安装在卫星上的霍尔推力器工作时喷出的高速束流会对卫星太阳电池阵列产生溅射,卫星太阳电池阵列溅射产物返回至卫星敏感区对敏感设备产生沉积污染。本文建立了兰州空间技术物理研究所LHT-100霍尔推力器的束流模型,应用LHT-100霍尔推力器束流模型计算了霍尔推力器的束流分布和束流发散半角。并结合该束流模型建立了卫星敏感区沉积模型,计算了安装在卫星上的LHT-100霍尔推力器束流在卫星敏感区域的沉积率,对敏感器在卫星上的安装布局提供重要的理论指导,同时也为LHT-100霍尔推力器在卫星上的安装倾角提供理论依据。
The high-speed beam emitted by the Hall thruster installed on the satellite will cause the sputtering of the satellite solar array, and the sputtered products of the satellite solar array return to the satellite-sensitive area to cause deposition pollution to the sensitive equipment. In this paper, the beam model of LHT-100 Hall thruster is established. The LHT-100 Hall thruster beam model is used to calculate the beam current distribution and beam divergence half-angle of Hall thruster. The model of satellite sensitive area deposition is established based on the beam model. The deposition rate of the LHT-100 Hall thruster beam installed on the satellite in the satellite sensitive area is calculated, which provides important information for the installation of the sensor on the satellite Theoretical guidance, but also for the LHT-100 Hall thruster on the installation of satellite tilt provide a theoretical basis.
