The wind generating device of the present invention employs modules each having two turbines. Each of the turbines employs two rotors, coaxially aligned and arranged one downstream from the other. The arrangement includes a proximal channel with a leading portion having decreasing radius toward the first rotor which acts as a collector and a following portion connecting fluidly the first and second rotor and a distal channel which is separate from the proximal channel and opens into the following portion thereby adding to the airflow to the second rotor. Downstream from the second rotor is a diffuser with radius increasing with distance from the rotor. The invention includes means for mounting modules vertically stacked which allows for yaw responsive to wind. The device further includes means to mount the modules on a tower.

La présente invention concerne un aérogénérateur utilisant des modules, chacun pourvus de deux turbines. Chacune des turbines utilise deux rotors, alignés coaxialement et placés l'un en aval de l'autre. Cet ensemble présente un canal proximal, pourvu d'une section avant, présentant un rayon décroissant vers le premier rotor agissant comme un collecteur, et d'une section suivante établissant une liaison fluidique entre les premier et second rotors, ainsi qu'un canal distal séparé du canal proximal et débouchant dans la section suivante, ajoutant ainsi un débit d'air vers le second rotor. En aval du second rotor se trouve un diffuseur dont le rayon augmente en s'éloignant du rotor. Cette invention comprend également des moyens servant à fixer des modules de manière empilée verticalement, permettant ainsi un mouvement de lacet sous l'effet du vent. Ledit aérogénérateur comporte en outre des moyens servant à fixer ces modules sur une tour.
