Abstract
A wind turbine rotor includes a number of blades (5) which are rotatably mounted about an axis of rotation and a number of blade supports (12) each supporting a respective blade (5). Each blade support includes a pair of legs (14) which are spaced apart along the axis of rotation. A pair of hub supports (62) support the legs (14), with the hub supports (62) also being spaced apart along the axis of rotation. The rotor further includes a pair of bearing systems (52), each bearing system being associated with one of the hub supports (62) and each bearing system rotatably supporting its associated hub support so as to allow its associated hub support to rotate about the axis of rotation. Each hub support allows the communication of forces between the blades (5), and each hub support includes at least a pair of radially extending walls (80).
