Abstract: The present invention preferably relates to a joined blade rotor system having substantially a horizontal axis for a wind turbine including a number of joined blade assemblies extending substantially radially from a central hub wherein each joined blade assembly includes a first blade and a second blade or more blades in different planes that are connected by one or more brace systems to each other. Each central hub includes an operating member to effect pitch rotation of the joined blade assembly or directly the first blade pitch rotation and the second blade pitch rotation about the respective blade axis. A bearing provides a relative rotation between the first or second blade and brace strut while pitch angles change.
