ОKО-01 and VD 3-71 universal eddy current flaw detectors and their application for the detection of hidden flaws in one-piece units of aeronautical engineering.
Eddy current technique is exceptionally important for reliable operation of aeronautical engineering. At the initial stage the eddy current technique was widely applied for surface defects detection. However, in the last decades it has been used for subsurface defects detection more and more, including fatigue and corrosive flaws in inner layers of multilayer aerostructures, defects under the layer of sealant, rivet head and etc.
