中国航天科技集团公司北京控制工程研究所完成了卫星在轨加注地面演示系统试验平台的搭建,成功进行了在轨加注接口对接、循环泵式流体传输、残液吹除、在轨加注接口分离等全过程地面演示试验。该演示试验是国内首个基于循环泵的卫星在轨加注全过程演示验证试验,标志着该研究所已初步掌握了卫星在轨加注关键技术。该研究所突破了微重力环境下
China Aerospace Science and Technology Corporation Beijing Institute of Control Engineering completed the satellite in-orbit ground demonstration system test platform set up, the successful in-orbit filling interface docking, circulating pump fluid transfer, raffinate blowing, in-line filling Interface, such as the whole process of ground demonstration test. The demonstration test is the first demonstration test of the whole course of satellite in-orbit filling based on circulating pump in China, which indicates that the institute has mastered the key technologies of in-orbit-filling of satellites. The Institute broke through the micro-gravity environment
