Turbine based combined cycle engine will be the main power device of future hypersonic aircraft. It can meet the requirements of space transportation, high-speed transportation and long-distance rapid strike. It has the advantages of conventional take-off and landing, repeated uses and good economy. This paper reviews the development of key technologies of turbine-based combined cycle power in many aviation powers, and analyzes the key technical bottlenecks that must be solved in the research of turbine based combined cycle engine technology including mode transition, aircraft and engine integration, ultrawide operating range, high temperature resistance, compatibility and so on. Combined with the advanced experience of foreign countries, the paper expounds the development prospects and suggestions of domestic turbine based combined cycle engine research, and summarizes the key technical problems of turbine based combined cycle engines that must be solved.
