Aerothermoelasticity analysis of hypersonic vehicle based on meshfree method
Year: 2025
Type: conference-paper
Abstract: During the flight, hypersonic vehicles are subject to severe aerodynamic heating. It is necessary to consider the close coupling between aerodynamics/structure/heat, which is complicated to a certain extent. The difficulty of introducing thermal effects into pneumatic/structural coupling analysis is that there is a large difference in time scale between thermal conduction analysis and aerodynamic/structural coupling analysis. Based on the finite element method, aero-structure-thermo coupling analysis methods for hypersonic aircraft are quite mature, but certain disadvantages exist in terms of analysis time consumption. The rapid analysis method based on the meshfree method can improve calculation efficiency and ensure the accuracy of analysis results.In this paper, when refer to the rudder surface components, the thermal conduction analysis and structural static analysis methods in the aero-structure-thermo coupling analysis framework are replaced with a meshfree method. .....
