Abstract

The invention relates to the fastening of rotor blades to the rotor hub of wind turbines using transverse pins and tension rods in the region of the blade root. The transverse pins are arranged throughout the entire blade root shell wall and can be connected to a flange of the hub by the tension rods in the form of expansion screws. Each transverse pin (4) can be connected to the flange (2) of the rotor hub (1) by two tension rods (5, 6). Each tension rod (5, 6) is arranged in a separate tension rod bore (7, 8) in the blade root shell wall (3).
