| Abstract: | Thermal problem of structure has critical effect on the performance of missile and is being studied heavily .As the flight environment of the aircraft is very complicate,it is essential to calculate and analyze the thermal test. In this paper,using structure thermal test method,the antenna cover was studied and the temperature and strain of the critical points were measured.Using the finite element method,the temperature and strain field,which changed with time in the structure,was calculated while the antenna cover was suffering high temperature thermal shock,heat flow and mechanical loading. |
