CA 2671858

There is provided a wind turbine apparatus which comprises blades having an aerofoil profile. The apparatus is arranged to start up even in light wind conditions and to act as a lift type device at higher rotational speeds. The apparatus may comprise wind deflectors to concentrate wind through the apparatus. Further, the blades may be orientated at less than 90° to a radius line which leads to improved performance. Still further, the apparatus may be arranged to heat water by means of solar energy.

L'invention concerne un appareil à turbine éolienne qui comprend des pales ayant un profil aérodynamique. L'appareil est agencé pour démarrer même dans des conditions de vent faible et pour fonctionner comme un dispositif de type à portance à des vitesses de rotation très élevées. L'appareil peut comprendre des déflecteurs d'air afin de concentrer l'air dans l'appareil. En outre, les pales peuvent être orientées à moins de 90° par rapport à une ligne de rayon, ce qui permet d'obtenir une meilleure performance. En outre, l'appareil peut être agencé pour chauffer de l'eau au moyen de l'énergie solaire.
