“…The outer side of the tubular seal has through holes spaced 152.4 mm/each in the length direction, which allow the pressure of the seal to be released into the vacuum when the vehicle is in orbit. The hatch seal has to meet both the sealing requirements during re-entry and the ability to adapt to the external environment during orbit, and requires the intervention of the thermal protection system (TPS) of the flight orbiter throughout [11,12]. The hatch sealing structure contact surface is very much, mainly there are opposite hatch contact at the seal, the seal between the hatch and the bulkhead wall, the seal between the hatch and the beam directly, the seal of the direct expansion joint of the hatch components.…”

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

“…The level of deirradiation of sunlight by the Earth's surface and its atmosphere equals 240 W/m 2 . The real temperature of the frame surface in LEO can vary in wide diapason: 256 C 4 1 77 C [28], 290 C 4 1 120 C [29], 2100 C 4 1 200 C [30] and [22], and 2150 C 4 1 150 C [31].
