Ground testing was recently conducted on the wing of the DarkAero 1 prototype to characterize the wing root rib angular deflection under load. Let’s go into a bit more detail on why this was done: Lift loads bend the wings, which results in angular deflection in the wing root ribs where the wing attaches to the fuselage. Measuring this angular deflection allows the same deflection to be applied to the fuselage wing attach lugs during respective proof load testing. This helps ensure ground testin
