    Abstract: Wind energy systems, such as an Airborne Wind Turbine (“AWT”), may be used to facilitate conversion of kinetic energy to electrical energy. An AWT may include an aerial vehicle that flies in a path to convert kinetic wind energy to electrical energy. The aerial vehicle may be tethered to a ground station with a tether that terminates at a tether termination mount system. In one aspect, the tether termination mount system may include a tether termination unit configured in one or more gimbals that allow for the tether termination unit to rotate about one or more axes while tracking the aerial vehicle in flight. In a further aspect, the tether termination mount system may include an imaging device configured for imaging the aerial vehicle during flight in order to enhance tracking accuracy over that which is performed by angular motion of the tether termination unit.

    Abstract: Exemplary embodiments disclosed herein include bearings with three races: an inner race, a shared race, and an outer race that exhibit increased life under oscillatory loads. The exemplary embodiments may include one or more directional biasing mechanisms configured such that when a bearing shaft rotates in one direction, the shared race rotates with it, and when the shaft oscillates in the other direction, the shared race is impeded from moving in the other direction. Under continued oscillation, the shared race will “walk” in circles around the shaft, effectively distributing the load and wear over the entire circumference of a bearing surface.

    Abstract: Wind energy systems, such as an Airborne Wind Turbine (“AWT”), may be used to facilitate conversion of kinetic energy to electrical energy. An AWT may include an aerial vehicle that flies in a path to convert kinetic wind energy to electrical energy. The aerial vehicle may be tethered to a ground station with a tether that terminates at a tether termination mount. In one aspect, the tether may be a conductive tether that can transmit electricity and/or electrical signals back and forth between the aerial vehicle and the ground station. The tether termination mount may include one or more gimbals that allow for the tether termination mount to rotate about one or more axis. In a further aspect, the tether termination mount may include a slip ring that allows for rotation of the tether without twisting the tether.

    Abstract: Wind energy systems, such as an Airborne Wind Turbine (“AWT”), may be used to facilitate conversion of kinetic energy to electrical energy. An AWT may include an aerial vehicle that flies in a path, such as a substantially circular path, to convert kinetic wind energy to electrical energy. The aerial vehicle may be coupled to a winch assembly via a tether. The winch assembly may include a winch drum and a drum door. The winch assembly may be configured such that the drum door may operate in two or more positions, such as an open position and a closed position, to reduce the likelihood of stability problems occurring at the aerial vehicle during winding or unwinding of the tether.
