Wind Turbine Lightning Blade Damage

A lightning strike to an unprotected blade will raise its temperature tremendously, perhaps as high as 54,000° F (30,000° C), and result in an explosive expansion of the air within the blade.

This expansion can cause delamination, damage to the blade surface, melted glue, and cracking on the leading and trailing edges.

Much of the damage may go undetected while significantly shortening the blade’s service life. One study found that wood epoxy blades are more lightning-resistant than GRP/glass epoxy blades;
