工质的选择对于激光推进任务的完成具有举足轻重的作用。液体工质以其自身独特的优点已经引起了国内外学者的浓厚兴趣。评述了国内外液体工质激光推进性能的研究进展,指出了研究工作中存在的突出问题,探讨了提高液体工质推进性能的可能途径,提出了将尺寸较小的水滴用作工质从而提高推进性能的方法。研究结果表明,液膜和尺寸较小的水滴是提高液体工质推进性能的有效途径。
The choice of working fluid for the completion of the task of laser propulsion plays a decisive role. Liquid working fluid with its own unique advantages has attracted the great interest of scholars at home and abroad. The progress of research on the laser propulsion performance of liquid working fluid at home and abroad is reviewed. The outstanding problems in the research work are pointed out. The possible ways to improve the propulsion performance of the liquid working fluid are discussed. The small size water drop is used as the working fluid to improve the working fluid. Promote the performance of the method. The results show that the liquid film and the smaller size of the droplet is an effective way to improve the propulsion performance of the liquid working fluid.
