深空探测、在轨服务和载人登月等国家重大空间任务对发展具有大功率、高比冲和长寿命的空间推进技术提出了迫切需求。FRC电磁推力器是一种可运行在超高功率水平且具有优良性能的新型电磁推力器。目前研究面临的首要问题是推力器工作中能量损失严重，造成推力器性能偏低。本项目根据等离子体放电理论和磁流体动力理论，采用数值计算、分子动力学模拟和实验研究相结合的方法重点开展RMF天线与等离子体的能量耦合研究和磁约束等离子体的能量耗散研究。掌握RMF天线与等离子体的能量耦合机理和磁约束等离子团的能量转移和耗散机理，从根本上突破能量高效耦合和耗散抑制技术。本项目的研究成果能为FRC电磁推力器的性能优化提供理论和技术支撑，对推动我国空间探测能力的提升具有重大科学意义。

Major national space programs, such as deep space exploration, in-orbit service and manned lunar landing, require the development of space propulsion technology with high power, high specific impulse, and long lifetime. Field Reversed Configuration (FRC) Electromagnetic thruster is a new type of electromagnetic thruster which can operate at ultra-high power level with excellent performance. At present, the primary problem of the research is the serious energy loss of the thruster, which leads to the low performance of the thruster. Based on the plasma discharge theory and magnetohydrodynamic theory, this project focuses on the energy coupling research between RMF antenna and plasma, and the energy dissipation research of magnetically constrained plasma by combining numerical simulation, molecular dynamics simulation and experimental research. Master the energy coupling mechanism between RMF antenna and plasma as well as the energy transfer and dissipation mechanism of magnetically constrained plasmoid, and fundamentally break through the energy efficient coupling and dissipation suppression technology. The research results of this project can provide theoretical and technical support for the performance optimization of the FRC thruster, which is of great scientific significance for the national space exploration capability.
