The invention relates to the technical field of single-component propulsion systems of satellite constellations and internet satellites, and provides an additive manufacturing lightweight modular single-component propulsion system based on SLM forming, which comprises a piston storage tank, a gas adding and discharging valve, a liquid adding and discharging valve, a pressure sensor, a filter, a first electromagnetic valve, a second electromagnetic valve, a single-component thrust chamber and a plug, the gas charging and discharging valve, the liquid charging and discharging valve, the pressure sensor, the filter, the first electromagnetic valve, the second electromagnetic valve, the single-component thrust chamber and the plug are respectively connected to the bottom of the piston storage tank; the piston storage box comprises a storage box shell, a storage box piston and a shell end socket, the storage box shell is of a follow-up fine flow channel thin-wall bearing structure, the storage box piston is arranged in an inner cavity of the storage box shell and is in dynamic seal with the storage box shell through a double-O-shaped ring, and the end of the storage box shell is fixedly connected with the shell end socket. The conventional assembly and conduit connection mode of the propulsion system is simplified, a distributed configuration is avoided, conduits and supports are reduced, and assembly welding of the conduits is canceled.

    本发明提供了一种涉及卫星星座和互联网卫星的单组元推进系统技术领域的基于SLM成形的增材制造轻质模块化单组元推进系统,包括:活塞贮箱、气加排阀、液加排阀、压力传感器、过滤器、第一电磁阀、第二电磁阀、单组元推力室以及堵头,气加排阀、液加排阀、压力传感器、过滤器、第一电磁阀、第二电磁阀、单组元推力室以及堵头分别连接在活塞贮箱底部;活塞贮箱包括贮箱壳体、贮箱活塞以及壳体封头,贮箱壳体为随形精细流道薄壁承载结构,贮箱壳体内腔中设有贮箱活塞,贮箱活塞通过双O形圈与贮箱壳体动密封,贮箱壳体端部固连有壳体封头。本发明简化推进系统常规组件及导管连接方式,避免分散式构型,减少导管和支架,取消导管的装配焊接。
