Boeing's New 787 Wings — Amazingly Flexible

An anonymous reader writes "Boeing is making the wings of its new 787 out of carbon fiber instead of metal. That means the wings are so strong and flexible that they could bend upward and touch above the fuselage — or come close. The company is expected to deliver the first 787 to All Nippon Airlines in May 2008. 'Boeing has completed static testing of a three-quarter wingbox, but engineers are still considering whether to limit testing of the full wing to a 150% load limit held for 3 sec. or to continue bending it to see when it breaks. 'There's a raging debate within the engineering team to see if we should break it or not,' says [787 General Manager Mike] Bair.'" They have come a long way in wing flexibility.

      To be truly "tuner", the exhaust tip needs to be at least twice the diameter as the actual exhaust. Just to make it look fast.

    No, you are wrong. Boeing use good old US carbon fiber, while the Europeans use that low rent carbon fibre stuff. No comparison at all. Carbon fibre comes in litres and the fibre length is in metres, while carbon fiber comes in gallons (or perhaps liters) and fibers are measured in feet, (or perhaps meters). See how easy they are to distinguish?

    Seriously though, that idea isn't useful only for entertainment and cool effects, it is useful to know the tipping point, what boundaries they're actually working with, and not just to see if it does or does not work. And as they so often tell there -- the only way to know for sure is to test it in the real world on a non-scale model!

    What I think will happen is that tips will meet. They'll try to compress the wings vertically, but before any definitive results are in, there will be a very loud "SPROING" in which case, the wings will be freed from their restraints. They will smash toward ground, propelling the plane into the air. As they bounce back to equilibrium the wings will flap carrying the plane roughly 1000km in the direction it was pointed. Eliminating the need for any fuels on short trips. Carbon Fiber FTW!
