一种发汗冷却热防护试验系统
By installing armored thermocouples to control the steam solenoid valve inside the test chamber, the liquid is kept at a constant temperature and pressure. This solves the problem of the contradiction between permeability and strength in the thermal protection material of hypersonic vehicles during the sweating and cooling process, and enables the material to operate stably at high temperatures.

AI Technical Summary
In the process of sweating and cooling, the thermal protection materials of existing hypersonic vehicles have a contradiction between permeability and strength, which leads to long liquid retention time and easy vaporization and pressure increase at high temperatures, damaging the materials and cavities.
By installing armored thermocouples inside the test chamber to measure the liquid temperature, and using the feedback signal to control the opening and closing of the steam solenoid valve, the liquid inside the chamber is kept at a constant temperature and pressure, thus extending the thermal protection time.
It has enabled the stable operation of thermal protection materials under high temperature and high pressure environments, avoiding material damage caused by liquid vaporization and extending the thermal protection time.
