Abstract

The invention provides a cabin door structure and aerospace equipment with the same. The cabin door structure of the aerospace equipment is used for mounting a cabin door on a cabin and comprises a holding portion, mounting tables, self-destruction connecting devices and a split connecting device. The holding portion is arranged on the cabin door, the mounting tables are arranged on two opposite sides of the cabin, the self-destruction connecting devices are connected with the cabin door and the mounting tables, and the split connecting device is connected with the cabin door and the mounting tables. The cabin door structure and the aerospace equipment have the advantages that the cabin door structure can guarantee that the cabin door of the aerospace equipment can be tightly locked to be closely connected with the cabin in a launch procedure and a cabin door system can bear violent impact loads at a launch phase; the cabin door can be easily opened during in-orbit maintenance, and can be easily closed and connected with the cabin after a maintenance procedure is completed.

Description

technical field [0001] The invention relates to a cabin door structure, in particular to a cabin door structure of aerospace equipment, and to aerospace equipment with the cabin door structure. Background technique [0002] Spacecraft on-orbit service technology has emerged since the 1960s, and can be divided into manned on-orbit service and autonomous on-orbit service according to the type of service body. Manned in-orbit service mainly uses astronauts to maintain space equipment, and the design of the hatch is relatively low. For example, the Hubble Space Telescope uses a common hatch structure. When repairing, the astronauts only need to push and pull. The opening and closing of the cabin door, etc., thereby maintaining the aerospace equipment, but there are various disadvantages such as high cost and high risk in the manned on-orbit service. Autonomous on-orbit service mainly uses space manipulators to perform on-orbit maintenance and replacement of aerospace equipment....
