研究领域
空间电推进技术气体放电及其应用

学术贡献：

空间动力技术是各国航天发展的战略重点，我国东方红-3B及东方红5号卫星平台已经对推进方式进行论证，常规化学推进方式无法满足15年的长寿命要求，必须采用电推进方案。我国已经在2012年和2016年两次进行霍尔电推进的空间搭载飞行试验，霍尔电推进取代化学推进已经成为航天动力发展的必然趋势。

磁场束缚电子碰撞而生成等离子体是霍尔推力器的工作介质，霍尔推力器放电过程中等离子体流动伴生的动态电磁场、放电不稳定性以及瞬态冲击等一系列暂态过程对霍尔电推进系统运行稳定性与性能有着重要的影响，是霍尔电推进空间应用的核心问题。

面向我国空间动力需求，围绕等离子放电应用过程中的暂态过程及其控制问题，发现霍尔推力器中一种新的等离子体振荡模式–励磁/放电耦合振荡；提出点火峰值电流理论边界预测方法和在轨点火裕度评价准则；提出放电低频振荡可镇定性理论并给出稳定条件，提出在轨低频振荡抑制与监测一体化设计方法。研究成果已经成功应用于我国首颗电推进卫星SJ-17上，并于2016年11月随长征五号首发星搭载在轨验证，并在多个预研型号中得到应用。

1. Matlab及其应用：秋季学期 24学时/年

MATLAB是适合多学科、多种工作平台的功能强大、界面友好、且开放性很强的大型优秀应用软件，同时也是国内外高等院校数学、数值分析、数学建模、数字信号处理、自动控制理论以及工程应用等课程的基本教学和实验仿真工具。本课程主要介绍了MATLAB的工作环境，基本操作指令、数据类型及图形的绘制功能、程序设计、GUI编程等方面的知识，课程以课堂讲解和软件操作实例说明MATLAB的实际操作和应用。本课程的目的是使学生熟练掌握MATLAB的基本功能和常用命令，并能够熟练地应用MATLAB解决相关课程学习中的复杂数学计算问题。

2. 等离子体推进导论：春季学期 40学时/年

霍尔推力器是一种为航天器在轨运行提供微小推力的动力装置，具有高效率、高比冲以及高可靠性等优点，广泛地应用于航天器的轨道提升、位置保持、姿态控制等推进任务。近年来， 随着大型卫星平台建设、微小卫星组网、深空探测等航天技术的不断发展，相应地对霍尔推力器的性能也提出了更高的要求，推动了其技术发展。在理论研究方面，虽然对推进器内部的各种物理机制进行了大量的理论和实验研究，但由于自身物理过程复杂且相互关联，仍有很多物理机制及其效应尚未彻底理解。本课程主要讨论涉及霍尔等离子体物理学基础、推力器设计及寿命、运行稳定性、空间应用等前沿物理问题，通过课程学习拓展研究生电推进物理科研思维和方法。
