摘要: 为了研究圆柱形阳极层霍尔推力器运行过程中的轮辐效应〖BF〗(〖BFQ〗rotatingspoke〖BF〗)〖BFQ〗旋转频率在相关工作参数影响下的变化规律,找出抑制轮辐效应的方法,采用了将环形阳极分成独立两段的设计方案,通过观测两个独立阳极段之间的信号随放电电压、工质输送速率等参数的变化来定性定量开展试验研究。试验观测结果表明,该推力器在运行过程中,随着放电电压和气压的增加,轮辐效应旋转频率相应地获得提高;在近阳极区域的轮辐效应是普遍存在的,即使是在高电压的条件下;轮辐效应旋转频率主要在10~45kHz;轴向电流振荡在独立阳极段总电流中约占50%。减小工质流量,降低放电电压有利于抑制轮辐效应。
