The invention relates to a method for inspecting at least one rotor blade of a wind turbine for damage such as subsurface blade cracks. The method comprises the steps of: attaching at least one acoustic emission sensor to a surface of a rotor blade to be inspected, exciting oscillations in the rotor blade for a time period, measuring activity signals of the oscillations in the rotor blade with said at least one acoustic emission sensor, and detaching said at least one acoustic emission sensor from said surface of said rotor blade after said inspection. The invention also relates to an inspection system (9) for a rotor blade (5) of a wind turbine (1). |
