飞行器典型热密封结构

摘要

Reusable and hypersonic vehicles pose an extraordinary challenge for seal structures. Airframes and engines require lightweight, high-temperature seal structural that can withstand the extreme environment of hypersonic flight. This paper reviews relevant seal technology for typical vehicles (e. g. Space Shuttle, X-38 and X-51) and presents several seal technologies for future hypersonic vehicles, foucs on high-temperature seal structural of the space shuttle TPS, vehicle penetrations and control surfaces.%对航天飞机、X-38和X-51等飞行器的热密封结构进行了综合评述.分析了机身TPS、机身开口部位及控制面三个安装部位的热密封结构特点,综述了其热密封组件的研究历程和使用现状.
