摘　　要：基于PIC-MCC算法,自主开发了功能模块化的数值模拟平台(HD-HER),数值模拟研究了霍尔推进系统的放电特性。得到放电过程中电子和离子在通道内外的分布、离子速度和推力。研究结果与PSAC实验室结果吻合较好,为霍尔推进系统的改进和优化提供理论指导。Based on PIC-MCC algorithm,a functional modular numerical simulation platform(HD-HER)was developed and the discharge characteristics of Hall propulsion system were studied numerically.The distribution of electrons and ions inside and outside the discharge channel,ion velocity and thrust are obtained.The experimental results are in good agreement with those experimental results of PSAC laboratory,which provides theoretical guidance for the improvement and optimization of Hall propulsion system.
