This Zenodo record contains the complete theoretical proposal and analysis for the Micro-Sphere Enhanced Ablative Layer (MSEAL) concept—an innovative thermal protection system enhancement for hypersonic reentry vehicles like NASA's Orion capsule. The work includes: The full research paper (PDF) detailing the concept, theoretical analysis, and implications for the Artemis program. Complete Python code for parametric performance analysis. All simulation results and data files. Summary visualizations and technical tables. The MSEAL concept addresses char loss issues observed in Artemis I by embedding ceramic micro-spheres into the Avcoat ablator to modify the boundary layer and enhance pyrolysis gas venting, potentially reducing convective heat flux by 5-16%.
