摘要
针对低温推进剂长期在轨贮存所面临的贮箱压力升高这一实际问题,热力排气系统(TVS)已被国内外研究学者认为是最具应用前景的贮箱控压方式。通过对国内外不同机构所开展的有关TVS方面的研究进行文献分析,重点梳理了低温贮箱TVS控压实验方面的发展脉络;对比分析了不同研究机构所开展的TVS工况设置与运行性能差异;提炼了TVS运行工作过程中的关键技术与相关结论。最后,基于低温推进剂在深空探测中大规模应用的需求,提出了中国在低温推进剂贮箱TVS压力调控方面的发展规划。
Cryogenic propellant usually experiences long-term on-orbit storage.The pressure increase in cryogenic storage tank is faced by most of space missions.The thermodynamic vent system(TVS)is treated as the promising method to control the increase of the tank pressure by scholars both at home and abroad.Based on the investigation conducted by different research agencies,literature review and management are conducted to reflect the recent research statue on TVS.The development profile of the experimental research on the pressure control performance of TVS is specially summarized.The condition setting and performance difference of TVS conducted by different agencies are compared and analyzed.The key technique and related conclusion are refined during the operation of TVS.Finally,based on the requirement of the large scale using of cryogenic propellant in deep space exploration in China,the development plan is proposed on the aspect of TVS pressure control on cryogenic storage tanks.
