During testing, the wings were flexed upward by approximately 7.6m.
The initial results of the ultimate-load test are said to be positive but Boeing stressed that more extensive analysis and review are required.
‘The test programme has been more robust than any conducted on a Boeing commercial jetliner,’ said Scott Fancher, vice-president and general manager of the 787 programme, Boeing Commercial Airplanes. ‘We are looking forward to the technical team’s report on the details of the test results.’
During each second of the test period, thousands of data points were collected to monitor the performance of the wing. Key data points are monitored in real time during the test, but all of the data will be evaluated in the weeks ahead.
The 787 Dreamliner is Boeing’s new twinjet designed to provide a non-stop service between mid-size cities.
Delivery of the first 787 is planned for the fourth quarter of 2010.
