Research progress in micro-laser plasma propulsion
摘要
为了加快激光等离子体微推进技术(μLPP)在航天领域的应用, 介绍了该项技术近10年的发展状况。讨论了激光等离子体微推进技术发展过程中衍生出的各种工作模式, 并简略分析了不同工作模式的优缺点。着重介绍了靶特性对激光微推进性能的影响, 包括靶材的选择、靶的结构、靶材掺杂, 以及靶物相特性等。针对该项技术的最终发展目标是研制微小卫星姿轨控的激光等离子体微推力器( μLPT), 介绍并分析了美国Phipps小组开展的激光微推力器的研制工作。最后, 指出了激光等离子体微推进技术目前存在的一些问题, 并展望了它的发展前景。
Abstract
To achieve the applications of micro-Laser Plasma Propulsion(μLPP) to aerospace fields, the development of the μLPP technologies during 10 years was introduced. The different working modes for the μLPP were discussed and their advantages and disadvantages were analyzed briefly. The effects of laser micro ablation of a target on μLPP properties were also introduced, which involves the state of target, structure of target, doped target, and the liquid target. For the purpose of the micro satellite orbit and posture control, the micro-Laser Plasma Thrusters(μLPTs) developed by Phipps group in America were analyzed. Finally, the shortcomings in the research were pointed out and the further development of μLPP technology was given.
