Boeing Completes Ultimate-Load Wing Test on 787
Boeing has 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 airplane 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.
The 787 Dreamliner is 'an all-new twinjet designed to meet the
needs of airlines around the world in providing nonstop service
between mid-size cities with new levels of efficiency. The airplane
will bring improved comfort to passengers with larger windows,
bigger baggage bins and advances in the cabin environment,
including lower cabin altitude, higher humidity and cleaner air.'
Delivery of the first 787 is planned for the fourth quarter of
2010.
