Abstract (en)

[origin: WO2019179583A1] A device for remedying erosion problems on a wind turbine blade (1). The device is characterized in that it comprises a shock-absorbing and erosion-resistant and UV -resistant profile (4) for positioning on the front edge of a wind turbine blade (1), which device further comprises a holding part (5) at the leading edge of the blade, which holding part (5) is formed in the blade (1) during the blade-molding process or after-mounted. In the holding part (5) a groove with two recesses facing each other is formed, and in these two recesses two complementary flaps (6) of the profile are engaged and fixed by integrated wedges and the outer part of the profile (4) is designed to match the blade profile.
