Abstract

The invention relates to a rotor for a wind turbine, which wind turbine comprises: a support construction, for instance a post, a column or a spatial tube construction; and a generator supported by this support construction and having an outward protruding horizontal shaft which is rotatably mounted and carries a generator rotor forming part of the generator; which rotor comprises the following rotor parts: a hub with first coupling means for releasable rigid coupling of the hub in coaxial relation to the end of the shaft; and a number of blades which are coupled rigidly and releasably to the hub by means of respective second coupling means via the ends of their respective blade roots; wherein the hub and each blade root consist of composite material.
