Boeing has begun preparing their static test 777X for fatigue testing


Boeing has begun preparing their static test 777X for fatigue testing by setting the aircraft up in its “cage”, indicating major structural tests are just around the corner. The aircraft, a 777-9 with designation WY987, was transferred from the 40-51 apron at Paine Field to the west parking lot on Sunday May 11th before heading down Perimeter Road to the 40-41 fatigue test structure. Boeing prepares 777X for fatigue testing Paine Airport (Matt Cawby) – Twitter What looks to be the skeleton of a large hangar is actually a complex steel structure weighing around 680t (1,500,000lb) that will tie itself to the aircraft and simulate different loads on all major components, imitating everyday operations in a worst case environment. A large collection of pulleys, steel cable and hydraulic actuators will twist, pull, push and vibrate the aircraft, with sensors gathering data for engineers to analyse. The last time Boeing used a full-scale fatigue test structure was 10 years ago with the 787 Dreamliner.
