Abstract:

This report presents the results of a survey of the potential use of acoustic emission monitoring for specific inspection and maintenance tasks in performance of ground support of Naval aircraft. One potential application, detecting corrosion in composites, is identified as worthy of an implementation study, since the U.S. Air Force has already proven feasibility. Feasibility studies are recommended for AE detection of defects in landing gear, cockpit canopies, fuel tanks, helicopter rotor blades, retreaded tires and fan blades. Research and development programs are suggested for bearing noise analysis, weld inspection, and damage assessment in composites. Author
