Research on Vacuum Fire Absorption Technology for Manned Spacecraft

At present, the fire extinguisher used in manned spacecraft has some problems that are difficult to solve. For example, the use of carbon dioxide in a narrow and closed environment has a great impact on the air quality of small space, and the medium after combustion in microgravity environment is scattered everywhere. The above problems can be solved by a kind of suction technology for negative pressure. In this paper, a vacuum lire suction experimental device is designed to meet the requirements of spacecraft lire suppression. The typical fire suppression process of spacecraft by vacuum lire suction technology is studied, which provides data support for the practical application of vacuum fire suction technology in manned spacecraft.
