Abstract

L’invention concerne la production d’énergie éolienne. L’installation éolienne de l’invention comprend une roue éolienne et une génératrice, montées sur un même arbre et disposées à l’intérieur d’une conduite d’air verticale. Dans sa partie inférieure, la conduite comporte un segment de sortie. Dans sa partie supérieure, la conduite comporte un segment d’entrée monté au moyen d’un raccord articulé; le plan d’ouverture de ce segment n’est pas horizontal, et sa superficie d’ouverture est égale ou supérieure à la section transversale de la conduite. Le segment d’entrée est muni du côté opposé à l’ouverture de portières de dérivation d’air actionnées par ressort. Le segment d’entrée est doté d’un gouvernail. La roue éolienne est dotée d’un carénage avant. A l’avant de la roue éolienne on a monté un système de commande de la couche limite qui se présente comme une fente ouverte sur l’extérieur dans la paroi latérale de la conduite et qui est protégée par un déflecteur sur la surface extérieure de la conduite du côté vers lequel est tournée l’ouverture du segment d’entrée. Le déflecteur est monté dans le segment d’entrée et comporte sur ses bords latéraux des orifices d’éjection orientés du côté opposé au sens d’ouverture du segment d’entrée. L’invention permet d’assurer la commande de la couche limite compte tenu de la direction du vent et d’une meilleure efficacité de l’installation éolienne.
