Wind Turbine Blade & Main Shaft Inspection Applications

Wind Turbine Blade and Main Shaft Inspection Applications

Inspection target: detection of de-laminations/dis-bonds in turbine blade’s root section (Glass Fiber Reinforced Polymer, GFRP)
Inspection technique developed based on using low frequency conventional and phased array probes & Real turbine blade root section cut out used as calibration piece
Bolt holes and made calibration targets were detected; Backwall trace showed sound penetration up to 4” from the surface
Integrated in Acuren Turbine Blade Inspection program

Blade Root Sections inspected on site and areas with delamination were market on the blade

Inspection target: detection of de-laminations/disbands in turbine blade’s Spar section (Glass Fiber Reinforced Polymer, GFRP and Carbon Reinforced Polymer, CFRP) and adhesive bond
Inspection technique developed based on using low frequency conventional and phased array probes & Real turbine Spar section cut out used as calibration piece

Technique demonstrated detection of dis-bond in both spar cap region and adhesive layer
Inspection technique Integrated in Acuren Turbine Blade Inspection program

Technique detecting cracks in main shaft of wind turbines developed for client
Several shafts tested, one identified as potentially cracked
More sophisticated, high resolution technique proposed for verification and through wall sizing
New technique tested on demo sample cracked all the way through, crack facets clearly imaged
Broader deployment with high resolution technique to be performed in 2024
