Boeing's making some bold claims in a Wired article about their new carbon-fiber wings for the 787 airplane.|
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. of 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.
Here's what happened to the old wings at 154% load.
I vote they break these, too. If it can handle that much more, then they could probably lighten the wings a bit and improve fuel economy.
