Abstract (en)
[origin: CA2886493A1] The invention relates to a wind turbine rotor blade comprising a suction side (216), a pressure side (217), a region (214) near the root, a rotor blade tip (213), a rotor blade front edge (211), and a rotor blade rear edge (212). Said rotor blade also has a plurality of stagnation points along the length of the rotor blade, which together can form a stagnation point line (215). A plurality of vortex generators are provided in the region of the stagnation point line (215) which is located on the underside (generally referred to as the pressure side) of the rotor blade.
