ADDITIVELY MANUFACTURED LUBRICATION CHANNELS
An additively manufactured component for a landing gear assembly may comprise a lug and a lubrication channel extending through the lug. The lubrication channel may comprise an inlet and an outlet. The outlet may be located at a pin orifice defined by the lug. A center axis of a first portion of the lubrication channel may be oriented at an angle relative to a center axis of a second portion of the lubrication channel.

FOLDING MAIN LANDING GEAR FOR CARGO AIRCRAFT
Systems and methods for folding landing gear of a cargo aircraft. One embodiment is a main landing gear of an aircraft that includes a shock strut coupled to a truck with one or more wheels, and a yoke pivotally coupled with the shock strut via a lower trunnion, and pivotally coupled with an aircraft structure via an upper trunnion. The yoke is configured to pivot about the upper trunnion in a direction back toward a tail of the aircraft and up toward a fuselage of the aircraft, and the shock strut is configured to pivot about the lower trunnion in a direction forward toward a nose of the aircraft and up toward the fuselage of the aircraft to retract the one or more wheels.
LANDING GEAR FOR CARGO AIRCRAFT
Systems and methods for wide set retracting landing gear of a cargo aircraft. One embodiment is an aircraft that includes a fuselage including a nose, and a pair of main landing gears comprising a pair of main posts disposed across the fuselage, each main post having a main wheel and configured to pivot forward toward the nose to retract the main wheel. The aircraft also includes a pair of nose landing gears comprising a pair of nose posts disposed across the fuselage, each nose post having a nose wheel and configured to pivot inboard to retract the nose wheel.
PIVOTING MAIN LANDING GEAR FOR CARGO AIRCRAFT
Systems and methods for pivoting main landing gear of a cargo aircraft. One embodiment is a main landing gear of an aircraft that includes a shock strut coupled to a truck with one or more wheels, and a trunnion coupled to a bulkhead and configured to pivotally couple the shock strut with the bulkhead. The main landing gear also includes a folding brace extending from the shock strut in a forward direction toward a nose of the aircraft and configured to stabilize the shock strut. The main landing gear further includes a retraction actuator configured to pivot the shock strut about the trunnion to retract the one or more wheels in the forward direction toward the nose and up toward a fuselage of the aircraft.
Landing gear support
An aircraft landing gear support (1) including: a support member (such as a landing gear rib (2)) and a plurality of pintle supports (5, 7, 8) (typically in the form of lugs) which form a pintle support arrangement for holding a pintle on which a landing gear assembly may be rotatably supported. The lugs are removably attached to the gear rib.

Non-jamming shrink latch mechanism
A non jamming shrink latch is provided and may comprise a cradle, a first rocker arm, a first inboard pivot, and a first outboard pivot, wherein the first inboard pivot is coupled to the first rocker arm at a first end and the first outboard pivot is coupled to the first rocker arm at a second end opposite the first end, and wherein the cradle is coupled to the first outboard pivot. In various embodiments, a non jamming shrink latch may further comprise a second rocker arm coupled to the cradle at a second outboard pivot and a second inboard pivot coupled to the second rocker arm opposite the second outboard pivot.

SYSTEM AND METHOD FOR LANDING GEAR RETRACTION
A retractable landing gear on an aircraft is operated by a landing gear control system 20 having a manually operable lever 26 movable from a first, e.g. gear-down, position to a second, e.g. gear-up position, in response to which a signal (e.g. a gear-up command) is outputted causing the landing gear to move to an up position. The landing gear control system 20 also includes a motor 40 configured to move the lever 26 in dependence on a signal, for example a signal received by a landing gear lever control unit 42 from a take-off detection system 46 which indicates that the aircraft has taken-off. Thus, the lever 26 may be considered as being configured both to be operated by a pilot of the aircraft manually and to be operated by the motor automatically.
