摘　　要：高超声速飞行器表面结构,如发动机叶片、内涵道及其排气道等暴露在高温强噪声复合环境中,容易出现热声疲劳损伤问题,因此,结构热声疲劳问题引起了广泛关注。热声疲劳研究对增强这类结构的耐久性和可靠性具有重要意义。本文总结了国内外在飞行器结构热声疲劳领域的研究现状,阐述了在热声疲劳理论研究、仿真分析和试验技术方面所取得的进步。从时间维度回顾了国外自20世纪70年代至今在结构热声疲劳领域的研究情况;按研究单位分类介绍了国内科研院所和高等院校在该领域所开展的工作。在此基础上分析了飞行器结构热声疲劳研究所面临的技术难点问题,指出了尚需进一步研究的方向。The structures of hypersonic vehicle surfaces,engine blades,internal ducts and exhaust ducts may gener⁃ate thermal-acoustic fatigue damage because of high temperature and high-intensity noise environments.Thus,it is of significance to study the thermal-acoustic fatigue problems for improving the durability and reliability of such structures.Thermal-acoustic fatigue problems of aircraft structure have received widespread attention.In this pa⁃per,the research status of thermal-acoustic fatigue problems and the research progress during the theoretical re⁃search,simulation analysis and experimental technology of thermal-acoustic fatigue are summerized both at home and abroad.The research status of structural thermal-acoustic fatigue in foreign countries is reviewed from the 1970s to the present from a time perspective.The work carried out by domestic research institutes and higher educa⁃tion institutions in this field is introduced according to the classification of research units.On this basis,the technical difficulties are analyzed and the further development is proposed during the research on thermal-acoustic fatigue of aircraft structures.
