空间机动服务平台在轨补给技术研究

Research on On-Orbit Refueling of Maneuverable Platform

根据空间机动服务平台的特点,对推进剂在轨补给技术进行了研究,提出了一种空间机动平台推进剂在轨补给方案,即基于表面张力贮箱作为加注箱和接受箱的双组元推进系统的在轨加注方案。该方案具有如下优点:与现有卫星推进系统相匹配,改动量最少;没有使用任何活动部件,提高了系统的可靠性;产生的热量比倍压式要少,便于缩短加注时间,提高加注的可靠性和安全性。依据这一方案对空间机动平台在轨补给系统进行了详细设计。

In view of the characteristics of maneuverable platform, the research on the maneuverable platform refueling on-orbit, which fits to bipropellant systems, is carried out. In the scheme, the surface tension tanks are used as supported and received tanks. The advantages of the scheme are as follows, Firstly, the scheme is matched with the propulsion system of spacecraft in China Secondly, no moving assemblies are used in the scheme, so the reliability of the system can be improved. Thirdly, the surface tension tank is the most appropriate tank for refueling spacecraft on-orbit. In the paper, system of the maneuverable platform is designed in detail.
