| 摘要: |
| 在成功研制液体工质注入系统的基础上,以脉冲式CO2激光器为光源,将雾化水滴用作工质,进行了激光推进性能实验测试研究。实验发现水工质激光推进冲量耦合系数较大气吸气模式获得了较为明显的提高,达到了50×10-5N.s.J-1左右。与国内外相关实验结果进行了对比分析,讨论了提高液体工质激光推进性能参数的方法。 |

| Abstract: |
| A CO2 laser was employed to ablate water droplets provided by a pulsed liquid propellant feeding system.Experimental results indicate that momentum coupling coefficient Cm is increased to 50×10-5N·s·J-1,which is higher than that of air-breathing mode laser propulsion.The measurement data were compared to the results of other authors.The way to improve the performance parameters of laser propulsion with liquid propellants was discussed. |
