<p>The blade (1) has a turbulator (6) extending along a longitudinal axis (21) of the blade and to pressure and suction sides (2, 3). The turbulator has a constant asymmetric height in a direction transverse to the longitudinal axis, where the height lies between 0.3 and 1 mm. The turbulator has valley-shaped parts that are arranged along the longitudinal axis. The turbulator has a coating that includes lacquer layers, a grit, an adhesive foil, a filling compound, a polymer layer and/or a plastic layer. The turbulator is arranged on the pressure side.</p> |
