| Abstract: | The paper introduced a new heat-stress coupling experiment for fiber reinforced silica composite radom. By using gas flow engine and load device, this experiment assessed the strength of radom under ablation. Simulation was carried out base on the experiment. Comparing with simulation results and experiment results proved that the simulation method for radom. Eclipse-stress calculating is correct. This method reflected the strength of fiber reinforced radom, which under ablation, from experiment and theoretical analysis, and provided a new way for fiber reinforced silica composite radom simulating. |
