Abstract

Éoliennes à axe vertical qui comprennent des ailes (pales) de rotor (1) d'éolienne avec tous leurs segments aérodynamiques correspondant aux numéros 1a, 1b, 1c, 1d, 1e, 1f et 1g, et des ailes de support. Cette éolienne représente un nouveau type d'éolienne à axe vertical pour produire de l'électricité. La principale innovation de cette éolienne, en comparaison à d'autres éolienne à axe vertical, concerne les ailes (pales) de rotor d'éolienne et les ailes de support. Ladite éolienne comporte trois ailes (pales) présentant une forme aérodynamique et légèrement incurvée du bord inférieur au bord supérieur de l'aile. La largeur de l'aile diminue vers la partie supérieure. Chaque aile comporte deux supports. Le support inférieur est plus étendu, et le support supérieur est plus court et situé à un certain angle de rotation par rapport au support inférieur (à un niveau différent), les trois ailes formant dans la partie supérieure un diamètre plus petit par rapport à la partie inférieure du rotor. De cette manière, les ailes (pales) de rotor d'éolienne selon l'invention surmontent plus facilement la résistance à l'air dans leur axe de mouvement, et ne font pas de bruit. L'éolienne selon l'invention de conception simple, économique et silencieuse représente une toute nouvelle solution dans le domaine des éoliennes. Lesdites éoliennes sont idéales pour de larges applications et sont particulièrement adaptées aux zones urbaines. La stabilité statique, le générateur, le rotor et la conception globale desdites éoliennes représentent une idée totalement nouvelle en matière de brevets dans le domaine des énergies renouvelables.
