4 Frequently Asked Questions about "Wind turbine blades damaged"

What is wind turbine blade damage?

Wind turbine blade damage can be classified as surface damage (microcracks on the surface and coatings), resin and/or interface damage (delamination, defects in resin) and structural element damage (with broken or kinked fibers) . The surface damage can be caused by erosion (rain erosion, sand, hail), or small object impacts.

What causes wind turbine blade failure?

The article presents the potential causes of wind turbine blade failures and discusses the severity of the damage induced by these causes. Factors such as strong storm winds, rain, hail, lightning, repeated wind loads, and shear effects are explained as sources of structural damage to wind turbine blades.

How critical is a wind turbine blade to a damage mechanism?

The criticality of the wind turbine blade to a damage mechanism is primarily influence by its location within the blade, as illustrated in the top schematic of Fig. 8 . The leading edge is the area subject to highest loads wherein intermediate ones can be seen in the transitional regions from the cylinder to the aerofoil and plydrop.

What are the damage mechanisms associated with turbine blade failures?

Several cases relating the damage mechanisms associated with blades failures, e.g., corrosion-erosion, carbides precipitation, oxidation, coating degradation, high and low cycle fatigue, and creep, are discussed. To converge the topic, the work focuses on gas and wind turbine blades only.
