cool things with wheels since 2006
That's the 787 wing test that they stopped at 150% of the design load. The 777 failed at 154% of design and Boeing didn't want to snap these composite wings because they were needed for more tests like the 25,000 hour flapping test. There was a lot of excitement at work (Boeing) over this test.
I remember seeing the video of the 777 test in a programme about the aicraft's design (particularly about how the whole thing was done on one massive computer system). I think it was a BBC Horizon episode.Everyone applauded as it reached 150% without failing and then even louder when there was a big bang and collapse at 154%. You want an aircraft to be exactly strong enough for the job. Any stronger and you're just reducing payload (in effect making the plane weaker).Tony
