Thermography on rotor blades is in the focus of the 29th webinar of the Fraunhofer Institute for Wood Research WKI on March 24, 2015. The online seminar at 2.00 p.m. will be held in english language.
Hidden defects in rotor blades of wind energy turbines can cause huge economic losses and, in the worst case of a breaking blade, threaten human lives. Consequently, the detection of structural anomalies in rotor blades should have the first priority.
Today however, most blades leave production without proper quality control. Moreover, possible damages by transport and assembly are not inspected sufficiently.
WKI's research activities have focussed on methods for detecting defects in rotor blades since many years. Of particular importance are the passive and the active infrared thermography. In such a way, defects such as delaminations, defective adhesive joints, dry laminates, ingress of moisture, but also wrinkles could be detected in many blades.
The webinar comprises the complete field of defect detection in rotor blades by means of thermography. An introduction into the technique of passive and active thermography is followed by a discussion of current problems in rotor blades and their non-destructive detection with the help of many examples.
The webinar will close with an outlook on possible future developments.

For the first time, an interdisciplinary team from the University of Basel has succeeded in integrating artificial organelles into the cells of live zebrafish embryos. This innovative approach using artificial organelles as cellular implants offers new potential in treating a range of diseases, as the authors report in an article published in Nature Communications.
