An experimental study on phase-changed transpiration cooling performance of porous titanium alloy plates under high heat flux
2026
Overview
Hypersonic vehicles are subjected to extreme thermal environments with heat fluxes on the order of MW/m 2 during ascent and re-entry, posing significant challenges for thermal protection systems (TPS). Transpiration cooling, a bio-inspired active cooling method analogous to sweating, represents a highly efficient approach to TPS. This study experimentally investigates phase-change transpiration cooling using porous titanium alloy plates, aiming to elucidate the cooling mechanisms of titanium alloy/phase-change fluid systems under high heat flux conditions. An oxy-acetylene heating test platform was established to simulate megawatt-level thermal loads, and cooling experiments were subsequently conducted under heat fluxes of 1MW/m 2 and 2.5MW/m 2 . The results demonstrate that phase-change transpiration cooling provides excellent thermal protection. The front-side temperature of the sample remained stable between 200–300°C, while the back-side temperature did not exceed 60°C. This work provides key experimental data and theoretical support for the engineering application of porous titanium alloy/phase-change fluid transpiration cooling systems in the thermal protection of hypersonic vehicles.
