Abstract

Based on pulsed laser propulsion, a set of system to measure pulse thrust with repeated loading was established. In the experiment, signals of pulse thrust are transformed into electric signals by PVDF (polyvinylidene fluoride) sensor. Then the electric signals were collected and displayed with data acquisition facility based on PCI controller. With the laser pulse rate of 10 Hz and pulse energy of 80J, the measurement was carried out. Two effective signals of pulse thrust were obtained. Experimental datum show that trend of variation of the first pulse thrust corresponds with that of the second one. The impulse coupling coefficient from the computation and measurements agree well, which indicates that the experimental set is reliable.
