Abstract
(EN)
Wing-tip device for the tip of a wing or the blade of a wind generator or of a marine generator that makes it possible to reduce or even cancel what are known as wing-tip vortices. In the case of a wind generator, the result provides a start-up with less wind, control and energy efficiency that are highly productive throughout its use while at the same time significantly reducing the noise caused by the vortex.

(FR)
Dispositif d'extrémité d'aile ou de pale d'éolienne ou d' hydrolienne permettant de diminuer voire annuler les tourbillons marginaux dits vortex. Dans le cas d'une éolienne le résultat donne un démarrage avec moins de vent, une régulation et un rendement énergétique très productifs pendant toute son utilisation tout en diminuant significativement le bruit provoqué par le vortex.
