Using the Pulsed Eddy Current Techniques for Monitoring the Aircraft Structure Condition

Abstract It is known that during operation, the aircraft construction materials are exposed to significant mechanical loads and changes in temperature for a very short period of time. All this leads various defects damages assemblies units need be inspected safe operation aircraft, their assemblies, units. In some cases, implementation inspection or diagnostic accompanied by emergence technical difficulties caused large size limited access local places. Under such conditions, ensuring possibility diagnosis hard-to-reach places object becomes especially important. The problem can solved applying wireless technologies. allows spatial separation probes signal processing units, which simplifies scanning surfaces article, description developed system eddy current structural given. Experimental results given form distribution values probe informative parameters (amplitude, frequency decrement) along coordinates.
