ROTOR BLADE OF A WIND TURBINE

摘要

A rotor blade (5) of a wind turbine, which has a profile (1-4) having an upper side (suction side) (7) and an underside (pressure side) (8). The profile (1-4) includes a camber line (21, 25) and a chord (18) between a leading edge (10) and a trailing edge (11) of the profile (1-4). The profile (1-4) has a relative profile thickness of more than 45%. At least one vortex generator (50, 50′, 50″, 50′″) is disposed, in the region of the profile (1-4), on the suction side (7) of the rotor blade (5). The profile (1-4) is provided with a blunt trailing edge. And, The thickness of the trailing edge is between 15% and 70% of the chord length.
