飞行器结构热声疲劳问题研究进展

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.
