A space rendezvous and docking device

Abstract

The invention relates to a space rendezvous docking assembly which comprises an anode assembly and a cathode assembly. The anode assembly is installed on a served spacecraft, the cathode assembly is installed on a serving spacecraft, the anode assembly is inserted into the cathode assembly and is locked by the cathode assembly, the safe and reliable rendezvous docking between the served spacecraft and the serving spacecraft is achieved, and thus different in-obit service tasks are completed.

Description

technical field [0001] The invention relates to a space rendezvous and docking device, in particular to a docking and docking device used between a satellite and a platform, and belongs to the technical field of space rendezvous and docking. Background technique [0002] With the advancement of space technology, the number of satellites and spacecraft launched every year around the world is increasing, and the diversity and complexity of space work are also increasing rapidly, so the demand for extravehicular activities is also increasing. For example, the capture, maintenance, fuel replenishment and module replacement of in-orbit spacecraft, as well as scientific experiments on the outer space environment, and extravehicular activities such as cleaning up space junk. [0003] It turns out that these tasks are mainly completed by astronauts, but these extravehicular activities will be subject to many restrictions: first, the strength and scope of work of astronauts are limit...

Problems solved by technology

[0003] It turns out that these tasks are mainly completed by astronauts, but these extravehicular activities will be subject to many restrictions: first, the strength and scope of work of astronauts are limited, and they cannot do anything about the installation of large-scale aerospace equipment (such as space stations); second, due to oxygen supply and There are dangerous reasons such as radiation in outer space, and the continuous working time of astronauts outside the cabin is limited; in addition, due to the existence of microgravity, high vacuum, strong radiation and tiny planetary bodies in space, it is difficult for astronauts to perform various operations in the space environment. It is very difficult and dangerous; at the same time, in order to support the extravehicular activities of astronauts, a huge and complex environmental control system and life support system are required, which will inevitably bring huge expenses.
