Title
(EN) HELICAL WIND TURBINE
(FR) EOLIENNE HELICOIDALE
Abstract
(EN)
A vertical axis wind turbine wherein the blades of the rotor section of the wind turbine comprise at least sections wherein the blades have a non-linear configuration in the 'z' axis. In a preferred embodiment, the blades of the rotor section have a linear trailing edge with a non-linear, and preferably helical, surface configuration. This particular design allows the blades to provide both a rotational force and a positive or negative lift component. Further, the blades define an open area in the center of the rotor section through which air flow can pass in order to create a vertical vortex of air. As such, a more efficient vertical axis wind turbine provided.
(FR)
L'invention concerne une éolienne à axe vertical dont les aubes de la section rotor comprennent au moins des sections présentant une configuration non linéaire dans l'axe z. Dans un mode de réalisation préféré, les aubes de la section rotor possèdent un bord de fuite linéaire qui présente une surface non linéaire, et de préférence hélicoïdale. Cette conception spécifique permet aux aubes de produire une force de rotation et une composante de portance positive ou négative. En outre, les aubes définissent une zone ouverte dans le centre de la section rotor à travers laquelle un flux d'air peut passer afin que soit créé un vortex d'air vertical. L'invention permet d'obtenir une éolienne à axe vertical plus efficace.
