Abstract
AbstractThe water-based propulsion system has the characteristics of green propellant and high specific impulse. The above characteristics make the propulsion system light in weight, high in integration, long in orbit life, easy to achieve on-orbit refueling. Consequently, it has a good space application prospect. Aiming at the mutual restriction between the configuration of water-based propulsion system and the requirements of space missions, a mathematical model for parameter optimization design of water-based propulsion system was established, the matching design of water-based propulsion system under different platform background applications was carried out and corresponding performance was given. Meanwhile, the effect of different design parameters on the design of the water-based propulsion system was carried out. Based on the research results, the space application of the water-based propulsion system was analyzed. Research shows that there is an optimal matching design point for the maximum number of days between missions, and there is an approximately proportional relationship between the weight and the scale of the water-based propulsion system. Therefore, the water-based propulsion system is more suitable for spaces with longer mission intervals and lighter payloads platform.
