吸气式高超声速飞行器热气动弹性研究进展

Nowadays the air-breathing hypersonic vehicles are focused on by the researchers of aeronautics and astronautics. This type of vehicle usually uses a scramjet engine and an integrated design method, which brings a series of aeroelastic problems. This paper first describes the research progress of integrated airframe/engine modeling of air-breathing hypersonic vehicles. Then the research status of aerothermoelastic dynamics is introduced from the aspects of aerothermoelastic/propulsion coupling, control system coupling and uncertainty analysis. The related aerothermoelastic experimental research is analyzed. Finally, several suggestions for the study of aerothermoelastic problems of air-breathing hypersonic vehicles are proposed.
