Abstract

L'invention porte sur une éolienne comprenant une couronne de canaux de flux (2) qui entoure en anneau une cheminée à flux ascendant (1) et des turbines éoliennes (5) qui sont montées dans les canaux de flux (2) et qui présentent un rotor de turbine dont l'axe s'étend perpendiculairement à la direction du souffle du vent, une protection composée d'organes directeurs (8) étant associée aux rotors de turbine (6) dans la région de leur côté circonférentiel qui tourne en sens inverse de la direction du souffle du vent. L'invention vise à créer des conditions de construction avantageuses. A cet effet, les canaux de flux (2) s'étendent entre des parois de soutien (3) qui sont orientées radialement par rapport à la cheminée à flux ascendant (1) et qui portent un support annulaire (4) pour la cheminée à flux ascendant (1), et les organes directeurs (8) comprennent des parois directrices (9) montées pour pouvoir pivoter autour d'un axe de pivotement (10 parallèle à l'axe du rotor de turbine (6) entre une position de départ (a) qui dégage la voie de flux et une position finale (b) qui ferme la voie de flux.
