Weak magnetic detection of aircraft conduit damage

Because of the complexity of the special structure and installation position of aircraft conduit, it is difficult to detect its damage. This paper studies the feasibility of aircraft conduit damage detection based on weak magnetic field detection, outlines common damage types and locations with ANSYS simulation method, and studies the feasibility of weak magnetic field detection and the influence of scanning methods on defect detection of different locations by experiments. Through the analysis of the experimental results, the feasibility of weak magnetic field detection technology in aircraft conduit damage detection is verified, which provides a detection method for aircraft conduit detection.
