Title
(EN) HELICAL TURBINE FOR POWER AND PROPULSION SYSTEMS
(FR) TURBINE HELICOIDALE POUR LA PRODUCTION DE COURANT ET POUR LA PROPULSION
Abstract
(EN)
A helical turbine assembly capable of providing high speed unidirectional rotation under a multidirectional ultra low-head fluid flow is disclosed. The assembly comprises an array of helical turbine units (304) arranged vertically or horizontally. Each turbine unit comprises a plurality of helical blades (302) having an airfoil profile. The modules may be mounted to rotatable shafts (322) supported by lightweight structures (316, 324) anchored by gui wires (318, 326) to the ground. The helical turbine (400) can also provide ship (406) propulsion by utilizing the power of ocean waves. In a further embodiment, a cylindrical distributor (206) is provided in the helical turbine to channel the fluid flow to the blades of the turbine. The helical turbine with distributor may be used to lift or lower a body (504) either being submerged into a fast stream or dragged in the fluid. The turbine may also include two or more rings of helical blades (220, 222).
(FR)
L'invention porte sur une turbine hélicoïdale capable d'assurer une vitesse de rotation élevée dans une direction, lorsqu'elle est alimentée avec un fluide à circulation multidirectionnelle et à charge très faible. Le système comprend un ensemble d'unités de turbines hélicoïdales (304) disposées verticalement ou horizontalement. Chaque unité de turbine comprend une pluralité de lames hélicoïdales (302) ayant un profil aérodynamique. Les modules peuvent être montés sur des arbres rotatifs (322) supportés par des structures légères (316, 324) ancrées au sol par des fils d'haubanage (318, 326). La turbine hélicoïdale (400) peut également assurer la propulsion d'un navire (406) en utilisant l'énergie des vagues de la mer. Dans une autre forme d'exécution, un répartiteur cylindrique (206) est disposé dans la turbine hélicoïdale pour canaliser le fluide vers les lames de la turbine. La turbine hélicoïdale avec un répartiteur peut être utilisée pour soulever ou abaisser un corps (504) immergé dans un courant rapide de fluide ou traîné dans un fluide. La turbine peut également comporter deux anneaux de lames hélicoïdales (220, 222) ou davantage.
