The inventive wind-driven powerplant comprises an inlet ring-shaped casing and an external annular casing, the inner surface of which has a circular cross-section. A turbine is coaxially arranged inside the annular casing. A mechanical energy converting mechanism is kinematically coupled to the turbine. At least one part of the external casing has an elliptical cross-section. The longer axis of the ellipse, which determines the shape of the cross- section of the outer surface of the inlet casing at the input thereof, is not less than 0.55 and not greater than 0.95 of the diameter of a circle determining the shape of the inner surface of the external casing at the smallest cross-section thereof.
L'invention concerne une installation éolienne qui comprend une enveloppe de forme annulaire et une enveloppe annulaire externe avec, à l'intérieur, une coupe transversale de forme circulaire. A l'intérieur de l'enveloppe annulaire on a monté coaxialement une turbine. Un mécanisme est relié cinématiquement à la turbine, qui sert transformer l'énergie cinétique. Au moins une partie de l'enveloppe extérieure a en coupe transversale la forme d'une ellipse. Le grand axe de l'ellipse qui détermine la forme de section transversale de la surface externe de l'enveloppe d'entrée à l'entrée de cette dernière correspond entre au moins 0,55 et au plus 0,95 du diamètre du cercle qui détermine la forme de la surface interne de l'enveloppe externe dans sa section minimale.
