How does Boeing test the wings of its aircraft

Boeing's hopefuls 787 is on course. Late on Sunday, the long-haul pilot successfully completed the stress test for the wings. They were strained for two hours and bent up to 7.6 meters upwards. This corresponds to an overuse of 150 percent. "The test program is tougher than any other Boeing airliner," said project manager Scott Fancher.

The aircraft is made of composite materials and should therefore be lighter than classic aircraft made of aluminum. In addition, the 787 should offer passengers more space. The new materials caused a lot of trouble during the development phase and set the project back years. Quite a few customers then jumped out. The first machine will continue to be delivered to the first customer ANA in the fourth quarter of 2010.

In the middle of last year, the Dreamliner failed a similar stress test. Damage occurred at the seam between the fuselage and the wings. In the meantime, the question arose whether the new materials would even meet the tough requirements. The whole project seemed in jeopardy. Boeing made it clear that the current test data would have to be evaluated intensively in the coming weeks until a final result was available.
