Abstract本文对激光水下聚焦爆炸推进的作用机理开展了实验测量和数值模拟研究。实验观察到激光水下聚焦爆炸推进分为两个物理过程:(1)强激光与铝膜相互作用诱导等离子体演化,产生短脉冲、高幅值的等离子体压力,并对航行体做功;(2)激光爆炸产物气泡脉动,对航行体继续提供推力。另外,实验还对不同介质中的激光推进效率以及气泡与约束壁面/自由水面相互作用的物理机制进行了研究。发现在高阻抗环境介质、气泡受约束脉动以及近自由水面条件下,激光爆炸推进的效率更高。在实验的基础上,建立了激光水下聚焦爆炸推进的物理模型,发展了相应的耦合数值计算方法。计算得到的气泡脉动规律及航行体运动规律与实验测量结果一致,验证了计算的模型和方法...
