| 摘要: |
| 为获得脉冲激光能量对含能液态工质推进性能的影响规律，通过基于激光器、高速相机、扭摆搭建的测试系统对二硝酰胺铵（ADN）基液体工质的吸收性能、烧蚀性能、推进性能进行了研究。结果表明：ADN基含能液体是一种理想的液体工质，吸收系数达354.05cm-1，吸收深度为28.24μm。在0~63.97mJ能量范围内，增大激光能量有利于提高ADN基液体工质的推进性能。在激光能量为63.97mJ时，ADN基液体工质的推进性能达到最优，对应的推进性能参数分别为：冲量53.31μN·s，冲量耦合系数0.8757mN·s·J-1，比冲281.59s，能量转化效率122.40%。 |

| Abstract: |
| In order to study the effects of the pulsed laser energy on the propulsion performance of liquid propellant，the absorption performance， ablation performance and propulsion performance of the ammonium dinitramide （ADN）-based propellant were tested by the systems based on laser， high-speed camera and torsion pendulum. The experimental results show that the ADN-based propellant is an ideal liquid working medium， with an absorption coefficient of 354.05cm-1 and an absorption depth of 28.24μm. In the energy range of 0~63.97mJ， laser energy is beneficial to improving the propulsion performance of ADN-based propellant.When the laser energy is 63.97mJ， the propulsion performance of ADN-based propellant reaches the best，with an impulse of 53.31μN·s， an impulse coupling coefficient of 0.8757mN·s·J-1， a specific impulse of 281.59s and an energy conversion efficiency of 122.40%. |
