VERTICAL AXIS WIND TURBINE ROTOR

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.

1. Vertical axis wind turbine rotor (11) comprising a plurality of parallel rotor blades (13) arranged along the generatrices of a vertical cylinder and connected by means of a radial-arm structure (15) to a central shaft (17) passing along the axis of the cylinder, said shaft (17) being able to be associated with a machine (21) for converting the movement into electric energy, characterized in that each rotor blade (13) of said plurality of blades comprises three elongated bodies (25) arranged in cascade and having the same wing profile, said elongated bodies being arranged vertical and parallel to each other and to the central shaft (17).
