Abstract: Manned spacecraft hatch is the aisle for astronauts and cargo to enter and leave the sealed capsule of spacecraft. Once leakage occurs, it will affect the normal operation of manned spacecraft, and even threaten the life safety of astronauts. In order to ensure the sealing performance of manned spacecraft hatch, strict leak detection tests must be carried out before launching. In view of the special structure of manned spacecraft hatch, this paper mainly introduces the leak detection methods for hatch body and frame sealing ring, the whole hatch and the part of hatch. It forms a set of leak detection technology suitable for the whole development process of manned spacecraft hatch, which can meet the leak detection requirements of manned spacecraft hatch, such as Shenzhou spacecraft, space station, lunar module and so on.

Key words: manned spacecraft, hatch, leak detection technology
