Abstract

Les différents modes de réalisation concernent ici un générateur d'énergie éolienne portatif doté d'une turbine éolienne tournant dans un corps cylindrique à tunnel aérodynamique et pouvant générer une puissance de sortie élevée grâce à l'accélération du courant d'air. La surface d'aube de la turbine est partiellement exposée au courant d'air afin d'augmenter le couple des aubes rotatives, ce qui permet d'augmenter la puissance de sortie. Le système de génération d'énergie éolienne utilise une pression de vent élevée générée par le déplacement rapide de véhicules par la canalisation du vent induit dans la direction de la turbine éolienne. Le système est installé le long d'une ligne de séparation de trafic située au milieu d'une chaussée. Le système comprend une turbine éolienne rotative pouvant générer une puissance de sortie élevée grâce à l'accélération d'un courant d'air et un ensemble de conduites d'air agencées à l'opposé les unes des autres pour canaliser un courant d'air.
