  • Wind energy conversion systems, devices, and methods
    Patent number: 9643721
    Abstract: Airborne devices for generating power in a crosswind power generating phase, including a body and at least one non-planar wing. A control system directs the airborne device to follow a predetermined flight path of increasing altitude during the crosswind power generating phase. Wind energy conversion systems and methods including an airborne device, a tether, a generator, and a control system that directs the airborne device to follow a predetermined flight path including a crosswind power generating phase.
    Type: Grant

  • AIRBORNE WIND ENERGY CONVERSION SYSTEMS, DEVICES, AND METHODS
    Publication number: 20150097086
    Abstract: Wind energy conversion systems including an airborne wing, a tether, a generator, and a control system arranged to communicate with the airborne wing so that the control system directs the airborne wing to follow a predetermined flight path including a power generating phase. The predetermined flight path, during the power generating phase, includes a crosswind flight path of increasing altitude and a plurality of airborne wing turns, at each turn the airborne wing turn around an axis of the airborne wing, so that a vertical airspace for the predetermined flight path during the power generating phase is minimized.
