Illuminated the principle of transient thermal transfer analysis. Accomplished the transient thermal analysis based on the model of ellipsoidal dome  and studied the influence about the different material and the different velocity. Considered three materials consist of MgF2  Al2O3  and ZnS  and meanwhile  the velocity was Mach2.5  and the time consists of 10s  20s and 60s. The temperature initial loads were from FLUENT thermal simulation. The thermal conduction analysis and the thermal convection analysis were finished in software ANSYS  in which the entire transient thermal analysis consists of modeling  meshing element  calculating and getting the results. The different temperature distributions based on varied time were gotten about the different materials. The results from analysis showed the temperature distribution of the structure of ellipsoidal dome  which could help the following coupled thermal-structure analysis. 2011 IEEE.
