Abstract

It is shown that the level of properties of a heat-shielding tile made of superthin quartz fiber and a silicate thermotacting coating for it exceeds that achieved during the creation of the Space Shuttle. The types of thermotactic coatings for the nose fairing of steel brazed honeycomb panels, flexible heat-resistant felt, and internal surfaces of the payload compartment are considered. It has been shown for the first time that the use of sublimable moisture FP-5182 protective fluorocopolymer varnish made it possible to significantly increase the emissivity of the heat-resistant antioxidant slip coating of the nose cone made of a material of the carbon–carbon system at temperatures above 400°C.

暴风雪号航天飞机的热致无机和聚合物涂层

摘要

结果表明，由超细石英纤维及其硅酸盐热敏涂层制成的隔热瓦的性能水平超过了航天飞机制造期间所达到的水平。考虑了钢钎焊蜂窝板机头整流罩、柔性耐热毡和有效载荷舱内表面的热致涂层类型。首次表明，使用可升华防潮FP-5182含氟共聚物保护清漆可以显着提高由碳-碳系统材料制成的鼻锥体耐热抗氧化滑爽涂层的发射率在 400°C 以上的温度下。
