The effect of leading edge erosion to the flow is studied experimentally by standard method of Particle Image Velocimetry. Three airfoil models are manufactured: the reference one, the homogenously eroded one, which is modeled by putting a sheet of sand-paper to its leading edge and the airfoil with large erosion, which is modeled by regular spikes and a valley in sub-stagnation area. The damaged airfoils support earlier transition to turbulence; in fully turbulent regime, their wake is wider than in the smooth case and, especially in the case of regular spikes, the spanwise fluctuations are reduced.
