A hypersonic missile of aerodynamic/thermal/structural multi-field coupling numerical simulation model is established to predict its thermodynamic environment on the condition of horizontal flight, which is implemented by using partition algorithm, and its flow field and structure-thermal field are analyzed. Results show that: missile body is stretched and expanded on axial direction and on radial direction, respectively, and structural deformation is mainly caused by aerodynamic heating; the thermodynamic environment is severe in missile head; structural deformation has little influence on the distribution of temperature and pressure. Coupling factors could be neglected to enhance numerical simulation efficiency of flow field and structure-thermal field on the condition of horizontal flight, which is meaningful for missile design.
Key words: missile; hypersonic; coupling; horizontal flight
