Abstract: A method for repairing a leading edge of wind turbine blade is provided. In the method an adhesive is applied to an eroded surface of the leading edge of the wind turbine blade for substantially re-establishing geometry of the leading edge of the wind turbine blade. Thereafter, a leading edge protective shell is applied on the leading edge such that the leading edge protective shell adheres to the eroded surface with only the adhesive between the eroded surface and the leading edge protective shell, wherein a shape of the leading edge protective shell corresponds to aerodynamic outer profile of the leading edge. A two component modified-silane polymer adhesive is used to mount a soft polymer leading edge protective shell.
