Abstract: Primary blade modules for a wind turbine blade are provided comprising a first blade shell, two opposed spar caps, and at least one shear web. The first blade shell has a root end and a first coupling end configured to be coupled with a secondary blade module. The two opposed spar caps have respective first spar cap portions extending along the first blade shell substantially from the root end to the first coupling end of the first blade shell, and respective second spar cap portions extending beyond the first coupling end. The at least one shear web extends between the opposed spar caps at least partially along the respective first spar cap portions. Secondary blade modules, systems for transporting primary blade modules, and methods of assembling (in situ) wind turbine blades having a primary blade module and a secondary blade module are also provided in the present disclosure.

Abstract: A blade for a wind turbine comprising a blade root portion is described. The blade root portion defines a mounting surface for coupling to a hub or extender of the wind turbine and comprises a plurality of first holes provided with an insert, the blade root portion further comprises a mounting flange arranged in the periphery of the mounting surface and provided with second holes, wherein the inserts comprise a first end embedded in the blade root portion and a second end opposite to the first end, the second end protruding beyond the mounting surface of the blade root portion, and wherein the second ends are fitted in the second holes of the mounting flange and the mounting flange is attached to the blade by means of the inserts. Furthermore, a wind turbine rotor comprising such a blade is described. Methods of manufacturing half a wind turbine blade and a whole wind turbine blade are also described.
