Patent abstract

A complete fully-automated airborne wind energy generation system with three major components; a ground-based energy trailer anchored to the ground containing a reel, motor/generator, motor controller with regenerative braking, a low-friction capstan, and a microcontroller; an ‘aerie’ elevated launch and landing platform free to weathervane in the wind, with a tether flag deployment and collection device; a statically and dynamically stable rotor-glider with variable pitch rotor blades enabling jump-launch, on-board weather and load sensors, microcontroller, and cell or satellite phone data connections to a centralized database; and a high-strength low-weight tether connecting all the components together.
