The result is removal of material and formation of cracks due to pluvial erosion, which leads to increasingly deteriorating aerodynamic properties of the blade. These changes not only have a negative impact on the efficiency of wind power plants (WPP), they also cause higher noise emissions.
The problem will only be exacerbated in the future, as rotors will have to turn faster to increase the efficiency of offshore WPPs: As the speed increases, raindrops will strike the coatings with even more energy, which will lead to damage sooner.
Rough spots and damage to the paint and coatings are especially common on the leading edge of the blade, at the tip of the blade. They have a negative impact of the aerodynamic properties of the Wind Power Plant and detract from performance.
