Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract
To enable GE Aircraft Engines to meet stringent engine inspection requirements a new eddy current inspection technology has been developed — the Eddy Current Array Probe (ECAP) [1]. The ECAP is based upon flexible micro-fabricated eddy current sensor elements that are capable of conforming to complex geometries. The technology has been used quite successfully by GE Aircraft Engines to inspect fracture critical aircraft engine components in a manufacturing environment.
