Paper Abstract

An overview is presented of several techniques under development at NASA Langley Research Center for detection and quantification of flaws in aircraft structures. The techniques have been developed as part of the NASA Airframe Structural Integrity Program. The techniques focus on the detection of cracks, corrosion and disbonds in thin laminated structures. The techniques range from thermal procedures which give a rapid indication of the regions of concern to eddy current instrumentation for detecting small cracks and multilayer corrosion. Results are presented on specimens with both manufactured defects for calibration of the techniques and on specimens removed from aircraft.
