Title
(EN) TRANSVERSE-AXIS TURBINE WITH TWISTED FOILS
(FR) TURBINE À AXE TRANSVERSAL AVEC BOBINES HÉLICOÏDALES
Abstract
(EN)
A turbine, suitable for use as a water or wind turbine, for generating rotary motion from fluid flow wherein the axis of rotation of the turbine is transverse to the direction of flow. The turbine has two foils, which may meet at the axis of rotation, and the turbine is helical and tapered. The turbine has a quasi-conical base. The non-mount end of the turbine is preferably tilted downstream with the turbine axis of rotation in the range of about 5° to 15° from perpendicular to the flow direction.
(FR)
L'objet de la présente invention concerne une turbine utilisée de préférence comme turbine à eau ou bien à vent, et destinée à créer un mouvement rotatoire à partir d'un flux de fluide lorsque l'axe de rotation de la turbine est transversal par rapport à la direction du flux. La turbine dispose de deux bobines qui peuvent se rejoindre au niveau de l'axe de rotation, et la turbine est hélicoïdale et biseautée. La turbine présente une base quasi-conique. L'extrémité de montage de la turbine est de préférence inclinée vers le bas par rapport à l'axe de rotation, avec une inclinaison comprise entre 5 ° et 15 ° par rapport à la perpendiculaire à la direction du flux.
