爆震发动机研究进展

Detonation is an important way to achieve pressurized combustion. Benefiting from the thermal efficiency gain of detonation cycle, the propulsion device based on detonation has significant theoretical performance advantages, which is expected to promote the leaping development of aerospace power technology. On the basis of summarizing the development of classical detonation theory and basic scientific issues related to detonation propulsion, this paper further introduces the research progress of low-order model establishing method of rotating detonation engine, as well as the performance analysis of turbo and ramjet rotating detonation engine, and summarizes the performance analysis and key problem research progress of oblique detonation engine. Finally, some research prospects on detonation engines are discussed based on the current research progresses.
