Sensor for wind turbine monitoring (Aerogust)
Launched in 2015, the main objective of the project is to investigate and develop improved simulation methods for gusts on blades, aircrafts wings, composites. IDIL produced, with its partner FEBUS, a complete Fiber Bragg Grating (FBG) interrogation system to measure static and dynamic pressure, temperature and strain specifications of a wind blade.
IDIL and Febus installed the sensors all along one blade. The bare gratings are monitored by an interrogator placed directly inside the rotor of the turbine. The data are imported with 3G transmission. The FBG has been photo imprinted on SMF1550 nm fiber in clean room. A specific packaging has been developped for pressure sensors. The fiber sensors have been directly glued on the blade with a specific glue.
