Abstract

Le problème à résoudre dans le cadre de la présente invention est de prévoir une éolienne utilisant la composante de traînée qui tourne de façon efficace même si le vent est faible et réduit le bruit entraîné par le vent à l’arrière des pales de celle-ci. La solution proposée réside en ce que les pales (3) de l’éolienne de type Savonius utilisant la composante de traînée sont formées de tôle mince d’alliage d’aluminium, et un nombre important d’embossages sphériques (6) sont formés sur les pales (3) par une presse afin d’être évidés sur le côté avant de celles-ci recevant le vent et en saillie sur le côté arrière de celles-ci pour augmenter la traînée des pales (3) recevant le vent par l'intermédiaire des formes évidées des embossages (6) sur le côté avant de sorte que les pales puissent être tournées de façon efficace même si le vent est faible et que le bruit entraîné par le vent sur le côté arrière des pales (3) puisse être réduit par les évidements et saillies formés entre les formes en saillie des embossages (6) sur le côté arrière et les autres parties.
