Abstract
A rotor blade for a wind turbine is provided. The rotor blade includes a high lift root profile with flat-back trailing edge with a suction side and a pressure side, a relative airfoil thickness being between 45% and 75% or between 48% and 70% of a chord length. A trailing edge thickness is between 30% and 75% or between 35% and 60% of the relative airfoil thickness. The chord position of the maximum relative airfoil thickness, which is measured from a leading edge towards the trailing edge, is between 35% and 45% or between 36% and 42% of the chord length. Also provided is a wind turbine equipped with the rotor blade(s).
