Abstract:This paper provides a new thermal protection method, heat balance thermal protection, which is adaptable for thermal protection of hypersonic vehicle. Its principal theory is thermal equilibrium isothermal mechanism. By using heat balance thermal protection the temperature of thermal protection layer turns into equality. Systematic research has been done directly about heat balance thermal protection, including principle, analytical methods of the theory and key techniques. It is shown that the temperature and heat stress can be cut down effectively by the heat balance thermal protection. The heat balance thermal protection is effective in non ablating thermal protection of hypersonic vehicle.
Keywords:Heat balance thermal protection  Non ablating thermal protection  Hypersonic vehicle
