Analytical solution on transient aerodynamic heating of hypersonic vehicle hot structure

New type hypersonic vehicles become more and more important due to its high performance, safety and low price.Thermal protection system(TPS), Which are correlated to the safety of hypersonic vehicles, are one of the most critical techniques in design and manufacture of hypersonic vehicles.The reusable ceramic tiles, such as C/C, C/SiC and insulator tiles would be susceptible to excessive recession during retry and fatal weakness of UHTCs is prone to thermal fragmentation.An analytical solution of a simplified transient thermal problem was derived for thermal response on non-ablation materials subjected to a simplified heat plus.The solution is introduced two non-dimensional parameters.Analysis of influencing factors on transient thermal response has been performed.Results and data obtained from calculation will gie guidance to thermal protection design.
