关键词To a supersonic missile a seeker could enhance the aerodynamic ability due to decrease the resistance in flying. At the same time the primary function of a seeker has been considered as the most important equipment for a missile due to the importance for cueing of targets and tracking for the final approach. However the dome of a seeker which is made up of glass has poor mechanical performance. Especially in the higher altitude for a dome in which the aerothermal and pressure loads could destroy the structure easily it is necessary to do the thermal-structure coupled analysis due to varied materials. In the paper to take the spherical dome of a seeker as a example the analysis has been completed according to the varied materials consist of MgF2 Al2O3 and ZnS. The temperature loads and the pressure loads derived from the results of fluent analysis has been forced on the surface of dome which simulates the actual Mach 2.5 in flying. According to the results of coupled analysis the SEQV stress of the dome radium 80mm based on three materials had reached to 31MPa which shows that the strength is sufficient for Mach 2.5 and offered the warranty to design the attaching to missile for the dome. At the same time the results required the flexible mounting for the dome due to the displacements results which the crystal material couldn't accept. 2011 IEEE.
