Rigid and Flexible Body Simulation of an Aircraft Wing Test Rig
Every airplane passenger who has ever sat next to the wing in rough air has surely noticed how much deflection it can undergo, and has likely hoped that the wing bending tests have been thoroughly performed! The truth is that these tests go far beyond what the passenger will ever see. Wing reliability under extreme loading conditions is tested with deflections of over 5 meters between the utmost downward and upward positions of the cycle. Similarly, the fuselage is pressurized during testing to levels that would never be encountered in normal operating conditions.
