There are many overall technical objectives that will be achieved by the end of the WINTUR demo project:

  1. Installation of novel light weight and flexible transducers on the blade able to detect the onset of damage that were the occurrence of fibre breakage due to staged development of a hole-defect.
  2. Combination of different NDT techniques based on the guide wave Ultrasonics such as Long Range Ultrasonic LRU and acoustic emission.
  3. A sequence of signal processing techniques (FFTs, averaging, amplification) to overcome problems of ultrasound attenuation.
  4. Utilisation of Energy Harvesting as a system to harness the surrounding environmental energy for the purposes of powering the sensors.
  5. Use of short-range wireless protocol techniques to transfer data from the pulser/receiver unit to the central control in the nacelle.
