许多轻质热防护系统(TPS)材料具有很大程度的开放孔隙率，这使得它们对气体流动具有很高的渗透性。最近，建造了一种渗透率测量装置来测试刚性、多孔的TPS材料。本文介绍了用该装置制作的两种轻质陶瓷烧蚀材料，即酚醛碳烧蚀材料和硅浸渍可重复使用陶瓷烧蚀材料的气体渗透性。
Many lightweight thermal protection system (TPS) materials have a large degree of open porosity, which can make them highly permeable to gas flow. Recently, a permeability measurement apparatus was constructed to test rigid, porous TPS materials. This note presents further gas permeability, made with this apparatus, on two lightweight ceramic ablator materials; viz., phenolic impregnated carbon ablator and silicone impregnated reusable ceramic ablator
