摘要：

In this paper, the radome of 3/4 power series generatrix is taken as the object of study, and fluid-thermal-structure coupling field of it is simulated and analyzed with sequential coupling method. The aerodynamic load under Ma=6 flight condition is calculated using ke-standard model. Then the finite element method is used to make structure thermal analysis and simulate the temperature field and strain field. The results show that the maximum thermal stress, strain and deformation of the structure always occur at the tip of the structure where the thermal expansion effect is obvious. The calculation results can provide an effective theoretical reference for the design of hypersonic vehicle structures and thermal protection systems.
