Device for measuring deformation of rotor blade under load, particularly rotor blade of wind turbine, has receiver arranged at rotor blade and transmitter or reflector is arranged on rotor blade at distance from receiver

摘要

The turbine has a receiver (4) arranged at the rotor blade and a transmitter (3) or reflector is arranged on the rotor blade at a distance from the receiver. The device has a unit for measuring a rotation of the transmitter or receiver to a rotor blade-reference axis. An independent claim is also included for a method for measuring deformation of a rotor blade, particularly by device.
