Embodiment Construction

[0020] Disclosed herein are example devices and methods that, prior to transitioning the wingtip from an extended position to a folded position, by moving one or more control surfaces on the wing to create more or less air load on the wingtip Multiple vantage points to control the air loads on the aircraft wingtips. Examples disclosed herein enable the use of smaller, lighter wingtip actuation systems, thereby reducing the weight of the wingtip and reducing the space required to accommodate the wingtip actuation system in the wing of an aircraft. As a result, the wings can be thinner and lighter and thus result in more efficient flight.

[0021] Before turning to detailed aspects of the disclosed aircraft control systems and methods, a brief discussion of folding wingtips is provided. It is generally known that longer, lighter and / or thinner wings are more aerodynamically efficient than shorter, heavier wings. Likewise, a higher aspect ratio wing produces more efficient flig...

Abstract

Disclosed herein are methods and apparatus for controlling a wingtip of an aircraft for moving control surfaces on an aircraft to control air loads during wingtip folding operations from a folded position to an extended position or from an extended position to a folded position. An example method includes determining a position of a control surface on a wing of an aircraft. In an example approach, an airfoil has a fixed wing portion and a wingtip movably coupled to the fixed wing portion. An example method includes determining a change in position of a control surface from a first position to a second position that facilitates movement of the wingtip when the aircraft is not in flight. The example method also includes moving the control surface to a second position and moving the wingtip between an extended position and a folded position.

Description

technical field [0001] The present disclosure relates generally to aircraft folding wingtips and, more particularly, to controlling airload on aircraft folding wingtips. Background technique [0002] Larger aircraft have longer wingspans, which tend to result in more efficient flight. However, the taxiway spacing and gate locations at most airports do not provide sufficient spacing to accommodate such large wingspans. Therefore, longer wingspan aircraft usually employ folding wingtips. After landing, the wingtips (up, down, forward, backward or a combination thereof) are folded to reduce the aircraft's wingspan. Contents of the invention [0003] Example methods disclosed herein include determining a position of a control surface on a wing of an aircraft. In an example approach, an airfoil has a fixed wing portion and a wingtip movably coupled to the fixed wing portion. An example method includes determining a change in position of a control surface from a first positi...
