Typical High-Temperature Seal Structur of Reusable and Hypersonic Vehicles
Abstract:
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.
