PROFILE OF A ROTOR BLADE AND ROTOR BLADE OF A WIND POWER PLANT
摘要
The invention relates to a profile (1-4) of a rotor blade (5) of a wind power plant. The profile (1-4) according to the invention is characterized in that the skeleton line runs at least in segment below the chord in the direction of the pressure side (8). The profile according to the invention is further characterized in that the profile (1-4) comprises a relative profile thickness of greater than 45% at an airfoil 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.
