Abstract

Aerospace vehicle fairing systems and associated methods, including fairings that house flap surface drive mechanisms on aircraft, are disclosed herein. A method in accordance with one embodiment, for example, can include adjusting lift distribution across an airfoil. The airfoil includes a first inboard portion and a second outboard portion. The method can include locating a point of maximum curvature of a first fairing at least approximately forward of a trailing edge of the airfoil proximate to the first inboard portion. The method can also include locating a point of maximum curvature of a second fairing at least approximately aft of a trailing edge of the airfoil proximate to the second outboard portion. The locations of the points of maximum curvature for the first and second fairings are based, at least in part, on a target lift distribution.

Claims

1. A method for manufacturing a wing, the method comprising:

locating a first fairing and a second fairing proximate to the wing, the individual fairings including a first side and a second side laterally displaced from a longitudinal axis, wherein the first and second fairings each house (a) at least a portion of a drive mechanism configured to move one or more movable surfaces of the wing, (b) at least a portion of one or more supports associated with the corresponding movable surface, or (c) both (a) and (b);

mounting the first fairing to the wing with a point of maximum curvature for at least one of a first side and a second side of the first fairing located approximately forward of a trailing edge of the wing; and

mounting the second fairing to the wing outboard of the first fairing and with a point of maximum curvature for at least one of a first side and a second side of the second fairing located approximately aft of the trailing edge of the wing.

2. The method of claim 1 wherein:

mounting the first fairing to the wing comprises mounting the first fairing with both the point of maximum curvature of the first side and the point of maximum curvature of the second side of the first fairing located forward of the trailing edge; and

mounting the second fairing to the wing comprises mounting the second fairing with both the point of maximum curvature of the first side and the point of maximum curvature of the second side of the second fairing located aft of the trailing edge.

3. The method of claim 1 wherein:

mounting the first fairing to the wing includes mounting a first flap fairing to a wing having a movable flap surface, the first flap fairing housing at least a portion of a drive mechanism for the flap surface, the wing being coupled to a fuselage of an aircraft; and

mounting the second fairing to the wing includes mounting a second flap fairing to the wing and movable flap surface, the second flap fairing housing at least a portion of the drive mechanism for the flap surface.

4. The method of claim 1 wherein at least a portion of the first fairing and the second fairing are configured to move when the corresponding drive mechanism moves the one or more movable surfaces.

5. The method of claim 1 wherein mounting a first fairing and a second fairing to the wing comprises mounting the first and second fairings to a wing that is couplable to an aerospace vehicle.
