【摘要】 设计并加工了激光推进器实验模型,以空气为推进工质,利用脉冲式CO2激光器,研究了空气压强对激光推进器冲量耦合系数影响。实验结果表明,空气压强对激光推进器性能有显著影响。在文中实验条件下,当空气压强大于6 kPa时,激光推进器冲量耦合系数随压强减小而减少较慢;当空气压强小于6 kPa时,激光推进器冲量耦合系数随压强减小而减少很快。更多还原

【Abstract】 The experimental model of laser thruster was designed and made.Taking air as propulsion medium,the effect of pressure on impulse coupling coefficient of laser thruster was investigated by using impulse-ype carbon dioxide laser.The emperimental results show that pressure has significant effect on impulse coupling coefficient of laser thruster.Under the given emperimental condition,when pressure is more than 6 kPa,impulse coupling coefficient of laser thruster decreases slowly with the decrease of pressure;when pressure is less than 6 kPa,impulse coupling coefficient decreases fast with the decrease of pressure.更多还原
