In order to satisfy the aerodynamic shape requirement of hypersonic vehicles, a curved multi-layer integrated thermal protection system (ITPS) is developed in this paper. The ITPS consists of a ceramic matrix composite layer, a lattice sandwich layer and a glass wool layer. The curved ITPS samples are fabricated. Then experimental test and numerical simulation are carried out respectively to evaluate the heating insulation effect of the ITPS samples. In addition, a series of numerical simulations are conducted to investigate the influences of lattice configuration and gradient layer layout on the heating insulation and load bearing capability of the ITPS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
