Abstract: Methods and systems described herein relate to power generation control for an aerial vehicle of an air wind turbine (AWT). More specifically, the methods described herein relate to balancing power generation or preventing a component of the aerial vehicle from overheating using rotor speed control. An example method may include operating an aerial vehicle in a crosswind-flight mode to generate power. The aerial vehicle may include a rotor configured to help generate the power. While the aerial vehicle is in the crosswind-flight mode the method may include comparing a power output level of the aerial vehicle to a power threshold and, based on the comparison, adjusting operation of the rotor in a manner that generates an optimal amount of power or minimizes overheating of the aerial vehicle.

Abstract: Methods and systems described herein relate to power generation control for an aerial vehicle. An example method may include operating an aerial vehicle in a crosswind-flight orientation substantially along a first flight path to generate power. The first flight path may include a substantially circular path that allows the aerial vehicle to generate the power. While the aerial vehicle is in the crosswind-flight orientation the method may include determining to reduce the power being generated by the aerial vehicle, and responsive to the determination, determining a second flight path that will reduce the power generated by the aerial vehicle when operating on the second flight path. Once determined, the aerial vehicle may operate substantially along the second flight path.

Abstract: A method may involve operating an aerial vehicle to travel along a first closed path on a tether sphere while oriented in a crosswind-flight orientation. A tether may be connected to the aerial vehicle on a first end and may be connected to a ground station on a second end. Further, the tether sphere may have a radius corresponding to a length of the tether. The method may further involve while the aerial vehicle is in the crosswind-flight orientation, operating the aerial vehicle to travel along a second closed path on the tether sphere, such that a speed of the aerial vehicle is reduced. And the method may involve after or while the speed of the aerial vehicle is reduced, transitioning the aerial vehicle from traveling along the second closed path while in the crosswind-flight orientation to a hover-flight orientation.

Abstract: A system may include a tether connected to a ground station. The tether may include at least two bridle segments. The system may further include an aerial vehicle connected to the at least two bridle segments. The system may also include at least one sensor and a control system. The control system may be configured to: a) receive sensor data from the at least one sensor; and b) determine a tether roll angle based on the sensor data. The tether roll angle may represent an angle between the tether and an axis of the aerial vehicle. Optionally, the control system may also be configured to determine a curvature of a path of the aerial vehicle based on the tether roll angle. The control system may additionally be configured to control at least one control surface of the aerial vehicle based on the curvature of the path.
