Abstract

The profile (1-4) of a rotor blade (5) of a wind power plant is characterized in that the main camber line runs beneath the chord at least in sections in the direction of the pressure side (8). The profile is further characterized in that the profile (1-4) has a relative profile thickness of greater than 45% with a position of maximum thickness of less than 50%, wherein a lift coefficient (ca) of greater than 0.9, particularly greater than 1.4 is achieved in turbulent flow.
