Ultimate load wing test on 787 Dreamliner completed by Boeing

Boeing  have completed the ultimate-load wing up-bending test on the 787 Dreamliner static test unit. During the testing, loads were applied to the airframe to replicate 150 percent of the most extreme forces the aircraft is ever expected to experience while in service. The wings were flexed upward by approximately 25 feet (7.6 meters) during the test.

The initial results of the ultimate-load test are positive. More extensive analysis and review are required before the test can be deemed a success.

“The test program has been more robust than any conducted on a Boeing commercial jetliner,” said Scott Fancher, vice president and general manager of the 787 program, Boeing Commercial Airplanes. “It has taken countless hours of hard work by the Boeing team and our partners to work through the static test program. Everyone who has been involved in this effort over the past several years should be very proud of their contributions to ensuring the safety of the 787 Dreamliner.

“We are looking forward to the technical team’s report on the details of the test results,” said Fancher. It will take them several weeks to work through all of the data.

During each second of the more than two-hour test, thousands of data points were collected to monitor the performance of the wing. Key data points are monitored real-time during the test, but all of the data will be evaluated in the weeks ahead.
