Wind Turbine Blades, do they need any maintance?

Well, this main component need maintenance as well and they cannot simply be ‘fit and forget’ items. They are subject to bird strikes; lightning strikes; leading edge erosion – especially towards the tips that can be moving through the air at around 200 mph, sometimes in sand and salt laden air – trailing edge damage; and material fatigue; plus surface erosion from rain, hail, ice and insects. Even without actual damage, surface roughness caused by minor pitting and particle accretion can spoil the aerodynamic efficiency of the blades, detracting from turbine productivity.
