Abstract:
The invention relates to a process for manufacturing a blade connection of a rotor blade for a wind energy system which comprises fastening elements for fastening the blade connection to a hub, which fastening elements are provided on a circular arc, preferably equidistant from each other. Furthermore, the invention relates to a blade connection and a fastening element for a blade connection. The invention is based on the problem of improving the fastening of a rotor blade on the hub of a wind energy system as well as improving the manufacture and/or making a suitable blade connection available. The invention solves this problem as regards the process in that fastening elements formed in pieces are arranged on the circular arc and spaced from each other with spacer elements.
