航天飞机轨道器的热防护技术是航天飞机的关键性技术之一。本文介绍了美国第一代航天飞机轨道器所采用的非金属基复合材料热防护系统,美国宇航局兰利研究中心和Kentron国际公司共同设计的所谓近工艺品概念热防护系统,以及美国第二代航天飞机轨道器计划采用的防热系统与机壳融为一体的高级碳-碳复合材料热防护系统。 Space shuttle orbital thermal protection technology is one of the key technologies of the space shuttle. This article describes the non-metallic matrix composite thermal protection system used by the first generation of spacecraft orbiters in the United States, the so-called near concept heat protection system jointly designed by NASA Langley Research Center and Kentron International, and the second generation The Spacecraft Orbiter program uses a thermal carbon-carbon composite thermal protection system integrated with the enclosure to protect the system.
