SYSTEM AND METHOD FOR CONTROLLING AIRCRAFT FLIGHT CONTROL SURFACES

Abstract:

Methods, systems, and assemblies for controlling flight control surfaces of an aircraft wing are described. The method comprises displacing a first trailing edge of a first flight control surface towards a contact surface of a second flight control surface; determining a mechanical stiffness of the first flight control surface as defined by a ratio of .DELTA.F/.DELTA.X as the first flight control surface is displaced, where .DELTA.F is a difference in force F applied to at least two different positions X1 and X2 of the first flight control surface at times T1 and T2, and .DELTA.X is a difference in position X2-X1; and achieving full contact between the first trailing edge and the second leading edge when a known full contact mechanical stiffness is reached.
