Boeing completes 787 Dreamliner static test

The wing and trailing edges of the airframe were subjected to their limit load, about 2.5 times the force of gravity; assessment of test results are expected within the week.

The Boeing Co. (Everett, Wash., USA) on Nov. 30 announced that it has completed the static test necessary to validate the side-of-body composites modification made to the 787 Dreamliner. The company expects a full analysis of the test results to be concluded in approximately 10 days. A successful test result is needed to clear the airplane for its planned first flight next month.

During the test on the 787 static test airframe, the wing and trailing edges of the airframe were subjected to its limit load — the highest loads expected to be seen in service. The load is about the same as 2.5 times the force of gravity for the wing.

Boeing announced on June 23 that it was necessary to reinforce an area of structure at the side-of-body section of the 787. The modification entails installing new fittings at 34 composite stringer locations within the joint where the wing is attached to the fuselage. The modifications were completed on the first two flight-test airplanes and the full-scale static test airplane earlier in November.

"Today's test was an important milestone for the program. We will confirm the test results after the completion of our detailed analysis," said Scott Fancher, vice president and general manager of the 787 program.
