Reentry vehicles face extreme heating beyond conventional protection limits. Transpiration cooling offers high efficiency with minimal coolant and reusability. This study uses additive manufacturing to fabricate precise lattice structures, investigating cooling performance under varying coolant flow rates to advance thermal protection systems for hypersonic vehicles.
