Abstract
A method and apparatus for detecting structural anomalies in the body of rotating members of an engine involves establishing an electric circuit in the body of the rotating members by embedding a network of electrically conductive fibers. Upon rotation of the members in the presence of a magnetic field, an electric current flows in the electrically conductive fibers of the rotating members. Detection of a structural anomaly in any of the rotating members results from detecting a break of the electric circuit.
