摘要
航天低温复合材料贮箱相比于传统的金属贮箱,减重可达20%~40%,为下一代低成本、高运载力、可回收航天器的研究开发提供了可能。通过对发展航天低温复合材料贮箱的必然性和其所具备的显著优势进行分析,从需求背景、结构参数、制造工艺等方面介绍了近30年来发达国家在该领域取得的成果以及存在的一些问题,针对这些问题提出了相应的解决方法,并对我国低温复合材料贮箱的发展与研究进行了展望。
Compared with the traditional metal tank,the space composite cryotank can achieve weight reductions up to 20%–40%,which provides the possibility for the research and development of the next generation of low-cost,highcapacity and recoverable spacecraft.The inevitability of the development of space composite cryotank is systematically analyzed.Furthermore,the achievements and problems in this field in developed countries during recent 30 years are introduced from the aspects of demand backgrounds,parameters of structures and processes of manufacturing,and some solutions to these problems are proposed.The development and research of composite cryotank in China are also prospected.
