“…Other studies examined new metallic TPS concepts. The Multiwall TPS was studied using a combined analytical and experimental approach that include radiant-heat, windtunnel and lightning strike tests [43]. Numerical simulation were conducted on superalloy honeycomb TPS to determine its thermoelastic response [21].…”

“…Included in this table is a list of materials and their design temperature limits. Recent developments, such as tailorable advanced blanket insulation (TABI) 6 and multiwall tile, 7 were included in leeward thermal protection analyses. Polyphenylene oxide (PPO) foam, which has shown promise as a cryogenic insulation, 8 was also considered in the analyses.…”

A trade study was performed to obtain a lightweight thermostructural concept for application to a hypersonic vehicle. Aerothermodynamic environments and structural design loads were defined for a selected configuration and given flight trajectory. Thermostructure was sized through the thermal and structural analyses. The trade study included integral vs nonintegral tanks and hot vs thermally protected structures. Material and design options were also explored in this study.

“…While there are variety of TPSs classified based on the materials being used and service conditions (aero-thermal loads), the present work is focussed mainly on metallic TPSs. Metallic TPS uses a fundamentally different design approach than ceramic tile and blanket concepts and falls under reusable category [3–5]. Metallic TPS concept decouples the thermal and structural functions by providing a metallic shell to encapsulate internal insulation, maintain panel shape and withstand mechanical and thermal loads [4–7].…”

Metallic thermal protection systems comprising of sandwich panels consisting of hexagonal honeycomb sandwich structures are envisaged to be used in advanced transportation systems like hypersonic vehicles and reusable launch vehicles. The assessment of compressive mechanical behaviour is necessary to understand the response of sandwich structures to aerothermal loads. The fabrication methodology for realizing Ni based superalloy Superni 263 hexagonal honeycomb sandwich panels is established. This work is aimed at understanding the effect of sandwich panel geometry parameters like hexagonal cell size and core thickness on the out-of-plane flatwise compressive behaviour at room temperature. The ultimate compressive strength decreases with increasing core height irrespective of the cell sizes investigated. The dependence of specific compressive strength on the cell size is established by a power law relationship. The compressed sandwich panels subjected to understand the deformation behaviour indicated the dominance of cell wall bending and occasional fracture, however in the case of sandwich panels with higher core thickness cell wall buckling coupled with shearing at the face sheet vicinity is noticed.
