摘要:

根据美国对ＳＳＭＥ和ＳＴＭＥ的改进设计以及前苏联、欧洲和日本分别对ＲＤ－０１２０、Ｖｕｌｃａｉｎ和ＬＥ－７发动机的开发研究，探讨在研制未来大推力液体火箭发动机（ＬＲＭ）中各国的指导思想和设计原则，分析世界在这一领域的发展动向。

Abstract:

n recent years, the space shuttle main engine (SSME) and the spacetransportation main engine (STME) have been improved in the U. S. A., in addition, the RD-170, Vulcain and LE-7 LRM have respectively been developed by theformer Soviet Union, Europe and Japan. According to these improvements and developments, this paper would inquire into the guide thinkings and design principlesof the various countries in the developments of the future large-scale LRM, andthen analyse the world’s new development trend in this field.
