Atmospheric Re-entry Thermodynamics: Stagnation Enthalpy, Ablative TPS Physics and the Engineering Limits of Hypersonic Return
A deep technical analysis of atmospheric re-entry thermodynamics: Rankine-Hugoniot shock relations, Fay-Riddell stagnation heating, ablative TPS mass pyrolysis, plasma sheath ionisation, and the non-equilibrium aerothermochemistry that defines the design envelope for every crewed vehicle returning from orbit.
