| 1 | The View of Micropropulsion Technology for China’s Advanced Small Platforms in Deep Space显示文摘In this paper,micropropulsion systems are analyzed in conjunction with the various mission requirements of China’s deep space exploration.As a great challenge facing the world,deep space exploration can be enabled only in a few countries with a success rate of around 50%.With the advancement of spacecraft and scientific instruments,it is now feasible to build small and low-cost spacecraft for a variety of deep space missions.As spacecraft become smaller,there is a need for proper micropropulsion systems.Examples of propulsion system selections for deep space exploration are discussed with a focus on products developed by Beijing Institute of Control Engineering(BICE).The requirements for propulsion systems are different in lunar/interplanetary exploration and gravitational wave detection.Chemical propulsion is selected for fast orbit transfer and electric propulsion for increasing scientific payloads.Cold gas propulsion and microelectric propulsion are good choices for space-based gravitational wave detection due to the capability of variable thrust output at the micro-Newton level.The paper also introduces the sub-1-U micropropulsion modules developed by BICE with satisfactory performance in flight tests,which are promising propulsion systems for small deep space platforms.A small probe with an electric sail propulsion system has been proposed for the future solar system boundary exploration of China.The electric sail serves as not only a propellant-free thruster but also a detector probing the properties of the space medium. | Yanming Wei Hao Yan Xuhui Liu Yang Yu Jinyue Geng Tao Chen Tuoqu Fu Gaoshi Su Yu Hu Daoman Han | 2022 | Space(Science & Technology)2022，，1： | 0 |
