Abstract: The wind turbine (1) includes a tower (2) supporting a main boom (3) carrying a rotor (4) of the axial flow type having a main rotation axis and including a hub (5) carrying a number of blades (6) being supported by blade lines (7, 8). A pitch angle of each blade about its pitch axis is controllable by coordinated movement of a set of at least a first displace-able pitch control cable (10) and a second displaceable pitch control cable (11) acting on said blade. Each pitch control cable has a blade end (12) being attached to the respective blade at a longitudinal position more than ? of the total blade length away from the main rotation axis and has a boom end (13) being attached to a pitch control mem-ber (14) arranged rotatably on the main boom and being adapted to displace the pitch control cable.
