摘要：
A method for inspecting at least one rotor blade of a wind turbine for damage, such as subsurface blade cracks, includes 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 the at least one acoustic emission sensor, and detaching the at least one acoustic emission sensor from the surface of the rotor blade after the inspection. An inspection system for a rotor blade of a wind turbine is also contemplated.
