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