摘要: 为探索放电室能量损耗机制，开展了离子推力器放电室能量平衡研究。基于放电室零维模型，得到放电室电流平衡关系，结合放电室电势分布，分析放电室能量损耗并建立了能量平衡模型。应用模型计算LIPS200离子推力器放电室各项能量损耗，并进一步得到各能量损耗所占比例，所得结果与国外离子推力器NEXT具有较好的一致性；采用多工况试验参数（阳极电流4.0~4.4 A，阳极电压34~38 V）对放电室总能量损耗进行动态验证，结果表明：计算结果与试验结果误差小于3%。Abstract: To get the mechanism of energy loss in discharge chamber of ion thruster, the energy balance in discharge chamber was studied. Based on 0-D model of discharge performance, the relation of currents balance in discharge chamber was analyzed, combined with the potential distribution, the model of energy loss in discharge chamber was established. Using the LIPS200 thruster as the object of calculation, the respective distribution ratio of various energy loss in the discharge chamber was obtained, and the results between the model calculated and literature were contrasted; Further validation was carried out by test in more conditions (corresponding anode current is 4.0-4.4 A, anode voltage is 34-38 V), and the results indicate that the maximum error is no more than 3%.
