Abstract: A driveshaft includes a first end, a second end, and a length extending from the first end to the second end. The driveshaft includes an engagement section at the first end configured to cooperatively engage and transfer torque to a gearbox. The driveshaft also includes a compressible section configured to selectively decrease the length of the driveshaft. The driveshaft being configured to transition between an engaged configuration, wherein the engagement portion is engaged with the gearbox, and a disengaged configuration, wherein the compressible section is compressed, and the engagement portion is disengaged from the apparatus.

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 a drive component 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 is misaligned with the retractable driveshaft when the wing assembly is in the stowed position. A seal is coupled to the drive component at a first end and the mid-wing gearbox at a second end and deploys in order to maintain a sealed connection between the drive component and the mid-wing gearbox when the wing assembly is transitioned between the flight position and the stowed position.

Abstract: Briefly, the disclosure relates to apparatuses and methods to form a gearbox enclosure comprising an external liner, an internal liner, and a variable porosity region disposed between the external liner and the internal liner. The variable porosity region may be configured to accommodate flow of the lubricant, thereby providing a capability to cool, for example, a lubricating fluid at an elevated temperature.

Abstract: Various implementations described herein are directed to an emergency lubrication system for a tiltrotor aircraft. The emergency lubrication system includes a pressurized material chamber, a lubrication chamber, a first valve between the pressurized material chamber and the lubrication chamber, a gearbox, and a second valve between the lubrication chamber and the gearbox. The first valve is configured to operate in a first mode when the emergency lubrication system is in a first configuration and a second mode when the emergency lubrication system is in a second configuration.

Abstract: An embodiment of the present invention provides an aircraft that includes a fuselage and a rotatable wing disposed above the fuselage. At least one cross-wing driveshaft is disposed within the wing and is driven in rotation by a drive system connected to first and second engines that are located at respective sides of the fuselage beneath the wing. The drive system is so configured that one or both of the first engine and the second engine can drive the at least one cross-wing driveshaft in the event of failure of an engine.

Abstract: A cam-locking system for use with a retractable driveshaft that includes a housing, a cam carrier located at least partially in the housing, and a cam rotatably coupled to the cam carrier. Translation of the cam carrier along a central axis allows the cam to rotate into cooperative engagement with a catch recess on an interior surface of the housing, preventing the cam carrier from translating backwards, and thereby maintaining the retractable driveshaft in an engaged position. Further advancement of the cam carrier allows that cam to rotate into and unlocking gap in the interior surface of the housing, which enables the cam carrier to translate backwards along the central axis below the locked position, thereby disengaging the retractable driveshaft.
