Methodological bases of aircraft elements non-destructive control technologies
(National Aviation University, 2022-11) Haohao, Hu; Хаохао, Ху
In this day and age, aircraft generally have a life expectancy of a few dozen years. To ensure such a long life of the aircraft, it is inseparable from the full efforts of the people behind the aircraft maintenance, repair and overhaul, it is with their full protection, the aircraft can maintain a long period of normal flight. The key to this work is speed and efficiency. After all, the longer an aircraft stays in the maintenance facility, the higher the cost to the operator. In this context non-destructive testing (NDT) is the most economical way to carry out inspections. The structure and different components of an aircraft are made of various materials, and it takes a long time and costs a lot of money to break the aircraft into pieces and inspect each component, so cost effective NDT methods are used in aviation inspection and maintenance. Changes in aircraft materials can also affect the requirements for NDT. Aluminum was once the most common material used in aircraft manufacturing, but now more carbon fiber composites are being used in aircraft manufacturing, bringing new requirements and challenges to NDT. Because composites are more complex, the parts made are subject to a variety of shape changes, and such parts are highly susceptible to failure. Among the various NDT techniques, eddy current inspection is widely used in the aerospace industry because of its advantages such as no contact with the workpiece, fast detection speed and high detection sensitivity.
