The invention relates to a vertical-axis wind turbine and at least 2 turbine blades, wherein every turbine blade is connected via a supporting arm and a connecting element that can be purely tensile-loaded to the rotatable vertical axis. According to the invention, between the connecting element that can be purely tensile-loaded and the supporting arm a blade is provided that is convex at an angle of attack side defined by the turbine blades and is concave at the other side. The invention also relates to a method for manufacturing a wind turbine.
L'invention concerne une éolienne à axe vertical qui comprend au moins deux pales, chaque pale étant raccordée par l'intermédiaire d'un bras de support et d'un élément de raccordement sollicité par traction et raccordé à l'axe vertical rotatif. Selon l'invention, une pale de forme convexe sur un côté angle d'attaque défini par les pales et de forme concave sur l'autre côté est disposée entre l'élément de raccordement pouvant être sollicité par traction et le bras de support. L'invention concerne également un procédé de fabrication d'une éolienne.
