摘要
综述了近10 年来国内外液体靶材激光推进的主要研究成果。分析了液体靶材激光推进的一般机理,得出了溅射是液体靶材推进性能主要制约因素的结论。提出了改变靶材结构形态和增大靶材黏度从而改善推进性能的两种有效途径,依据不同途径依次评述了体状、膜状、滴状和高黏度液体靶材的性能特点,并总结出了己烷炮靶、雾化水滴和高黏度溶液这三种综合推进性能较好的液体靶材。最后指出了复合靶材将成为未来液体靶材激光推进的一个重要发展方向。
Abstract
The main research results in recent ten years of laser propulsion with liquid propellants are summarized internally and internationally. The general mechanism of laser propulsion with liquid propellants is analyzed. And the splashing is concluded as the most important constraint of the performance of liquid propellants. Changing the geometries of propellants and increasing the viscosity of liquid are presented as two effective ways to improve propulsive performance. And the performance characteristics of liquid volume, thin film, droplet and highly viscous propellants are commented successively based on the different ways. The hexane film, water droplet and highly viscous solutions are concluded as three kinds of liquid propellants with better integrated propulsive performance. Finally the compound propellant is pointed out to be one of the most important future directions of laser propulsion with liquid propellants.
