Abstract
To measure the propulsion characters of PVC(poly vinyl chloride) doped with carbon ablated by high power density laser, torsion pendulum is used to measure the micro impulse. Laser interference is used to detect the vibration of the pendulum which is caused by the ablating jet. The measurement error is 2.6 according to the calibration. Nd:YAG laser is used as the laser source. Mettler-Toledo XS105DU analytical balance is used to measure the ablated mass. The results indicate that the performance of PVC+2C is better as an alternate target. Both the specific impulse(Isp) and energy transforming efficiency() increase with laser power density(I0), while momentum coupling coefficient(Cm) decreases. The maximum measured Cm is 557N/W. Isp and reach to 204s and 46 respectively.
