New Rotor Blade Profiles Performance Decay in Horizontal Axis Wind Turbines Operating in Aggressive Environment

At the present time many wind power plants have been developed in mountainous areas, in off-shore sites also at high latitudes and however operating in harsch climate or aggressive environment conditions. In these conditions HAWT’s rotor blades may experiment erosion, corrosion, exfoliation and icin...
