Why is Wind Turbine Blade Inspection Important?
A wind turbine blade is made of fiberglass and composite resins, which are prone to a variety of problems when exposed to the right conditions. The slightest defect in a blade's surface can potentially reduce the aerodynamic efficiency, resulting in reduced energy output.
Surface Inspection
A surface inspection identifies problems using visual techniques such as cameras, drones, or the human eye. Visually, the following flaws are detected:
- Surface flaws
- Erosion at the leading edge
- Lightning strikes
- Bird Strikes
- Delamination
- Splits on the leading or trailing edge
The benefit of regular wind turbine surface inspections is the ability to perform corrective maintenance. Detecting defects early allows for repairs that extend the life of a component without reducing energy production.
Sub-Surface Inspections
The internal structure of turbine blades is prone to failure both during manufacturing and in service. Subsurface inspections employ the following techniques to detect structural flaws:
- Thermal Imaging
- Ultrasound (Acoustic)
- Electromagnetic.
- Visual examination of the structure
Because of contact-less technologies that can see through thick composite coatings without deconstructing them, subsurface inspections are non-destructive. When the wavelength of electromagnetic or ultrasound waves becomes abnormal, the waves detect defects.
Visibility through the surface aids in the detection of damaged shear webs (structural blade supports), cracks, manufacturing damage, and bonding erosion.
