An energy extraction device for extracting energy from a flow of fluid is provided. The energy extraction device comprises a rotating member for rotatably mounting to a support structure, at least one rotatable bank of blades connected to the rotating member through a connection disposed radially from the main axis of rotation of the rotating member, and, a pitch control system for controlling the angular position of the at least one rotatable bank of blades relative to a direction of the flow of fluid. The rotating member has a main axis of rotation and the at least one bank of blades comprises an array of spaced-apart blades secured together. Each of the at least one bank of blades has a bank axis of rotation.

L'invention porte sur un dispositif d'extraction d'énergie destiné à extraire de l'énergie d'un écoulement de fluide. Le dispositif d'extraction d'énergie comprend un élément rotatif prévu pour un montage rotatif sur une structure de support, au moins un ensemble rotatif d'aubes relié à l'élément rotatif par l'intermédiaire d'une liaison disposée radialement depuis l'axe de rotation principal de l'élément rotatif, et un système de commande de pas servant à commander la position angulaire de l'ensemble rotatif d'aubes par rapport à un sens de l'écoulement de fluide. L'élément rotatif a un axe de rotation principal et l'ensemble d'aubes comprend un groupe d'aubes espacées fixées les unes aux autres. Chacun des ensemble d'aubes a un axe de rotation.
