Facts
• Over 30% of Blade Maintenance Cost come from Surface defects
• 1/3 of the repairs needs to be repeated
• Visual Inspection Methods are the main Verification Techniques
• Ultrasounds or Eddy Current only provides thickness values of a single layer.
• Typically Highly trained staff is normally required.
• Blade OPEX is at 2.000€/MW.

• Multi-layer NDT measurement of:
o Thickness
o Adherence
o Bonding line defects (up to 10mm depending on the laminate)
• Non-destructive and non-contact
• Very quick – 30 secs/run
• Every layer in one shot
• Plant and field operation
• Non-flat surfaces (e.g. leading-edge)
• Metallic and non-metallic substrate
• It can be automated (example for Car Industry - (Irys)
• Wind | Ship | Aerospace Industries
Facts VALUE PROPOSITION
• Provide better insight on the Blade Quality
• 100% inspection
• More and better information
• Avoid Blade reparations in the field
• Use Cases:
• New blades manufacturing
• Operating Assets Verification
• Second hand market
• Wind farm ownership change 5
TERAHERTZ WAVES
• Co-developed with Fraunhofer Institute • Good spatial resolution (sub-mm) • Good penetration (~cm) • Time-domain (depth information)
6
• A terahertz pulse is sent to the sample in reflection
• Discontinuities in the index of refraction cause different reflections
• Reflections are separated in time due to the thickness of layers
• Analyzing the position and amplitude of the reflections provides information about thickness and type of layer
Components & Principle of Operation
Portable Cart
THz Core – Vacuum system and electronics
Measurement Head
Tactile Interface
Attachment system
Linear Stage
SAMPLE
7
• A terahertz pulse is sent to the sample.
• The sample is scanned along the selected path.
• The ADI (Adherence Index) is derived
• Two interfaces are verified independently
• A Classifier Algorithm separates Pass or Failed
• Inmediate – Cheap – Non-trained
Contactless Adherence – A breakthrough in NDT
PULL-OFF TEST
• Destructive
• Slow (>24hours)
• Expensive
• Laboratory & Plant needed
• Only the weakest interface is tested
• Highly Trained personnel

• NOTUS system works for Complex Metallic substrates:
o Car Industry - (click for video)
o Wind Industry
• Offshore & Onshore support structures
• Components: transformers, gearboxes, generators
o Ship Building Industry
• It can be automated.
• Or work with the same pneumatic head.
• It can measure Wet Paintings

METALLIC SUBSTRATES
• Example:
• 4 layer inspection of steel plates w/
• Multilayer Coating
• Measurement time – 15 seconds
• 4 layers in one shot

Operation
• Initialize and set reference
• Select coating scheme
• Select scan range (30 to 70 mm)
• Select step-size (down to 100 microns)
• Acquire measurement
• Results are automatically displayed and saved
• Export results
• Full traceability
