<p>A vertical axis wind turbine generator is disclosed, comprising a rotor (1) having at least two rotor vanes (3, 4) reaching from an upper rotor disc (5) to a lower rotor disc (6) defining a rotor periphery (PE), the rotor vanes extending in parallel disposition displaced from the rotor centre for rotation about their common axis of rotation (C). Each rotor vane (3,4) comprises a leading rotor vane segment (3a, 4a) connecting at an angle to a trailing rotor vane segment (3b, 4b), the connection forming a knee (3c, 4c) which reaches from the upper rotor disc to the lower rotor disc at a radial distance from the axis of rotation. A stator arranged about the rotor comprises at least four stator vanes (8) equidistantly spaced about the periphery of the rotor (1) and oriented substantially in tangential direction to the rotor periphery, wherein the leading rotor vane segment (3a, 4a) and the trailing rotor vane segment (4a, 4b) each has a sectional profile which is curved forward in the direction of rotation from the knee connection (3c, 4c) to a peripheral end(3d, 3e, 15 4d, 4e) at the rotor periphery, the peripheral ends connecting to the rotor periphery at a circumferential distance between the peripheral ends substantially corresponding to the circumferential length of the rotor periphery between the stator vanes.</p> |
