通过几种理论模型讨论了螺旋推进器的内外等离子体动力学。螺旋源内部的主要等离子体过程有：波能吸收、气体电离、磁连接、霍尔电流形成和亚音速等离子体流。外扩式磁喷管中发生的过程有：轴向超声速加速、径向稀疏、霍尔电流演化、推力增量和下游脱离。还讨论了无电流双电层（CFDL）的可能形成。重点
Internalandexternalplasmadynamicsinaheliconthrusterarediscussed through several theoretical models. Main plasma processes inside the helicon source are: wave energy absorption, gas ionization, magnetic con¦nement, Hall current formation, and subsonic plasma §ow. The processes taking place in the external divergent magnetic nozzle are: axial supersonic acceleration, radial rarefaction, Hall current evolution, thrust increment, and downstream detachment. The possible formation of a current-free double layer (CFDL) is discussed too. Emphasis is
