Abstract

Cusped-field Hall thrusters (CFHT) have significant potential for use in many space missions due to their simplicity, long life and high efficiency. CFHT-27, designed and developed at the Bogazici University Space Technologies Laboratory (BUSTLab), is a prototype CFHT with a 27-mm diameter discharge channel. CFHT-27 utilizes samarium-cobalt (SmCo) permanent magnets. The thrust and efficiency of a cusped-field thruster is closely related to its size and design parameters. In this study, in order to understand the relationships between the design parameters and the thruster performance, the performance tests of the CFHT-27 are carried out for a given magnetic field topology. The thruster was operated at discharge voltages ranging from 250 to 500V with argon propellant with up to 3,000 s of specific impulse. The measurements show that CFHT-27 can achieve thrust values from 1 to 46 mN. Thus, this thruster can be used for a wide range of thrust values allowing throttle capabilities for different missions.

CFHT-27尖场霍尔推力器性能实验研究
Cusped-field Hall推进器(CFHT)由于其简单、寿命长和效率高,在许多空间任务中具有巨大的应用潜力。CFHT-27由Bogazici大学空间技术实验室(BUSTLab)设计和开发,是一种具有27毫米直径放电通道的CFHT原型。CFHT-27使用钐钴(SmCo)永磁体。尖头场推力器的推力和效率与其尺寸和设计参数密切相关。在本研究中,为了了解设计参数与推力器性能之间的关系,在给定磁场拓扑下对CFHT-27进行了性能测试。推力器在250 ~ 500V放电电压下工作,氩气推进剂比冲高达3000秒。测试结果表明,CFHT-27的推力值为1 ~ 46 mN。因此,这种推进器可以用于广泛的推力值,允许油门能力为不同的任务。
