Abstract
The invention relates to a device for detecting icing and de-icing of a wind turbine blade, characterized in that it comprises: a sensor, placed on the surface of a blade, and comprising a first so-called “receiving” antenna, a second so-called “emitting” antenna, and a frequency divider inserted between said first and second antennas; and an interrogator, configured to emit an electromagnetic wave towards the receiving antenna of said sensor, and to receive an electromagnetic wave from the emitting antenna of said sensor.
Claims14
A device for detecting icing and deicing of a wind turbine blade, the device comprising:
- on the one hand, a sensor placed on a surface of a blade, and comprising:
- O-a first antenna, called “receiving antenna”,
- O-a second antenna, called “emitting antenna”,
- O-a frequency doubling device interposed between said first and second antennas, and
- on the other hand, an interrogator configured to emit an electromagnetic wave towards the receiving antenna of said sensor, and to receive an electromagnetic wave originating from the emitting antenna of said sensor.
