Definitions

  • the angle of attack of the aerofoils may be increased which has been found to change and increase the associated lift force provided by the wind passing the aerofoil.
  • the coefficient of lift increases almost linearly with the angle of attack up to around 8 to 18 degrees and preferably 10 to 16 degrees.
  • the drag, " however, remains almost negligible for angles of attack less than 10 degrees. Therefore according to one embodiment it is preferable to have a large enough angle of attack without significant increase in drag.
  • the aerofoil is able to pivot freely between a positive angle of attack in an upwind position on the two endless support means and a negative angle of attach in a downwind position on the two endless support means under the influence of the wind and/or gravity only and without the influence of another active mechanical mechanism.
  • the wind energy apparatus as herein described provides an arrangement that is significantly more simplified than current designs of linear wind energy conversion arrangements.

Abstract

L'invention porte sur un appareil de conversion de l'énergie éolienne qui comprend : un châssis support ; une paire supérieure d'éléments rotatifs espacés axialement, placés dans une partie supérieure du châssis support ; une paire inférieure d'éléments rotatifs espacés axialement placés dans une partie inférieure du châssis support, les paires supérieure et inférieure d'éléments rotatifs espacés axialement étant sensiblement dans un alignement vertical ; deux moyens de support sans fin, montés chacun autour des éléments rotatifs supérieurs et inférieurs alignés verticalement et configurés pour se déplacer dans un mouvement de circulation, ce par quoi le mouvement des moyens de support sans fin fait tourner les éléments rotatifs supérieurs et inférieurs ; et une pluralité de plans aérodynamiques accouplés entre les deux moyens de support sans fin, chaque plan aérodynamique étant accouplé entre les deux supports sans fin à des extrémités opposées du plan aérodynamique dans une position au droit ou en avant du centre de gravité du plan aérodynamique. Le vent qui passe à travers la pluralité des plans aérodynamiques produit une force de translation sur le plan aérodynamique qui, à son tour, entraîne le mouvement des deux moyens de support sans fin et par conséquent la rotation des éléments rotatifs supérieurs et inférieurs.
