  • Patent number: 11572158
    Abstract: 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° 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.

  • Patent number: 11034432
    Abstract: 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.

  • Patent number: 10766602
    Abstract: 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.
