摘要:Abstract: In recent years, detonation has become a hot topic of scientific research because of its high combustion efficiency. Continuous detonation engine will be able to form continuous propagation of detonation in the combustion chamber needing only once ignition, which can provide stable high thrust, and becomes an important research direction of aviation propulsion. Based on the continuous detonation experimental equipment of the Center of Combustion and Propulsion Power, Peking University, combined with the experimental data, internal pressure distribution of the continuous detonation engine is studied and the formation, stabilization and annihilation of the continuous detonation are analyzed. Also, the velocity and period of continuous detonation are calculated. All the works lay the foundation for further study of the internal mechanism of continuous detonation engine.
