ABSTRACT:
A rotor blade of a wind power plant, comprising a rotor blade connection for connection to a hub of the rotor of a wind power plant and a blade tip disposed at the opposite end of the rotor blade. In order to provide a rotor blade in which flexing can be detected with simple means, at least one electrical conductor is laid over the length of the rotor blade, wherein the electrical conductor begins at the rotor blade connection, extends in the longitudinal direction of the rotor blade and back to the rotor blade connection, and that there is provided a detector which detects the electrical resistance of the conductor and is connected to an evaluation device which evaluates the electrical resistance.
