The development of a Thermal Protection System (TPS) is crucial for reusable space vehicles to protect from extremely high temperatures during atmospheric re-entry, caused by air friction and shockwaves leading to adiabatic compression effects. Transpiration cooling involves the use of porous media, allowing the flowing fluid to absorb and evaporate heat, facilitating efficient heat transfer, which provides excellent cooling performance. In this study, porous metal was produced using a powder sintering process with nickel-based superalloy powder. To analyse the transpiration cooling performance depending on physical characteristics such as porosity, permeability, and pore size of the specimens, the physical property changes were examined based on the powder sintering process parameters, such as compaction pressure and sintering temperature. Subsequently, the transpiration cooling performance was evaluated.
