Abstract

Eolienne à axe horizontal caractérisée par l'utilisation d'un rotor innovant (7) qui permet d'atteindre un rapport puissance sur volume plus élevée que celui des éoliennes classiques à axe horizontal à une seule rangée de pales. Le rotor innovant est constitué de deux rangées de pales, une première rangée immobile (1) et une seconde rangée tournante (2). La superposition de pales de la première rangée génère une série de buses (5) de sections transversales appropriées qui accélèrent l'écoulement d'air, lequel heurte les pales de la seconde rangée à un angle optimal amenant l'arbre de commande (6) à tourner. En outre, l'énergie ainsi produite est transférée de façon classique au générateur par le biais d'une boîte de vitesse.
