| Abstract: |
| The continuous detonation engine(CDE) is a new concept engine, which is based on detonation waves to convert the chemical energy of the propellant into heat energy. It has been a focus for concern in the field of aerospace propulsion due to its inherent advantages. Recently, the detonation waves were obtained with various fuels and the flow field were understood further. The thrust and specific impulse initially measured demonstrated the performance advantages. Moreover, the CDE has operated successfully in the rocket, ramjet and turbo model. This shows the broad applicability of the CDE. In this paper, an overview of the development of the CDE is given from several aspects:operating principles,fundamental researches, applied researches, and so on. Representative results and outstanding contributions are summarized and the unresolved issues for further engineering applications of the CDE are discussed. |
