| 摘要 |
<p>The invention relates to a rotor blade (5) of a wind turbine. The rotor blade has a profile (1-4), which has a top side (suction side) (7) and a bottom side (pressure side) (8). The profile (1-4) has a mean camber line (21, 25) and a chord (18) between the front edge (10) and the rear edge (11) of the profile (1-4). The rotor blade is characterized in that the profile (1-4) has a relative profile thickness of more than 45%, at least one vortex generator (50, 50', 50'', 50''') being arranged in the region of the profile (1-4) on the suction side (7) of the rotor blade (5), the profile (1-4) having a blunt rear edge, the rear edge thickness being between 15% and 70% of the chord length.</p> |
