水基推进系统综述

Study on the water-based propulsion system

水基推进系统的发展为航天器推进、供电、能量储存、系统构建提供了新的选择。这一系统的核心是一体化可再生燃料电池,它利用太阳能电池帆板提供的电能电解水,产生的氢氧气体既可以用于燃烧推进,又可以通过燃料电池反应重新复合为水进行供电。介绍了水基推进系统的基本组成与工作原理,通过质量估算与性能分析,评估了水基推进系统的工作能力、适用范围及空间应用优势。

Water-based propulsion system for advanced spacecraft applications has enabled new options for spacecraft propulsion, power, energy storage, and structure. At the heart of this system is a unitized regenerative fuel cell that uses electrical energy from the vehicle＇s solar array to convert water into its constituents of hydrogen and oxygen which can be burned to generate thrust or recombined to produce electric power. The components and the working principle of the water-based propulsion system are introduced. Through mass estimation and performance analysis, the work capacity of the water rocket and its application field are pointed.
