Abstract Scope The increase in size and weight of payloads for future Mars missions represents an important challenge for current supersonic parachute technology. An alternative technology developed by NASA is the Hypersonic Inflatable Aerodynamic Decelerator (HIAD). To protect the decelerator and payload during hypersonic atmospheric entry, HIADs use a soft deployable thermal protection system made of a lay-up of flexible insulators and heat-resistant woven-fiber ceramic skin. This talk focuses on thermal conductivity experiments and high-fidelity computational simulations of thermo-mechanical behavior in alumina Nextel BF20 woven fibers. We study the 3D anisotropic heat conduction through flexible ceramic fabrics under compression strain by hot-disk transient plane source experiments and advanced finite-element simulations. The newly developed finite-element model is then used to study the overall thermal behavior of lay-up structures at high-temperature under heat flux conditions that are typically encountered in plasma-torch experiments and reproduce hypersonic aerothermal environments.
