rotor wind car avviante to vertical axis, functioning to effect array with many blades formed on each of three aerodynamic profiles

摘要

Self-starting vertical axis wind rotor (11) able to start also at very low wind speeds, for example of the order of 1 m/s, comprising a fixed support structure; a machine for converting the circular movement into electric current, associated with the structure; a vertical shaft rotatably supported by the structure and connected to the machine so that the rotation of the shaft causes the generation of electric current by the machine; a rotatable wind structure connected centrally to the vertical shaft and at the periphery to a plurality of rotor blades; wherein each rotor blade of the plurality of blades comprises three elongated bodies arranged in cascade and having the same wing profile, the elongated bodies being arranged vertical and substantially parallel to each other and to the shaft.
