Combined cycle propulsion technology is an organic combination of multiple propulsion technologies from the aspects of thermal cycle, structural configuration and so on, which has the characteristics of wide flight envelope and better comprehensive performance. In this paper we summarize the development history of foreign combined cycle engines, then introduce several mainstream typical combined cycle engines. We also discuss and summarize the development trend and key technologies of combined cycle propulsion technology. Finally we propose some suggestions for technology development.
