Design of vacuum support system for manned spacecraft

One of the main tasks of manned spacecraft is to conduct space science experiments. The vacuum support system of manned spacecraft provides support for exhaust emissions and vacuum maintenance in space science experiments. The article first conducted a survey on the development and application of vacuum support technology for the International Space Station, and conducted an in-depth analysis of the demand for load vacuum extraction and exhaust emissions in China's manned spacecraft applications. On this basis, the design of the vacuum support system for China's manned spacecraft was carried out, and the ground verification test of the vacuum support system was completed. The in orbit application plan and task execution status of the vacuum support system for China's manned spacecraft were proposed.
