A Review of the Development of Sealing Materials and Measurement and Control Simulation Technology for Typical Hypersonic Vehicle Positions

Hypersonic vehicles are an important development direction in aerospace, and their will have a significant impact on world security, the of cosmic space resources related disciplines. Along with rapid modern aircraft, landing gear is commonly used retractable technology, which brings series problems, such as design hatch retraction heat sealing mechanism evaluation air tightness. This paper takes thermal structure front main vehicle example, reviews progress analysis techniques material properties for hypersonic at home abroad, discusses current status limitations outlines key technologies future trend, summarizes test equipment methods identifying performance seals systems.
