Beschreibung
Zusammenfassung:	A system for detecting the deflection of a rotor blade coupled to a hub of a wind turbine rotor is diselosed. In general, the system includes a cable at least partially extending substantially adjacent to a tip of the rotor blade. The cable may include a first end secured to the rotor blade or the hub and a second end coupled to a tensioning device. The cable may also be attached to at least one interior wall of the rotor blade between its ends such that the cable is displaced relative to the rotor blade as the blade deflects. The tensioning device may be secured to the rotor blade or the hub and may be configured to maintain a predetermined tension within the cable. Additionally, a sensor may be coupled to at least one of the cable or the tensioning device and may be configured to measure the displacement of the cable.
