Abstract
In order to optimise a rotor (1) for a wind turbine (2), comprising a hub (6) which is rotatable about an axis of rotation (15) and a number of rotor blades fixed to the hub (6), at least one rotor blade having at least one curved portion (8) having a curve in the upstream direction, so as to increase the performance of wind turbines (2), it is proposed for a base portion (7) of the curved rotor blade (5), extending from the hub end, to be arranged with the longitudinal axis (14) thereof at a wind correction angle (11) in the upstream direction to a plane (16) orthogonal to the axis of rotation (15).
