Abstract

A method and system for inspecting a wind turbine is provided. The method includes providing at least one remotely operated aerial platform (ROAP), providing at least one non-destructive evaluation (NDE) device attached to the ROAP, and providing at least one distance measuring system attached to the ROAP. The distance measuring system is used for determining the distance between the ROAP and at least a portion of the wind turbine. The method also includes positioning the ROAP so that the at least one non-destructive evaluation device captures data used for inspecting the wind turbine.
