Definitions

  • a wind turbine multi-panel blade with an aerodynamic profile made up by at least a lower shell on the pressure side and an upper shell on the suction side and two prefabricated inner crossbeams.
  • These lower and upper shells are assembled to these inner crossbeams, in which these lower and upper shells and these prefabricated inner crossbeams include, respectively, some extensions configured in such a way that they can be assembled making up the blade's root.
