摘要
针对微纳卫星对推进系统高比冲、小功耗、结构简单、高集成度的应用需求,通过对微纳卫星水分解推进系统气液分离方案、供气方案、发动机设计等进行调研,得到了发水分解推进系统安全无毒无害、结构简单、功耗低、冲量精度高、比冲高,容易实现系统集成化。水分解推进系统可以充分利用星际原位水资源,在星际旅行、载人航天、应用卫星以及伴飞卫星等领域有较好的应用前景。
Micro-nano satellite requires the propulsion system to have high specific impulse,low power consumption,simple structure and high level of integration.The gas liquid separation solutions,the gas supply solutions and the engine design methods of water electrolysis propulsion system applied to micro-nano satellites were studied in this paper.And it was found that water electrolysis propulsion system has the characterises of safety,non-toxicity,simple structure,low power consumption,high impulse accuracy and high specific impulse,making it conductive to the realization of integration.The water electrolysis propulsion system could make full use of the in-situ water resources in outer space,and had a good application prospect in fields such as interstellar space travel,manned space flight,applied satellites and accompanying satellites.
