Abstract

L'invention concerne l'énergie éolienne. Une éolienne à axe de rotation vertical comprend un rotor creux dont les pales sont fixées à un arbre, l'éolienne comprenant également un mécanisme d'entraînement. Le rotor se présente sous une forme tronconique et est placé au centre d'une armature pyramidale. Les pales sont réalisées sous la forme d'un triangle rectangle à angles aigus tronconiques et sont cintrées selon une développante. Les pales sont également fixées à un disque horizontal qui sert de volant d'inertie et de plaque support du rotor. Selon un premier mode de réalisation, le disque et la couronne de support sur laquelle il est monté sont placés sur une plate-forme formée par les supports inférieurs de l'armature. Selon un deuxième mode de réalisation, le rotor est disposé sur une tige au centre de l'armature pyramidale. Dans ce cas, le disque précité est monté sur la tige qui est équipée d'une butée. Cette invention permet de produire une structure modulaire dont les composants peuvent être remplacés facilement tout en augmentant le rendement d'utilisation de l'écoulement de l'air.
