A high-lift device surface and associated method of designing the high-lift device surface is described. Methods include entering one or more flight conditions, and receiving aerodynamic forces at a wing, the wing comprising a fixed portion, a seal coupled to and extending from the fixed portion of the wing, and a high-lift device surface having an as-built shape determined based on an anticipated deformation during flight. Methods also include deforming the high-lift device surface based, at least in part, on the received aerodynamic forces, contacting, based on the deforming, the high-lift device surface with the seal, wherein the deforming causes the high-lift device to deform from the as-built shape to a second shape, and wherein the contacting causes the high-lift device to fully contact the seal to prevent air flow between the seal and the high-lift device surface due to the received aerodynamic forces.

Wing flap deflection control removal

Example articulation assemblies for retracting aircraft flap support fairing tailcones and related methods are described herein. An example flap support fairing disclosed herein includes a housing to be coupled to a bottom side of a flap on a trailing edge of a wing of an aircraft, a tailcone disposed outward from an aft end of the housing, and an articulation assembly configured to move the tailcone between an extended position in which a portion of the tailcone is disposed beyond the aft end of the housing and a retracted position in which the portion of the tailcone is disposed within the housing.

Articulation assemblies for retracting aircraft flap support fairings and related methods

A wing flap includes a flap body and a torque member. The torque member is integrally formed with at least a portion of the flap body.

Wing flap with torque member and method for forming thereof

A wing flap includes a flap body. The flap body includes an upper skin, a lower skin opposite the upper skin, and a plurality of spars that extend between the upper skin and the lower skin. The wing flap also includes a torque member that is coupled to the flap body. A portion of the torque member is contiguous with at least one of the upper skin and the lower skin.

A high-lift device surface and associated method of designing the high-lift device surface is described. The flap can be attached to a wing on aircraft. The method can involve determining a manufactured shape of the flap. The manufactured flap shape can be deflected in some manner, such as bent or twisted, so that under selected flight conditions, such as cruise, the manufactured flap shape morphs into a second desired shape that satisfies specified constraints, such as geometric and sealing constraints. An advantage of the approach is that the flap doesn't have to be mechanically forced, using mechanical elements, into the second desired shape. The elimination of the mechanical elements results in weight and cost savings to aircraft on which the flap is deployed.

An apparatus for loading and unloading a main landing gear ('MLG') of an aircraft includes a fixture that is adapted to couple to a truck of the MLG such that a sagittal plane of the fixture is parallel to or coplanar with a sagittal plane of the MLG and both translational forces and turning moments applied to the fixture are coupled directly through the fixture to the MLG, a mechanism for controllably translating the fixture in the sagittal plane thereof, and a mechanism for controllably rotating the fixture in the sagittal plane thereof.
