Innovative Ultrasonic Wind Rotor Blade Inspection

The quality of glass- and carbon fiber reinforced composite structures in wind turbine blades is an important topic for both manufactures and turbine operators. However, quality assessments of rotor blades have been a challenge for the entire wind community due to: (1) lack of inspection standards, (2) a demand for a more cost effective production and (3) a limited accessibility to the blades. The paper discusses a number of non-destructive automated ultrasonic solutions for inspection of the wind rotor blade throughout its lifetime. Different aspects of automated ultrasonic inspection are discussed addressing problems related to the design, manufacturing and operation of wind rotor blades. It is concluded that quality assessments of wind rotor blades will benefit from automated ultrasonic inspection throughout their lifetime.
