Serrated panel for a wind turbine rotor blade

A wind turbine rotor blade comprising:

• a blade root;
• a blade tip;
• a leading edge;
• a trailing edge;
• an aerodynamic profile;
• a serrated panel arranged on said trailing edge;
• said serrated panel having at least two teeth, each of said at least two teeth having a tip, a base, a length measured in a chordwise direction between said base and said tip, a width measured at said base, wherein said length is larger than said width, and two edges running from said tip to said base, each of said two edges having a tip end-section extending from said tip to an intermediate point of said edge, and a main section extending from said intermediate point towards said base;
• said serrated panel further having a plurality of tines arranged side by side in the chordwise direction, each of said plurality of tines beginning at one of said two edges and extending rearwards;
• all of said plurality of tines beginning in one of said main sections have a same, first length, which is between 20% and 60% of said length of a respective one of said at least two teeth;
• and,
• all of said plurality of tines beginning in one of said tip end-sections are shorter than said first length.
