Abstract

Die Erfindung betrifft ein Profil (1-4) eines Rotorblatts (5) einer Windenergieanlage. Das erfindungsgemäße Profil (1-4) zeichnet sich dadurch aus, dass die Skelettlinie wenigstens abschnittsweise unterhalb der Sehne in Richtung der Druckseite (8) verläuft. Außerdem zeichnet sich das erfindungsgemäße Profil dadurch aus, dass das Profil (1-4) eine relative Profildicke von mehr als 45 % bei einer Dickenrücklage von weniger als 50 % aufweist, wobei ein Auftriebsbeiwert (ca) bei turbulenter Umströmung von mehr als 0,9, insbesondere mehr als 1,4, erreicht wird.
