Overview of the development of full-scale fatigue test technology for fighter

Abstract

Structural strength is a key concern in fighter′s design and development. Fatigue strength of an aircraft determines important indicators such as safety, durability and reliability of the aircraft. Full-aircraft fatigue test is an important method to verify whether the fatigue strength of aircraft structure meets the design requirements. This paper introduces the development history and current situation of the full-aircraft fatigue test technology at home and abroad, comprehensively analyzes the full-aircraft fatigue test technology in our country, and summarizes the important technical achievements of the full-aircraft fatigue test of a new type of fighter, including aspects of test load spectrum, load, boundary simulation, power system, data processing, damage detection, health monitoring, and so on. In this paper, the development plan and suggestions of the whole aircraft fatigue test technology are given. This research can provide important technical support for other aircraft fatigue tests.
