摘要： 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.

摘要： An aircraft spoiler mechanism includes a spoiler fore-section, a spoiler aft-section, and a reverse-motion linkage arm. The spoiler fore-section includes a forward end, a hinge end, an actuator coupling, and a pivot coupling to couple to a wing structure of an aircraft to enable rotation of the spoiler fore-section relative to the wing structure. The spoiler aft-section includes a hinge portion coupled to the hinge end of the spoiler fore-section and a crank-arm. The reverse-motion linkage arm includes a first end, a second end, and a pivot point coupled to the forward end of the spoiler fore-section. The spoiler mechanism also includes a first linkage to couple the first end of the reverse-motion linkage arm to the wing structure and a second linkage coupled to the second end of the reverse-motion linkage arm and to the crank-arm on the spoiler aft-section.

摘要： Assemblies for air vehicle control surfaces and related methods are disclosed. An example apparatus includes a control surface; a bullnose carried by the control surface, the bullnose moveable relative to the control surface; a first actuator operatively coupled to the control surface to cause the control surface to rotate; and a second actuator operatively coupled to the control surface, the second actuator to cause the bullnose to move from a first position to a second position to cause an opening to be formed relative to the control surface, the movement of the bullnose independent of rotation of the control surface.

摘要： Linkage assemblies for moving tabs on control surfaces of aircraft are disclosed herein. An example aircraft includes a wing including a fixed wing portion and a trailing edge control surface. The trailing edge control surface includes a fore panel rotatably coupled to the fixed wing portion and an aft panel rotatably coupled to the fore panel. The wing also includes a linkage assembly including a rocking lever rotatably coupled to a bottom side of the fore panel, a trailing edge link having a first end rotatably coupled to the fixed wing portion and a second end rotatably coupled to the rocking lever, and an aft panel link having a first end rotatably coupled to the rocking lever and a second end rotatably coupled to a bottom side of the aft panel.

摘要： Flap actuation systems for aircraft are described herein. An example flap actuation system includes a fixed beam coupled to and extending downward from a fixed wing portion of an aircraft wing and a rocking lever plate pivotably coupled to the fixed beam. The rocking lever plate is coupled to a forward end of a flap bracket disposed on a bottom side of a flap of the wing. The flap actuation system also includes a crank arm, a crank rod coupled between the crank arm and the rocking lever plate, and a flap link coupled between the rocking lever plate and an aft end of the flap bracket, such that actuation of the crank arm pivots the rocking lever plate to move the flap between a stowed position and a deployed position relative to the fixed wing portion.
