EO data to assess rain erosion of wind turbine blades

Hasager, Charlotte; Tilg, Anna-Maria; Badger, Merete; Karagali, Ioanna

and grows along the leading edge of the turbine blade towards the hub. Modern turbines have high tip speeds when operating at full capacity, thus when intense rain occurs during those times, the erosion starts and develops. Turbines with eroded blades produce less electricity as the aerodynamic efficiency

Rain erosion atlas for wind turbine blades based on ERA5 and NORA3 for Scandinavia

Hannesdóttir, Ásta; Kral, Stephan T.; Reuder, Joachim; Hasager, Charlotte Bay

Results in Engineering — 2024, Volume 22, pp. 102010

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 atlas for Scandinavia and Finland, based on ERA5 reanalysis and NORA3 mesoscale

Experimental study on the effect of drop size in rain erosion test and on lifetime prediction of wind turbine blades

Bech, Jakob Ilsted; Johansen, Nicolai Frost-Jensen; Madsen, Martin Bonde; Hannesdóttir, Ásta; Hasager, Charlotte Bay

Renewable Energy — 2022, Volume 197, pp. 776-789

Rain erosion of turbine blades causes loss of production and expensive repairs in the wind energy sector. There is a common consensus, that the size of impacting rain drops has a governing effect on the added damage. However, the literature lacks systematic experimental studies on the topic

Assessment of the rain and wind climate with focus on wind turbine blade leading edge erosion rate and expected lifetime in Danish Seas

Hasager, C.; Vejen, F.; Bech, J. I.; Skrzypiński, W.R.; Tilg, A.-M.; Nielsen, M.

Renewable Energy — 2020, Volume 149, pp. 91-102

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 investigate the rain and wind climate at five coastal
