Abstract

L'invention concerne un convertisseur d'énergie éolienne comportant plusieurs rotors de Savonius qui sont agencés en une rangée parallèlement les uns à côté des autres et qui comportent chacun deux ailes en forme de pale se chevauchant l'une l'autre fixées le long de l'axe de rotation du rotor et formant entre elles un canal central de passage du vent. Les axes de rotation des rotors sont reliés les uns aux autres par une transmission de telle manière qu'un rotor sur deux tourne dans le même sens et que chaque rotor se trouvant entre eux tourne dans le sens opposé, l'espace de déplacement des ailes du rotor perpendiculaire à l'axe de rotation et parcouru par les deux ailes du rotor traversant en partie l'espace de déplacement des ailes du rotor adjacent, et que, lorsqu'un rotor est dans la position transversale, dans laquelle les deux ailes du rotor se trouvent sensiblement dans l'alignement de la rangée de rotors, les extrémités extérieures des ailes du rotor sont rapprochées des ailes des rotors adjacents transversales à ces dernières de telle manière que les ailes de tous les rotors forment une rangée fermée, en particulier une paroi, l'air ne s'écoulant alors pratiquement plus que par les canaux de passage du vent.
