摘要
激光烧蚀推进在微纳卫星发射、轨道机动等方面具有广泛的应用前景,其中聚合物掺混增强吸收的金属物质作为推进剂是激光烧蚀推进性能改进的重要方向。目前对脉冲激光烧蚀掺杂聚合物推力产生机理的研究手段主要集中于宏观推进性能的实验,数值模拟较少。为了拓展认识的范围,本文建立了激光烧蚀掺杂聚合物推力产生过程的模型,发展了一套完整包括激光能量沉积、工质烧蚀、烧蚀羽流飞散等过程的数值仿真程序。数值计算了3~40J/cm2激光烧蚀掺杂微米铝颗粒聚甲醛工质的烧蚀特性,比冲与实验数据保持一致,表明模型能够较好地模拟掺杂聚合物的动态烧蚀过程及羽流特性。获得了掺杂聚合物的推力时间变化曲线,并且用工质动态烧蚀过程及羽流场压强分布解释了激光烧蚀掺杂金属聚合物的推力产生过程,可为深入理解其推力产生机理,优化激光烧蚀推进性能提供参考。
