摘　　要：对空间液体推进系统的混合比调节技术进行了研究。根据闭环补气调节混合比原理,建立了补气调节混合比试验模型,研究了系统的流量特性。根据某同步轨道卫星平台推进系统的性能要求,给出了相应混合比的调节范围和对应的补气量,为混合比调节技术的实际工程应用提供了理论和试验依据。The technology of regulating the mixture ratio by injecting gas into each propellant tank along was studied in this paper. The regulating experiment system was established according to the principle of the mixture ratio by injecting gas into each propellant tank, and the flow characteristics of the system were studied by the experiment. According to the experiments data and the performance of some satellite propulsion system, the regulating range of mixture ratio was estimated. The study would supply academic and experimental foundation for engineering application.
