Abstract: Embodiments are directed to a rotor system for an aircraft comprising a gearbox configured to receive torque from a drive train, a mast having a first end and a second end, wherein the first end is attached to the gearbox and the mast configured to rotate in response to the torque from the drive train, a rotor hub attached to the second end of the mast, a first light transceiver mounted adjacent to the first end of the mast, wherein the first light transceiver is does not rotate relative to the mast, and a second light transceiver mounted adjacent to the second end of the mast, wherein the second light transceiver rotates with the mast.

Abstract: An electric motor adapted to apply torque to a drive shaft rotatable about an axis, the electric motor includes a stator, a rotor adapted to rotate relative to the stator, a primary bearing interoperably coupled to the stator and adapted to provide bearing support between the stator and the rotor, an auxiliary bearing interoperably coupled to the drive shaft, an annular shear adapter connected to the primary bearing and the auxiliary bearing, and a shear pin interoperably coupled to the primary bearing via the annular shear adapter and configured to break responsive to torque between the annular shear adapter and the drive shaft exceeding a predetermined torque threshold.

Abstract: Embodiments are directed to systems and methods for providing light communication (LC) for an aircraft. An LC transmitter is mounted on an aircraft fuselage and is configured to broadcast light signals within a defined region outside the aircraft. An LC receiver mounted on the aircraft fuselage is configured to receive light signals broadcast by a remote LC device. A controller is configured to manage LC signals in the aircraft, and an interface is provided between the controller and an aircraft data network. The light signals may be in a visible light spectrum, an invisible light spectrum, or both. The remote LC device may be, for example, a ground station, an aircraft, a ground vehicle, a ship, a building, or a portable transmitter.
