Future application of combined cycle propulsion technology

Combined cycle propulsion combines two or more single types of power organically, with integrate each other in structure and complements each other in function, greatly expanding flight envelope and improving flight efficiency. It has important applications in near space hypersonic vehicle, reusable space transportation system and other fields. This paper introduces the basic classification and working principle of combined cycle propulsion, reviews the application of combined cycle propulsion technology in near space hypersonic vehicle and reusable space transportation system, and summarizes the development trend and main key technologies of combined cycle propulsion vehicle.
