为了研究连续旋转爆轰波的传播机理，采用斜缝式引射器结构，对切向安装H2/O2预爆轰管的H2/空气连续旋转爆轰发动机进行了实验研究。实验结果表明，当当量比为0.93时，可以成功地获得稳定的旋转爆轰波。旋转爆轰波的传播频率为5200 ~ 5500 Hz，传播速度为1518.5 ~ 1606.1 m/s。通过对旋转爆轰波传播机理的分析，验证了爆轰波的旋转、反转和分叉三种传播模式。
In order to study the propagation mechanism of continuous rotating detonation wave, the H2/air continuous rotating detonation engine ignited by tangentially installed H2/O2pre-detonation tube is studied experimentally using a tilt slot injector structure. The experimental results show that the stable rotating detonation wave can be gained successfully with the equivalent ratio of 0.93. The propagation frequency and velocity of rotating detonation wave range from 5200 to 5500 Hz and from 1518.5 to 1606.1 m/s, respectively. Three propagation modes, such as rotation, reversal and bifurcation, of detonation wave are verified through the analysis of propagation mechanism of rotating detonation wave.
