整体式液体冲压发动机旋流燃烧室试验研究

AN EXPERIMENTAL INVESTIGATION OF THE SWIRLING COMBUSTOR FOR INTEGRAL LIQUID FUEL RAMJET

介绍了在燃烧室进口安置旋流室和火焰稳定器后,在增加燃烧稳定性和强化燃烧方面所取得的突破性进展。地面热试车的结果表明,旋流室与火焰稳定器相结合的结构方案,能够有效地消除低频燃烧振荡,提高燃烧效率。

In integral liquid fuel ramjet,the low frequency combustion oscillation is a very serious problem which greatly affects the normal operation of engine and fuel energy release .A great progress has been made in the enhancing of combustion stability and the improving of combustion process since the swirl ing chamber and flameholder was installed at combustor entrance. Ground hotting test results show that the combinative configuration of swirling chamber and flameholder can effectly eliminate the low frequency combustion oscillation and increase the combustion efficiency.
