Abstract:
An eolian systems for energy production of the type consisting of several blades (1) mounted in a vertical position to a flexible, closed transmission belt consisting of a support structure based on towers or columns (3) defining the geometry of the transmission belt, whose towers or columns (3) support pulleys (4 or 19) over which run cables to which the blades (1) are fixed, being characterized in that they include a mechanism permitting the controlled variation of the angle between the blades (1) and the transmission belt to obtain the maximum performance when the wind is advantageous, such that each blade (1) is joined by its head or attack edge to the so-called drag lines (2), across separators (6) consisting of rods articulated to the blade (1) or the line (2), such that, at its tail or exit edge, the blades (1) are joined to ruling cables (8), such that the latter may be displaced longitudinally by the pulleys (4') braking supporting them, or transversely by displacement of the mentioned pulleys (4') in a horizontal plane and, as a result, vary the blade (1) angle with respect to the wind.
