( : http://787flighttest.com/hanger/wp-content...le=TestLog4.flv Dan Downs KCRP
May 3, 201016 yr I presume you've seen the 777 wing test video as well? I was kinda hoping they would break the wing. I know little to nothing about the way carbon fiber takes stress, and it would be cool to watch. Joe Sherrill
May 4, 201016 yr Commercial Member I wonder if they test it also downward tooDo have any idea of how a wing works? Alex Ridge Join Fswakevortex here! YOUTUBE and FACEBOOK
May 4, 201016 yr I imagine he does. But the wing may be put under these kind of stresses in unusual circumstances, a legitimate question tbh.

May 4, 201016 yr Author You would need significantly more negative G's than any commercial airliner is rated for to bend the wing to appreciable negative camber. Also, as any mechanical engineer out there can vouch for (I'm an EE) they learn alot from the wing by just bending it. They measure lots of data such as compression/expansion stress and deflection at hundreds of locations. From that data they charaterize the design and compare it to models of the wing using finite element analysis for example. It's hard to imagine the amount of work that goes into a test like this.

May 4, 201016 yr Great Video Dan.....That is just amazing that the wing can bend that far.Still amazed with technology!!!
May 5, 201016 yr Wing test video, check out the deflection at 150% :( : http://787flighttest.com/hanger/wp-content...le=TestLog4.flv A Great and interresting video Dan!I don Leif A Mikkelsen **********************
