Title: Damage Detection in Aircraft Using Giant Magnetoresistance Sensors and Remote Field Eddy Current Techniques
Agency / Branch: DOD / USAF
Contract: N/A
Award Amount: $99,945.00
 

Abstract:

We propose the development of an improved crack and corrosion detection system for hidden defects in multilayered metal structures typical of aircraft. Remote field eddy current (RFEC) techniques will be combined with an array of sensitive, broadband, giant magnetoresistance (GMR) sensors to detect damage deep within the structures. The system offers improved detection without the limitations of skin effects common to conventional eddy current methods, or the frequency limitations of commonly used induction coil sensors. In Phase I we will model and explore the advantages of the RFEC technique combined with an array of sensors. We also propose to develop a GMR sensor specifically suited to the detection requirements. In Phase II we would use the developmental studies to build a prototype system.
