The invention provides an anhydrous hydrazine and green dinitrogen tetroxide dual-mode propelling system which is characterized in that a first output end of a gas path pressurization module is connected with an oxidant storage box module, and a second output end of the gas path pressurization module is connected with a fuel storage box module; the output end of the oxidant storage box module and the output end of the fuel storage box module are both connected with a dual-mode 490N engine in the apogee orbital transfer module; and the output end of the apogee orbital transfer module is connected with the attitude control module. According to the dual-mode propelling system, the advantage of high specific impulse of a dual component and the advantages of high reliability and small thrust of a single component are fully utilized; and compared with a unified double-component propelling system, the system is lighter in dry weight, meanwhile, the utilization rate of a single-component propellant is high, an oxidizing agent can be exhausted, and the unavailable amount of the propellant is small. In addition, the volumes of the oxidant fuel storage tanks of the dual-mode propulsion system adopting the three-storage-tank scheme are close, the height of a satellite bearing cylinder can be effectively reduced, and the constraint of the overall layout of the satellite and the lightweight design requirement of the system are better met.

    本发明提供了一种无水肼与绿色四氧化二氮双模式推进系统,包括:气路增压模块的第一输出端与氧化剂贮箱模块连接,第二输出端与燃料贮箱模块连接;氧化剂贮箱模块的输出端和燃料贮箱模块的输出端均与远地点变轨模块中的双模式490N发动机连接;远地点变轨模块输出端和姿态控制模块连接。本发明的双模式推进系统充分利用了双组元高比冲优点和单组元高可靠、推力小的优点;且与统一双组元推进系统相比,系统干重更轻,同时单组元推进剂利用率高,可以将氧化剂耗尽,推进剂不可用量少。此外,采用三贮箱方案的双模式推进系统氧化剂燃料贮箱容积接近,可以有效降低卫星承力筒的高度,更加符合卫星总体布局的约束和系统轻质化设计要求。
