Abstract
This paper describes the use of time-resolved infrared radiometry (TRIR) to identify characteristic temperature-time signatures resulting from different subsurface thermal structures in aging aircraft. Central to the TRIR technique is the analysis of the temperature- time signatures at various locations as a step heating pulse is applied to the structure. Of particular interest is determining whether a signature can be identified which discriminates the presence of corrosion product from the simple thinning of the aircraft skin as might occur as a result of a previous repair. A technique is proposed which implements both area and localized heating sources. The area heating source provides one-dimensional heating of the specimen and allows suspect areas to be rapidly detected. A localized heating source is then used to further characterize the suspect regions.
