Non–destructive Material Testing (Ndt) Techniques Applied for the Life Extension Program of the Aircraft in the Hungarian Defence Forces

Abstract

Most aircraft in the Hungarian Defence Forces (HDF) were planned back in the 1960s and 70s. Accordingly, strategies of operating and maintaining these aircraft reflect the level of engineering, technology and diagnostics of that era. However, since the mid 1990s until today a new generation of modern aircraft (JAS–39 EBS HU Gripen, MiG–29 tactical fighter aircraft) have been used in the Hungarian Defence Forces. By using these third and fourth generation fighters, new, modern operating and maintenance environment and systems have also been introduced. This publication is aimed at providing a short overview of Non–Destructive Material Testing; a very special segment of the many diagnostic testing methods used during life extension programs.

Review of Advanced Welding and Testing for Safety in Offshore Oil and Gas

“…Magnetic Particle Inspection is a surface-based NDT method used to detect surface and near-surface defects in ferromagnetic materials (Bozóki, 2014). The process involves applying magnetic particles to the surface of the weld, and the presence of defects creates magnetic fields that attract the particles, making the defects visible.…”
