All wind turbine blades will experience leading edge erosion at some stage in the assets lifecycle management (ALM). Leading edge erosion is caused by rain, salt spray, sand, insects and ice. Without leading edge protection (LEP), most unprotected blades will show signs of leading edge damage in 2 to 5 years.
High-quality and easy-to-apply Leading Edge Protection (LEP) coating has never been more important to keep up with demand. Wind turbine blades are getting larger with increased tip speeds. The renewable wind industry can rely on us to maintain blade performance and efficiency.
Based on the same technology used in the aerospace industry to protect helicopter blades, thermoplastic polyurethane films provide advanced leading edge protection. They protect wind turbine efficiency, reduce downtime and maintenance and they also extend the performance lifespan of blades in the harshest environments, as well as been very simple to install with the correct know-how.
Leading edge damage manifests itself as pitting on the blade’s surface, especially on the leading edge, where the most impact will occur. This leading edge erosion causes a reduction in aerodynamic efficiency and a loss in operating performance. Some studies have shown that leading edge erosion can result in a drag increase of up to 500%, leading to a decrease in annual energy output of up to 20%. The effects of this wind turbine rotor blade damage can be apparent in as little as two years from installation. Wind turbines can be reasonably expected to perform continuously for 15 or more years. This means erosion is a significant problem for operators. Once installed, retrofitting of LEP should be a strong investment.
