Abstract
A method for calculating a trailing edge that is to be produced for a rotor blade of an aerodynamic rotor of a wind power installation, wherein the rotor blade has radial positions with respect to the rotor, the rotor blade has a local blade profile that is a function of the radial positions with respect to the rotor and the trailing edge has a jagged profile having a plurality of spikes, wherein each spike has a spike height and a spike width, and the spike height and/or the spike width is calculated as a function of the radial position thereof and/or as a function of the local blade profile of the radial position thereof.

A method comprising:
- forming a rotor blade for a wind power installation, the rotor blade having radial positions with respect to the aerodynamic rotor when the rotor blade is attached to the aerodynamic rotor, the rotor blade having a local blade profile that is dependent on the radial positions with respect to the aerodynamic rotor and a trailing edge, the trailing edge including a jagged profile having a plurality of spikes, each spike having a spike height and a spike width, wherein at least one of spike heights and spike widths are calculated as a function of at least one of a radial position of the respective spike and a local blade profile of a radial position of the respective spike.
A rotor blade of an aerodynamic rotor of a wind power installation, comprising:
- a rotor blade body having radial positions with respect to the rotor, wherein the rotor blade has a local blade profile that is dependent on the radial positions with respect to the rotor;
- and
- a trailing edge coupled to the rotor blade body and having a jagged profile with a plurality of spikes, wherein each spike has a spike height and a spike width, and at least one of the spike height and the spike width is a function of the radial position of the respective spike and a local blade profile at the radial position of the respective spike.
