  • the upper rotor 22 may be separated from the lower rotor 23 by a mechanism arranged to lift the upper rotor, so producing a gap of between the two rotors.
  • Figure 18A diagrammatically shows the driving of the turbine when in its normal condition with the two rotors immediately adjacent to each other and in alignment.
  • Figure 18B shows the upper and lower rotors separated; as can be seen, there is a clear path 48 for air between the upper and lower rotors.
  • airflow through the rotors air is also encouraged to flow through the V-shaped space between the rotors into the path 48, so largely removing the airflow of arrows 2 ( Figures 13 and 14) which otherwise would add to the drive.

Abstract

L'invention concerne un rotor (22, 23) destiné à une éolienne à axe vertical, comprenant une pluralité de sections identiques comportant chacune une paire d'aubes (24) disposées en V avec des bords d'attaque (26) communs. Chaque section comporte également une paire de panneaux convergents (25) en V disposés dans la paire d'aubes (24) et associés de manière à former avec ces dernières un espace en V. L'aire transversale de l'espace en V se réduit vers l'intérieur du rotor (22, 23). Ainsi, lorsque l'air vient frapper cette zone, il pénètre dans l'espace en V à partir de la périphérie d'une section. L'air est accéléré dans l'espace et quitte la sortie intérieure pour venir frapper les aubes (24) de la section suivante par rapport à la direction de rotation du rotor pour extraire davantage d'énergie du vent incident. Le rotor peut comprendre deux sous-rotors (22, 23) et être ralenti par déplacement relatif angulaire ou axial des rotors supérieur et inférieur.
