摘要 为解决大型液体火箭发动机现有循环系统性能和技术难度及成本之间的矛盾,本研究基于低温推进剂液体火箭发动机工作环境特点,并结合磁流体发电机和直流超导电机的原理和工作特性,提出了一种不同于涡轮泵循环的超导电磁泵压循环系统。文中阐述了系统中超导电磁泵和磁流体发电装置的基本结构与工作原理,分析了系统的优缺点,并对超导电磁泵压循环系统进行了初步的可行性论证,最后对超导电磁泵压循环系统的应用前景进行了分析和论述。结论认为,作为一种全新的火箭发动机循环系统,超导电磁泵压循环系统具有非常广阔的发展及应用前景。 To resolve the conflict between performance and cost of propellant engine, magneto hydrodynamic (MHD) generator and direct current superconducting electrical machine principles and cryogenic liquid propellant rocket engines work environment characteristics has been combined, superconducting electromagnetic pump circulating system which is different from turbopump circulating system was put forward, Operating principles and the basic structure of superconducting electromagnetic pumps and MHD power devices which was used in system was expounded; the advantages and disadvantages of systems was analysis: preliminary feasibility of superconducting electromagnetic pump pressure circulating system was studied. In the end, the development and application prospects of the superconducting electromagnetic pumps circulating system was analysis and exposition. Concluded is that as a new rocket engine circulating system, the development and application prospects of superconducting electromagnetic pump circulatory system is very broad.
