Advanced ultrasonic NDT techniques for wind turbine blade inspection

摘要

This paper presents the development of inspection strategies intended to ensure the quality of the wind turbine blade manufacturing process, and in particular adhesive bond lines. It describes an innovative ultrasonic testing approach that combines specially-developed hardware (the Windblast~(TM) inspection system with hand-held scanner and conformable arrays), signal processing, and evaluation tools for the quality control of large and complex GFRP structures.
