EVERETT, Wash., April 7 /PRNewswire-FirstCall/ -- Boeing (NYSE: BA) announced today that all test requirements were successfully met during the 787 Dreamliner’s ultimate load wing and fuselage bending test. This follows a thorough analysis of the results from a test on the 787 static test airframe.
“Successfully completing this test is a critical step in the certification of the 787. This is further validation that the 787 performs as expected, even in the most extreme circumstances,” said Scott Fancher, vice president and general manager of the 787 program for Boeing Commercial Airplanes.
On March 28, loads were applied to the test unit 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 and the fuselage was pressurized to 150 percent of its maximum normal operating condition.
In evaluating the success criteria for the test, Boeing specialists have been poring over the thousands of data points collected during the test to ensure that all parts of the airplane performed as expected.
“The airframe performed as designed and retained the required structural integrity. These results continue to validate the design of the 787 as we move toward certification,” explained Fancher.

The Boeing 787 completed the ultimate wing load test which requires that the wings of a fully assembled aircraft be loaded to 150% of design limit load and held for 3 seconds. The wings were flexed approximately 25 feet upward during the test. Unlike the 777 however, the wings were not tested to failure. After carefully reviewed the test data, the Boeing announced that analysis of the data showed the ultimate load test was a success on April 7, 2010.

The Boeing 787 flight test program is composed of six -8 aircraft, ZA001 through ZA006. The first four aircraft are Rolls-Royce Trent 1000 powered jets while the last two are GE GEnx-1B64 powered. ZA001 on December 12, 2009 completed high speed taxi tests, including post-rotation takeoff abort, the last major step before flight.
Boeing plans to exhibit the 787 at the 2010 Farnborough Airshow in Great Britain which is scheduled FIA July 19 to 25, 2010.
The Boeing 787 Dreamliner is a super-efficient commercial airplane that applies the latest technologies in aerospace. The airplane will carry 210 to 330 passengers and fly 2,500 to 8,500 nautical miles, while providing dramatic savings in fuel use and operating costs. Its exceptional performance will come from improvements in engine technology, aerodynamics, materials and systems. It will be the most advanced and efficient commercial airplane in its class and will set new standards for environmental performance and passenger comfort. The 787 family also inlucdes VIP versions, which provide more than 2,400 square feet of cabin space and can fly its owners almost anywhere in the world nonstop.
The lists shows 671 for 787-8 orders, 195 orders for 787-9 and the total 866 firm orders for the Boeing Company Dreamliner 787 as of February 25, 2010. Many media shows that there are more 787 Dreamliner orders to be counted for the Boeing Company when the final decision have been made by the customers: Air Algerie, Austrian Airlines, El Al, Delta Air Lines, British Airways, Pakistan International Airlines, Emirates, Orient Thai Airlines, GMG Airlines, Air France-KLM, and Thai Airways. The most fuel-efficiency 787 dreamliners will be able to fly everywhere and anywhere whereever they need to be....
