Abstract

La présente invention concerne une éolienne à pales composées et disposées de telle façon que l'admission de la force du vent soit en même temps frontale et périphérique. Le principe de la pale composée, constituée de plusieurs pales secondaires disposées sur des plans successifs associé au principe de la convergence permet d'atteindre des rendements supérieurs et sans commune mesure avec les rendements des éoliennes classiques à l'heure actuelle, puisqu'on obtient des puissances supérieures même avec des diamètres plus réduits. Ce genre de machine est particulièrement adapté aux éoliennes de grande puissance concernant la production électrique.
