| Abstract: | Three critical technologies of simulation analysis on thermal-loads of radome in flight are selescted to study in this paper.Section 2 analyzes the first critical technology,which is modeling of the radome and the antena.The computational fluid dynamics software FLUENT is used to analyse the radome,so as to achieve the temperature distribution of its outer surface.Section 3 analyzes the second critical technology,which is to estiblish the multi-cavity thermal radiation model of the radome in order to get th... |
