Joined Blade Wind Turbine Rotor

摘要

The present invention preferably relates to a joined blade rotor system having substantially a horizontal axis for a wind turbine comprising a number of joined blade assemblies extending substantially radially from a central hub wherein each joined blade assembly comprises 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 comprising operating means to effect pitch rotation of the said joined blade assembly or directly the first blade pitch rotation and the second blade pitch rotation about the respective blade axis. Bearing provides a relative rotation between the said first or second blade and brace strut while pitch angles change.
