To provide a simple and light air flow transpiration cooling system with high heat-resistance, having extremely high heat flux and atmosphere gas with an oxidization/reduction property, and capable of materializing suitable gas blow-out even under an environment where atmosphere gas pressure and the heat flux are spatially changed, in a heat-resisting system of a method making gas uniformly blow out from a surface of heatproof material made from porous ceramic.
In the air flow transpiration wide area heat protecting system using the inclining porous ceramic composite material 1, a fiber reinforcing porous ceramic composite material incliningly adjusted in porosity and/or thickness is joined with base material to structure a heatproof wall corresponding to outside air flow pressure and a heat flux distribution. Pressurizing coolant is supplied from a back surface to ooze from the heatproof wall into the outside air, thereby forming a cooling system element. Fiber material improving the toughness if the porous ceramic by fiber reinforcement is combined by tilting a fiber containing rate in a wall thickness direction.
