| 摘要: |
| 以基于N2O/C7H8的燃烧驱动混合型气动CO2激光器点火试验为研究背景，设计了液态N2O供应系统及N2O/C7H8单喷嘴燃气发生器。对液态N2O供应系统、N2O/C7H8的点火及燃烧性能进行了研究。试验结果表明：设计的N2O供应系统能够实现液态N2O的稳定供应；在设定的时序下，两个设计工况(余氧系数分别为0.3和0.4)均能顺利点火，燃烧室压力平稳；随着余氧系数的增加，燃烧效率明显提高。 |

| Abstract: |
| In order to carry out ignition experiment on combustion-driven mixing gasdynamic CO2 laser based on N2O/C7H8, a liquid N2O supply system and a N2O/C7H8 mono-injector gas generator were designed. The liquid N2O supply system, ignition and combustion performances of N2O/C7H8 were studied. Experimental results indicate that N2O can be supplied in liquid state by the designed liquid N2O supply system; ignition can be realized under two operating modes(excess oxidizer coefficient is 0.3 or 0.4) in designed time sequence and the combustor pressure is smooth. In addition, with the increase of excess oxidizer coefficient, combustion efficiency improves obviously. |
