| Summary: | In order to study the rotational detonation characteristics of rich combustion gas in solid ramjet engines, this paper replaces solid rich combustion gas with CH4/CO/H2 mixture as fuel and uses ambient temperature air as oxidant to investigate the propagation characteristics of rotational detonation waves in the mixture. The experimental research results show that a mixture mass ratio of 1∶4.4∶0.67, a mass flow rate of 54.5 g/s, and an air mass flow rate ranging from 370.9 g/s to 782.3 g/s can detonate and form stable rotating detonation waves. With the increase of air flow, the propagation mode of rotating detonation undergoes a process of single wave, double wave collision to four wave collision. The propagation speed of the detonation wave showed a change of first increasing and then decreasing. When the air mass flow rate is 484.9 g/s and the equivalence ratio is 0.95, the maximum detonation velocity is 1 167.8 m/s. |
