Abstract
A vertical axis wind turbine comprising: a plurality of support arms (2) connected with a vertical axis (1), a wind rotor comprising a plurality of blades (3) connected to the blade support arms (2), the wind rotor having a rotation radius and the blades (3) having a chord length; wherein an airfoil of the blade is an asymmetrical camber airfoil, the convex surface (31) of the blade (3) faces vertical axis (1), and a ratio of the rotation radius of the wind rotor (R) to the chord length of the blade (L) is between about 1.8 and about 4.
