Title
(EN) CONSTRUCTIVE DYNAMIC INTERACTION BETWEEN ENERGY KITE AND FLOATING PLATFORM
(FR) INTERACTION DYNAMIQUE CONSTRUCTIVE ENTRE UN CERF-VOLANT ÉNERGÉTIQUE ET UNE PLATE-FORME FLOTTANTE
Abstract
(EN)
An example method includes: determining a period of natural oscillation of a floating ground station in an airborne wind turbine with an aerial vehicle coupled to the ground station via a tether, and wherein each natural-oscillation period comprises forward and backward displacement of the floating ground station with respect to the aerial vehicle; and operating the aerial vehicle to fly in a substantially circular path with a looping period that matches the natural-oscillation period of the floating ground station, and 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 the circular path corresponds to forward displacement of the floating ground station, and movement of the aerial vehicle on an upstroke portion the circular path corresponds to reverse displacement of the floating ground station.

Un procédé illustratif consiste à : déterminer une période d'oscillation naturelle d'une station au sol flottante dans une éolienne aéroportée avec un véhicule aérien accouplé à la station au sol par l'intermédiaire d'une amarre, chaque période d'oscillation naturelle comprenant un déplacement vers l'avant et vers l'arrière de la station au sol flottante par rapport au véhicule aérien ; et faire fonctionner le véhicule aérien pour qu'il vole selon un trajet sensiblement circulaire avec une période de boucle qui correspond à la période d'oscillation naturelle de la station au sol flottante, et une phase de boucle qui s'aligne avec la phase d'oscillation de la station au sol flottante de telle sorte que le mouvement du véhicule aérien sur une partie de course descendante du trajet circulaire corresponde à un déplacement vers l'avant de la station au sol flottante, et que le déplacement du véhicule aérien sur une partie de course montante du trajet circulaire corresponde au déplacement inverse de la station au sol flottante.
