Description
Summary:Aircraft fuselage is subject under the influence of many negative factors during its operation. Non-destructive testing methods are primarily used to minimize the possibility of possible failure. For early detection of any anomalies that may occur at aircraft fuselage are used mainly electromagnetic non-destructive testing and evaluation methods. This paper deals with inspection of riveted joints of the fuselage and wings of aircraft Zlin 142. The aircraft manufacturer determines the prescribed time intervals for the inspection of the fuselage. During the inspection, we will try to detect possible cracks and reveal a presence of hidden corrosion. A suitable method for the inspection of these riveted joints is eddy current testing method (ECT). Eddy current testing is one of the widely utilized electromagnetic NDE methods. It works based on an interaction of time-varying electromagnetic field with a conductive structure according to the Faraday’s electromagnetic induction law. This electromagnetic method is suitable for reliable detection of surface and subsurface defects of the riveted joints. Experiments will utilize Olympus OmniScan MX device with presence of ECA module. Eddy current array probes SAB-067-005-032 and SBB-051-150-032 are used, respectively. Harmonic eddy current excitation is used for this purpose.
