Title
(EN) Use of Wave Energy by Energy Kite and Floating Platform
Abstract
(EN)

An example method includes: determining wave data corresponding to a floating ground station of an airborne wind turbine, wherein an aerial vehicle is coupled to the floating ground station via a tether; determining, based on the wave data, an oscillation profile of the floating ground station; and operating the aerial vehicle to fly in a closed path with: (a) a looping period that matches the period of wave-influenced oscillation of the floating ground station, and (b) a looping phase that aligns with the oscillation phase of the floating ground station such that movement of the aerial vehicle on a downstroke portion of the closed path corresponds to forward displacement of the floating ground station, and movement of the aerial vehicle on an upstroke portion the closed path corresponds to reverse displacement of the floating ground station.
