摘　　要：场反构型洛伦兹力推力器利用旋转磁场驱动等离子体产生场反构型等离子体团(Filed Reversed Configuration-FRC),并利用洛伦兹力将其加速产生推力。由于该推力器不使用栅极加速,故不存在栅极溅射问题,大大延长推力器工作寿命。该技术借鉴自磁约束核聚变技术,推力密度大、功率扩展性好(MW级),在未来的深空探测和星际航行中具有广泛的应用前景。文章对场反构型洛伦兹力推力器发展现状进行了综述,并对工作原理、计算模型和技术瓶颈问题作了介绍,为中国等离子体推力器技术发展提供参考。Field reversed configuration Lorentz force propulsion technology uses a rotating magnetic field to drive plasma to generate field reversed configuration(FRC)and uses Lorentz force to accelerate it to generate thrust.Since this thruster does not use grid acceleration,there is no grid sputtering problem,which greatly extends the working life of the thruster.This technology draws on nuclear fusion technology,with high thrust density and a wide range of power levels,which is feasible for future deep space exploration for high specific impulse,high thrust and long-life propulsion systems.In this paper,the development of field reversed configuration Lorentz force propulsion technology is reviewed,and the working principle,calculation model and key problem are introduced.It provides a reference for plasma thruster technology in China.
