Abstract: Systems and methods include providing an aircraft with a fuselage and a wing assembly rotatable relative to the fuselage about a stow axis between a flight position and a stowed position. The aircraft includes an engine reduction gearbox having a retractable driveshaft that selectively engages the mid-wing gearbox via axially translatable motion along a rotation axis when the wing assembly is in the flight position. The mid-wing gearbox includes a plunger seal that is displaced in response to contact with the retractable driveshaft. Displacement of the plunger seal allows lubricant to flow through an inner bore in the retractable driveshaft, across splines of the retractable driveshaft and the mid-wing gearbox, and through lubrication ports in the mid-wing gearbox to lubricate the engine reduction gearbox, splines of the retractable driveshaft and the mid-wing gearbox, and the mid-wing gearbox via a single lubrication system.

Abstract: A wing for an aircraft includes a first end, a second end, and a skin extending longitudinally from the first end to the second end. The wing also includes at least one channel positioned within the skin and extending longitudinally between the first and second ends. The at least one channel defines a longitudinal translation path for translating at least one electrical power source longitudinally between the first and second ends.

Abstract: Various implementations directed to managing access for a manufacturing system are provided. In one implementation, a method may include receiving access management request data at an automated provisioning system of an entity. The method may also include determining ready task data based on the received access management request data. The method may further include transmitting provisioning request data based on the determined ready task data. The method may additionally include transmitting status request data after a predetermined amount of time. The method may also include receiving the external status data. The method may further include determining generic status data based on the received external status data. The method may additionally include performing access management operations based on the determined generic status data. The method may also include manufacturing physical components using the manufacturing system based on the access management operations.

Abstract: A wing apparatus and aircraft are described providing greater maneuverability and efficiency for vertical takeoff and landing vehicles. Use of a fowler flap is shown in combination with a sliding panel. The sliding panel can nest within a wing similar to a fowler flap. During vertical maneuvers the sliding panel can be moved forward and on top of the wing. This can alleviate download during vertical maneuvers while minimizing drag as forward flight begins.

Abstract: An aircraft is described with both VTOL (vertical takeoff and landing) capabilities and convention airplane capabilities. A preferred embodiment comprises a fuselage and fixed wing, with one boom on either side of the fuselage. Each boom comprises a tilt rotor on a fore end and a fixed rotor on the aft end. Both rotors can be directed vertically for VTOL capability. During cruise the tilt rotors can be directed forward for thrust and the fixed rotors can be stopped and directed along the boom axis, minimizing drag. The described embodiments have advantages in weight savings and maneuverability compared to other VTOL aircraft.

Abstract: A system for retaining a folded proprotor blade in flight. The system includes a rotary actuator mechanism operable to generate torque via a shaft that rotates about an axis generally parallel to a chordwise direction of the folded proprotor blade, a pair of clamping arms movable in a direction generally parallel to a beamwise direction of the folded proprotor blade, a pair of linkage arms interoperably responsive to the rotary actuator mechanism and coupled between the rotary actuator mechanism and the pair of clamping arms, and a first guide rod extending between the pair of clamping arms in the direction generally parallel to the beamwise direction.
