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.

Highlights

  • In accordance with the recent changes in international security policies the Hungarian De- fence Forces are going through dramatic and constant changes

  • In my paper I wished to introduce non–destructive testing methods used for aircraft life extension programs

  • It is a really hard and challenging professional job to provide technical support to any equipment used in the Hungarian Defence Forces

Summary

Introduction

In accordance with the recent changes in international security policies the Hungarian De- fence Forces are going through dramatic and constant changes. The Hungarian Defence Forces have JAS–39 EBS HU Gripen fighter aircraft in service. These fourth generation aircraft and all their systems have been manufactured to meet the requirements demanded by “on–condition”. As for technical condition, classical preset life span cannot be defined as such this paper dos not deal with non–destructive material testing techniques used for this type of aircraft. In the following chapters non–destructive material testing techniques used during life extension programs of the previous aircraft types will be introduced

Airframe Damages
Contact Corrosion
Visual Testing
Magnetic Particle Test
Liquid Penetration Test
Eddy Current Test
X–ray Test
Ultrasonic Test
Ultrasonic testing of fibrous composite structures
