Space station water-based propulsion system based on hydrogen arc thruster and hydrogen-oxygen engine

Abstract

The invention relates to a space station aqueous-based propulsion system based on a hydrogen arc thruster and a hydrogen oxygen engine. The space station aqueous-based propulsion system comprises a waste water processing and electrolyzing module (1), a hydrogen-oxygen storage module (2), a hydrogen-oxygen supplying module (3), a hydrogen arc thrustor module (4) and a hydrogen-oxygen engine module (5). The space station aqueous-based propulsion system disclosed by the invention meets two requirements that exhaust gas and waste water are effectively processed in a manned space station and propellants are saved, and besides, the hudrogen arc thrustor module (4) is led for adjusting the proportion of oxygen to hydrogen, which are consumed by the whole system, so that the defect that a conventional aqueous-based propulsion system is difficult to completely and effectively utilize the oxygen and the hydrogen of which the mixing ratio of the oxygen to the hydrogen being 4 or less, which are generated by exhaust gas and waste water in the conventional space station, is overcome, the effective utilization of the exhaust gas and the waste water of the space station is realized, and 25% or more of the propellants can be saved for the space station each year.

Description

technical field [0001] The invention relates to a space station propulsion system, in particular to a space station water-based propulsion system based on a hydrogen arc thruster and a hydrogen-oxygen engine. Background technique [0002] The space station is the largest spacecraft under development in China. It has a large windward area and operates in a low orbit. In order to overcome the atmospheric resistance of outer space and maintain the orbital altitude, it needs to consume a large amount of propellant. The satellite propulsion system of the existing space station follows the traditional dual-component propulsion system based on methylhydrazine / nitrogen tetroxide, which needs more than 3000kg of propellant for the normal operation of the space station every year. [0003] At the same time, in order to provide the long-term on-orbit astronauts with the necessary water and oxygen for survival, the space station electrolyzes water through the water electrolysis system t...

Problems solved by technology

At present, during the operation of the space station, a large amount of domestic waste water and electrolytic waste gas (hydrogen gas) will be generated. These waste water and waste gas are not only difficult to use, but also need to consume additional resources to treat and discharge them.

[0004] In order to solve the problems of huge consumption of propellant in the orbital operation of the space station and the difficulty in effectively utilizing the waste gas and waste water of the space station, it is necessary to propose a propulsion system that can efficiently use hydrogen and oxygen gas to generate thrust
