Abstract

Przedmiotem wynalazku jest łopata (2) turbiny wiatrowej, zawierająca powłokę ochronną (1) na krawędzi natarcia. Powłokę ochronną (1) stanowi warstwa materiału elastomerowego, pokrytego warstwą poliuretanową. Grubość warstwy materiału elastomerowego zmniejsza się stopniowo w kierunku krawędzi spływu. Część powłoki ochronnej (1) znajdująca się nad linią centralną wzdłużną krawędzi natarcia łopaty (2) posiada na całej swojej długości zintegrowany generator vortex. Powłoka ochronna (1) jest nałożona asymetrycznie względem linii centralnej wzdłużnej krawędzi natarcia tak, że większa jej część znajduje się na powierzchni łopaty (2), znajdującej się nad krawędzią natarcia. Powłoka ochronna (1) połączona jest z powierzchnią łopaty (2) za pomocą warstwy spoiwa. Na krawędziach powłoki ochronnej (1) znajduje się uszczelnienie wypełniające (7).The subject of the invention is a wind turbine blade (2) comprising a protective coating (1) at the leading edge. The protective coating (1) is a layer of elastomeric material, covered with a polyurethane layer. The thickness of the elastomer material layer gradually decreases towards the trailing edge. The part of the protective coating (1) located above the longitudinal central line of the blade leading edge (2) has an integrated vortex generator along its entire length. The protective coating (1) is applied asymmetrically with respect to the central line of the longitudinal leading edge, so that the majority of it is on the surface of the blade (2) located above the leading edge. The protective coating (1) is connected to the blade surface (2) by means of a binder layer. There is a filler seal (7) on the edges of the protective coating (1).
