摘　　要：液体火箭发动机是宇航推进家族的重要成员 ,将会成为下一个历史时期使有效载荷达到第一宇宙速度的唯一推进手段 ,是制约航天发展速度的最关键因素。发展运载系统 ,动力必须先行。中国在 2 1世纪初必须推出能与世界先进国家相当的大型运载火箭。这些火箭不能建立在用原有的发动机增加数量以加大推力的基础上 ,必须研制单台推力更大、更先进、无污染的新型发动机 ,同时还需开展火箭航天飞机及其发动机使用的气动塞式喷管的预先研究 ,以火箭航天飞机为突破口 ,赶上世界先进水平。Liquid rocket engine is an important member of the space propulsion family and the only propelling means to bring payloads to the first universe velocity in the next historical period,which has vital effects on advancement of space technologies.Propulsion must enjoy priority in research and development of launch vehicles.In the early part of 21st century,China should successfully develop its heavy lift launch vehicles equivalent to that of other advanced countries in the world.We won't allow them to set up on the bases of simply increasing number and thrust magnitude of existent engines and must develop new types of engine which are more powerful,more advanced and without contamination.Meanwhile,we should begin preliminary researches on rocket spaceplane and aerospike nozzle adopted by it's propulsion.Along this way,we can finally catch up with the world's advanced level .
