| Abstract: | The performance improvement of liquid apogee engine （LAE） can create enormous eco- nomic and social benefits. The maximum specific impulse of foreign N204/MMH LAE with high-per-formance injector, efficient combustion chamber and new type high-temperature resistant material is up to 323 s. In this paper, the characteristics and key technologies of the high-performance LAE abroad are analyzed and the development of the Third Generation 490 N engine in china is intro- duced. According to the engineering need and the development status of the engine, the research focus of the Third Generation 490 N engine is put forward. |
