摘要:

2003年,首款激光等离子体微推力器(micro-Laser Plasma Thruster,μLPT)应用于美国空军微小卫星姿态轨道控制,激光微推进技术越来越受到业内人士的广泛关注。总结了激光微推进的五种工作模式,并进行了简要分析,重点关注了激光微推进技术发展过程中的靶特性研究现状,介绍了靶材物态和靶材结构两个方面的推进性能研究进展,并对其进行了分析,对激光微推进技术的进一步发展形成了一些认识和建议。

Abstract:

In 2003, the first micro-Laser Plasma Thruster (μLPT) is applied for the micro satellite orbit and posture control in Air Force. Laser micro propulsion technology has been paid more and more attention. There are five kinds of work modes summarized in this paper. The research of laser micro ablation of target, including the state and structure of target, is reviewed and analyzed. The further development of laser micro propulsion technology is discussed.
