Abstract
A system for inspecting a wind turbine blade having a pair of shells surrounding a shear web. The system includes a scanning machine for taking images of an interior portion of the shells of the wind turbine blade, a measuring apparatus for taking numerous measurements of a defect imaged within the shells of the wind turbine blade, and a look-up table for ascertaining the theoretical strength of the wind turbine blade.

A method for inspecting a layered object, comprising:
- performing a scan of an interior portion of a layered object;
- measuring internal and external parameters of a defect within the layered object;
- and
- determining a strength of the layered object based on the measurements of one of the measured internal and external parameters of the defect,
- wherein the strength of the layered object is determined using a look-up table correlating structural strength of the layered object against at least one of the group consisting of an internal aspect ration of defect length to defect height, a ratio of depth of the defect relative to a thickness of the layered object in a plane of the defect, and a ratio of the defect height to a thickness of the layered object in a plane of the defect.
