Boeing Wing Stress Test
United Kingdom
Boeing has completed the ultimate load wing up-bending test on the 787 static test unit, ZY997, at its facility in Everett, Washington.
The airframer says that it applied loads to replicate 150% of the most extreme forces the airplane could experience while in service, resulting in the wings being flexed upward by approximately 25ft (7.6m) during the test. In order to achieve certification, the US FAA requires aircraft structure to withstand 150% of limit loading for 3s.
The company says that during every second of the over two-hour test, thousands of data points were collected to monitor the performance of the wing.
