Multi-functional trailing edge apparatus and methods for aircraft are disclosed herein. An example wing of an aircraft disclosed herein includes an aft edge supporting a trailing edge device. The trailing edge device has a control surface and a side surface. A linkage is rotatably coupled to the side surface and the aft edge, and a rotary actuator is operatively coupled to the linkage to move the control surface.

Multi-functional trailing edge apparatus and methods for aircraft

A landing gear for use on an aircraft, the landing gear including a shock strut and an anti-rotation linkage. The shock strut is positioned at least partially within and guided in movement by a guide member coupled to a frame of the aircraft. The shock strut including an outer cylinder that is shaped and sized to engage the guide member where the guide member guides sliding movement of the outer cylinder, and where the outer cylinder is configured so as to be driven in the sliding movement relative to the guide member, and an inner cylinder disposed at least partly within the outer cylinder. The anti-rotation linkage including a connector plate coupled to the outer cylinder of the shock strut, and an anti-rotation link assembly coupled to both the guide member and the connector plate, the anti-rotation link assembly being configured to maintain the shock strut in a fixed rotational orientation relative to the guide member.

Semi-levered shrink landing gear

An aircraft includes a landing gear having a shock strut, an outer sleeve at least partially surrounding the shock strut, and a shrink mechanism coupled to both the outer sleeve and the shock strut, where the shrink mechanism moves the shock strut relative to the outer sleeve. The shrink mechanism includes a shaft rotatably coupled to the outer sleeve, an anchor arm coupled to the shaft, a shrink arm coupled to the shaft, the shrink arm and the anchor arm being coupled to the shaft so as to rotate as a unit with the shaft about a shaft rotation axis, relative to the outer sleeve, at least 180&#xb0; when the anchor arm is coupled to the structure within the wing of the aircraft, and a shrink link rotatably coupled to the shrink arm, the shrink link being configured to rotatably couple to the shock strut.

A trailing edge flap actuation mechanism has a flap drive link with a first end pivotally coupled to a fore flap structure of a flap and a second end pivotally coupled to an underwing support structure. An aft tension link has a leading end pivotally coupled proximate an aft end of the underwing support structure and a trailing end coupled to a mid-section structure of the flap. An actuator, when actuated, rotates the flap drive link about a first pivot axle to move the flap between a retracted position and a deployed lowered position. The actuator, including a ball-screw drive shaft having a universal joint, is positioned in a cove above the underwing support structure whereby the extent that the underwing support structure protrudes below the wing is reduced.

A landing gear for an aircraft comprising a truck support strut, a landing gear retract mechanism coupling the truck support strut to a frame of the aircraft, so that the truck support strut is suspended from the frame by the landing gear retract mechanism, at least one wheel support arm rotatably coupled to the truck support strut, a carrier member coupled to the landing gear retract mechanism and to the truck support strut so that the landing gear retract mechanism drives the carrier member along the truck support strut, and at least one shock absorber, each of the at least one shock absorber being coupled to both a respective one of the at least one wheel support arm and the carrier member so that movement of the carrier member effects rotation of the at least one wheel support arm relative to the truck support strut.

Body mounted shrinking landing gear

A shrink mechanism for use with a landing gear of an aircraft is provided. The landing gear includes an outer sleeve at least partially surrounding a shock strut, the shrink mechanism has a shaft rotatably coupled to the outer sleeve about a shaft rotation axis, the shaft being disposed perpendicular to a centerline of the shock strut, an anchor arm coupled to the shaft, the anchor arm being configured to couple to a structure within a wing of the aircraft, a shrink arm coupled to the shaft, the shrink arm and the anchor arm being coupled to the shaft so as to rotate as a unit with the shaft about the shaft rotation axis, and a shrink link rotatably coupled to the shrink arm, the shrink link being configured to rotatably couple to the shock strut.

A system for mechanical operation of an aircraft wing includes a torque tube rotatable at a first rate of rotation to cause a downward rotation of a control surface relative to the aircraft wing. A gearing assembly including an output shaft is coupled to the torque tube. The torque tube is configured to rotate the output shaft, via the gearing assembly, at a second rate of rotation less than the first rate of rotation. A rotational member is coupled to the output shaft, and the output shaft is configured to drive a rotation of the rotational member. A first end of a linear actuator is coupled to the rotational member at a forward attach point, which is eccentric to a rotational center of the rotational member. The rotational member is rotatable to cause a translation of the forward attach point relative to the aircraft wing.

Mechanical droop for spoiler operation

A wing assembly comprises a raked wing tip having an outboard portion hinged to one of a main wing having at least one moveable control surface and an inboard raked wing tip portion. The outboard portion of the raked wing tip does not carry any moveable flight control surfaces.

Hinged raked wing tip

Example actuator assemblies to deploy aircraft leading edge flaps and seals for aircraft leading edge flaps are described herein. An example apparatus includes an aircraft flap that is movable between a stowed position and a deployed position. The flap includes a top panel. A notch is formed in the top panel and extends into a side of the top panel near a trailing edge of the flap. The example apparatus also includes a seal coupled to the flap. The seal is movable to cover the notch when the flap is in the deployed position.

Actuator assemblies to deploy aircraft leading edge flaps and seals for aircraft leading edge flaps

An apparatus of an aircraft, the apparatus may include a wing comprising an unfixed portion and a fixed portion. The unfixed portion movably may connect to the fixed portion. The unfixed portion may include a rotating portion to rotate the unfixed portion between a flight position and a folded position. The fixed portion may connect to the unfixed portion of the wing. A joint may allow rotation of the unfixed portion of the wing with respect to the fixed portion of the wing about a rotation axis.

Horizontal folding wingtip

A fairing drive assembly couples a flap assembly of a wing of an aircraft to a fairing of the wing. The fairing drive assembly may include a fairing cam including a first joint and a second joint, and a flap link pivotally coupled to the first joint of the fairing cam and the flap assembly. A fairing drive arm is pivotally coupled to the second joint and the fairing. The fairing cam is configured to rotate upon actuation of the flap assembly and deflect the fairing away from the flap assembly.

Aircraft wing fairing drive assembly, system, and method

A variable camber Krueger flap deployment linkage mechanism is presented. A first linkage assembly couples a flap assembly and an airfoil, and comprising a first drive arm, a first drive link, and a support arm. A second linkage assembly couples the flap assembly and the first drive arm, and comprises a drive transfer arm, a middle connection segment, and a bullnose link.

High-positioned 2-position variable camber Krueger

A wing fold system may move a second portion of a wing with respect to a first portion of the wing between flight positionand folded position. A first link may rotate in response to actuating an actuator. A second link may move in response to rotating of the first link. The second portion of the wing may move in response to moving the second link and the second portion may move with respect to the first portion of the wing. One of the first portion and the second portion may be a fixed portion of the wing and the other of the first portion and the second portion may be a wingtip of the wing.
