Abstract

Kunstfaserelemente mit Borsten sind hinreichend bekannt. Speziell zur Geräuschverringerung schnell durchlaufender Flügel und Rotoren spielen sie jedoch keine Rolle. Hinreichend bekannt sind auch Windräder mit den entsprechenden Rotorblättern. Bei ortsnahem Einsatz stellen diese jedoch einen Geräuschfaktor dar, der immer wieder zu Protesten und auch tatsächlichen gesundheitlichen Beeinträchtigungen führen kann. Diesem Problem liegt die in den Patentansprüchen angegebene Erfindung zugrunde. DOLLAR A Durch die Struktur der Kunstfaserelemente, die in die Windabrißkante der Rotorblätter eingebaut werden (siehe Fig. 3) lassen sich diese Nachteile beheben. DOLLAR A Darüber hinaus lassen sich derartige Elemente auch im Luftverkehr bei Maschinen, die besonders geräuscharm sein sollen, einsetzen.
