Abstract

The invention relates to an airfoil, in particular for a wind or fluid medium turbine, comprising a camber between an upper and a lower surface extending between a leading edge and a trailing edge distanced by a chord length, the camber comprising a thickness profile perpendicular to the direction along which the chord length is measured. Furthermore, the invention relates to a wind (or any gas/fluid medium) turbine comprising at least two of the inventive airfoils, and further a wind rotor arrangement comprising an additional stator structure. According to the invention the lower surface is shaped such that the thickness profile comprises a discontinuous step separating the lower surface in a first and second section.
