We study the ablation and transient pyrolysis outgassing of the carbon-phenolic ablators
AQ61 and Asterm in air and nitrogen plasmas. We investigate their resistance to high …

Under hypersonic flow conditions, the heat and mass transfer at the gas-solid interface of
thermal protection material becomes highly complicated due to the strong chemical and …

This thesis focuses on the coupling between flow, ablation, and radiation phenomena
encountered in the stagnation region of atmospheric entry vehicles with carbon-phenolic …

Testing thermal protection system materials in ground-based facilities, such as plasma wind
tunnels, is a key step in the development of entry vehicles. The Local Heat Transfer …

Accurate prediction of the gas-surface interaction during spacecraft reentry remains a
challenging problem for thermal protection system design. Attempts to model the surface …

Next generation spacecraft will bring back heavier payloads from explored planets. Advance
in the modeling of the thermo-chemical ablation of carbon-based thermal protection system …

Designing thermal protection systems (TPS) for ballistic reentry capsules requires both
reliable numerical tools and experimental facilities to evaluate surface ablation and its …

Ablative materials are extensively used in aerospace applications to protect the integrity of
the spacecraft during atmospheric entry. Both thermal and mechanical stresses have to be …

The exploration programs of our solar system involve the design of manned or unmanned
spacecraft that enter a planet atmosphere at hypersonic velocity. After the successful …

Surface chemical effects have great influence on the prediction of hypersonic
nonequilibrium aerodynamic heating, and they are particularly complex in a dissociated …
