无电极洛伦兹力推力器技术发展研究

近年来,为了适应深空探测、载人航天、航天器在轨服务等空间任务的需求,大推力、高比冲、长寿命、高推力密度的高功率电推进技术吸引了众多学者的持续关注.相比于其他类型的高功率电推进技术,无电极洛伦兹力推力器(ELF)在推力密度、推重比等指标上具有明显优势,且从原理上克服了电极烧蚀对高功率电推力器寿命的制约,具有广阔的应用前景...

Development of Electrodeless Lorentz Force Thruster

In recent years, in order to meet the needs of space missions such as deep space exploration, manned spaceflight and on orbit service of spacecraft, the high power electric propulsion technology with high thrust, high specific impulse, long lifetime and high thrust density has attracted the continuous attention of many scholars. Compared with other types of high power electric propulsion technologies, Electrodeless Lorentz Force (ELF) has obvious advantages in thrust density, thrust to weight ratio and overcomes the restriction of electrode erosion on the lifetime of high power electric thrusts. According to the research status of high power electric propulsion equipment, this paper compares the similarities and differences of the technical approaches in the development process of the ELF thruster, introduces the development of each component in detail, analyzes the problems encountered in the research process, and puts forward the key research directions of ELF thrusters in the future.
