Abstract Leading edge erosion of wind turbine blades is one of the most critical issues in wind energy production, resulting in lower efficiency, as well as increased maintenance costs and downtime. Erosion is initiated by impacts from rain droplets

The high strain rate (above ~ 104/s) behavior of an elastomer is characterized using low strain rate (below ~ 101/s) dynamic mechanical thermal analysis and time–temperature superposition. This approach is validated using high strain rate ball impa

Our motivation for investigating the rain and wind climate in the Danish Seas is recent news on leading edge erosion on wind turbine blades at several offshore wind farms. The costs related to turbine blade repair are high. In this study we investiga
