Atmospheric Drivers of Wind Turbine Blade Leading Edge Erosion: Review and Recommendations for Future Research
Pryor, Sara C.; Barthelmie, Rebecca Jane; Cadence, Jeremy; Dellwik, Ebba; Hasager, Charlotte Bay; Kral, Stephan Thomas; Reuder, Joachim; Rodgers, Marianne; Veraart, Marijn (Journal article; Peer reviewed, 2022)Leading edge erosion (LEE) of wind turbine blades causes decreased aerodynamic performance leading to lower power production and revenue and increased operations and maintenance costs. LEE is caused primarily by materials ... -
Failsafe layer for wind turbine blades: Erosion protection of glass fiber composite through nanodiamond-treated flax composite top layer
Hinzmann, Carsten; Johansen, Nicolai Frost-Jensen; Hasager, Charlotte Bay; Holst, Bodil (Journal article; Peer reviewed, 2024)Wind turbine blades are mainly made from E-glass fiber (GF) epoxy composites, because of their good ratio of strength to weight and costs. With the increase in blade length and tip speed, the problem of leading edge erosion ... -
Rain erosion atlas for wind turbine blades based on ERA5 and NORA3 for Scandinavia
Hannesdóttir, Ásta; Kral, Stephan Thomas; Reuder, Joachim; Hasager, Charlotte Bay (Journal article; Peer reviewed, 2024)Leading edge erosion on wind turbine blades is a common issue, particularly for wind turbines placed in regions characterized by high wind speeds and precipitation. This study presents the development of a rain erosion ... -
Towards greener wind power: Nanodiamond-treated flax fiber composites outperform standard glass fiber composites in impact fatigue tests
Hinzmann, Carsten; Johansen, Nicolai Frost-Jensen; Hasager, Charlotte Bay; Holst, Bodil (Journal article; Peer reviewed, 2024)Wind energy is facing two major problems, recyclability of wind turbine blades, primarily made from fiberglass, and rain erosion on the blade’s leading edges. Here, we show that flax fiber reinforced epoxy composites have ...
