摘要:
近年来,由于爆轰高效的燃烧方式,其已成为各国学者关注的焦点。而连续爆轰发动机只需一次点火,便能在燃烧室内形成连续传播的爆轰波,从而可以提供持续稳定高推力的优越性能使其成为航空推进的一个重要研究方向。本文基于北京大学燃烧推进动力中心的连续爆轰实验设备,利用H2/O2混合燃料,结合实验数据对连续爆轰发动机内部压力分布进行了实验研究,分析了连续爆轰形成、稳定和熄灭的过程,计算了实验中连续爆轰的速度和旋转周期,为进一步研究连续爆轰发动机内部机理奠定了基础。

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.
