The composite fuselage of Boeing’s new 787 Dreamliner has passed a series of tests to determine whether the structure meets strength requirements for flight.
Boeing said its engineers stressed the fuselage barrel to its design limit and then increased the stress on the structure to 150 percent of the design load. The fuselage survived without damage.
The testing team then increased the load on the fuselage to well above test limits until engineers head audible cracks from the fuselage.
“Testers observed audible indications of damage as the test progressed but the piece did not reach the level of destruction that had been anticipated,” Boeing said.
