Nondestructive Evaluation (NDE) Technology Initiatives. Delivery Order 0021: Application of an Electrochemical Fatigue Sensor (EFS) Borescope System for Military Turbine Engine Assessment

Abstract

The objective for this project was to improve the United States Air Force's capability to perform fatigue assessment of military aircraft engines through the application of four nondestructive technologies: eddy current inspection, ultrasonic inspection, visual inspection, and the electrochemical fatigue sensor (EFS). EFS is a relatively new technology; the other three inspection methodologies are well established and widely accepted means of component inspection. A 6-mm-diameter inspection borescope, capable of delivering ultrasonic, eddy current, and EFS probes, along with video imaging, to fatigue critical locations within an engine has been developed.
