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.

Each disciplinary has its own modeling and analysis tools to solve its own specific field problems. In order to achieve integrated simulation of high precision space optical systems and predict optical performance respective to the mechanical and thermal loads
data must pass through different analysis tools. Simulation tools used in the thermal
structural and optical design process and the relationship among them were first depicted and the integrated simulation methods were described in detail. Zernike polynomial fitting methods and interpolating approaches were also demonstrated. Because of the orthogonality of Zernike polynomials
it was not probably used in some situations such as noncircular apertures and discrete data
and the coupling of Zernike polynomial coefficients and other methods were also introduced in the paper. The toolkit OMTIA (Optical
Mechanical and Thermal Integrated Analyzer) based on the methods was developed
which appears as an indispensable tool for engineering practice.
