    Abstract:

    The structures of hypersonic vehicle surfaces, engine baldes, internal ducts and exhaust ducts are pronse to thermal-acoustic fatigue damage when exposed to high temperature and high-intensity nosie environments. Thus, it is of more significance for improving the durability and reliability of such structures to study the thermal-acoustic fatigue problems. On the basis of literature review and summarization, this paper comprehensively ealborated on the new progress in the research of thermal-acoustic fatigue problems of aerocraft structures both domestically and internationally. Firstly, the research status of structural thermal-acoustic fatigue in foreign countries was reviewed from the 1970s to the present from a time perspective. Then, the work carried out by domestic research institutes and higher education institutions in this field was introduced according to the classification of research units. It showed that significant progress had been made in the theoretical research, simulation analysis and experimental technology of thermal-acoustic fatigue both domestically and internationally after half a century of development. The technical difficulties faced by the research on thermal-acoustic fatigue of aerocraft structures and the issues that need further research were also discussed at last.
