Research Progress and Prospect of Thermal Flutter of Hypersonic Vehicles

Abstract

Hypersonic vehicle is subjected to severe aerodynamic load and aerodynamic heating during the flight.Thus structural dynamic stability and response caused by aerodynamic force and aerodynamic heating should be fully considered in the design process of structure,in hypersonic vehicles the thermal flutter is one of the key parts. In this paper,the development of thermal flutter research is reviewed,various existing methods for thermal flutter research are summarized,including thermal modal test,thermal flutter simulation analysis and wind tunnel test. On this basis,the research status and existing problems of ground flutter test,which can be used in the study of thermal flutter,are summarized,and the future development trend of ground thermal flutter test is prospected.
