国内外多模式离子推力器的性能对比

Performance comparison of multi-mode ion thrusters at home and abroad

多模式性能是离子推力器产品应用及产品研制过程中需考虑的重要性能之一。通过对国内外成熟度较高的离子推力器产品的多模式性能对比分析,获得了不同类型离子推力器的多模式性能变化规律,证明了国内离子推力器的多模式性能已达到与国外先进多模式离子推力器相当的水平。定义和对比分析了多模式离子推力器的性能调节能力,结果表明直流环切场推力器性能调节能力最好,射频放电推力器次之,直流发散场推力器最低。

Multi-mode performance is one of the crucial aspects in the development and application of ion thruster.By comparing and analyzing the multi-mode performance of ion thrusters at home and abroad,the variation law of multi-mode performance of different types of ion thrusters is obtained,which proves that the multi-mode performance of domestic ion thrusters has come up to the advanced world level.At the same time,the performance adjustment capability of multi-mode ion thruster is defined and compared.In addition,the DC toroidal field thruster has the best performance adjustment ability,followed by the RF discharge thruster,and the DC divergent field thruster has the lowest performance adjustment ability.
