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, loading and bearing, boundary simulation, power system, data processing, damage detection, health monitoring, and so on. This paper provides important technical support for other aircraft fatigue tests and proposes the development direction and planning for the full-aircraft fatigue test technology.
