摘要： 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 via a tether that terminates at a tether termination mount. In one aspect, the ground station may have a motor that may be used, for example, as a winch motor to turn the drum to assist in deployment and/or refraction of the tether and AWT. It may be desirable to be able to switch from an engaged and disengaged condition of the motor. For example, it may be desirable to disengage the motor to help reduce wear on the drivetrain and/or to help reduce loads on the drivetrain.

摘要： An example method may include receiving data representing an initial position and an initial attitude of an aircraft. The method further includes determining a change to a first attribute and a second attribute of the position or the attitude of the aircraft to achieve a subsequent position and a subsequent attitude. The method also includes determining a priority sequence for changing the first attribute and the second attribute of the position or the attitude of the aircraft based on a first thrust of the actuator to achieve the change to the first attribute and a second thrust of the actuator to achieve the change to the second attribute. The priority sequence is configured to cause changes to the first attribute before causing changes to the second attribute where the actuator is unable to concurrently provide the first thrust and the second thrust.

摘要： 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. In an example embodiment, the aerial vehicle may be connected to a ground station via a tether that both restrains the AWT and conveys the electrical energy to the base station. The tether may be wound about a drum when the AWT is not in flight, and the drum may include a helical groove of varying pitch to receive the tether. An asymmetrical levelwind may be positioned adjacent to the drum and configured to move along the drum and guide the tether onto the drum.

摘要： 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.
