Abstract

The purpose of this study was to test the sensitivity of thermographic imaging for detection of deeply buried flaws in a structure. The flaws of interest are adhesive debonds underneath 3/8″ of steel and 1/4″ of rubber insulation. This study was stimulated by the necessity of increasing the reliability of solid rocket motors. Consequently, the specimen and techniques described were chosen with this task in mind.
