摘　　要：本文首先提出了一种具有双螺旋通道的新型三相交流磁流体推进器,介绍了其圆筒形磁体外部磁场的屏蔽方式:强磁屏蔽和抗磁屏蔽。分析了在不同的屏蔽方式下磁体外部磁场的分布。最后导出在外螺旋通道产生的电磁力与各参量的关系。A new kind of three phase alternating magnetohydrodynamic propeller structure with double spiral channel is put forward in the paper, and magnetic shielding and anti-magnetic shielding are introduced in the external spiral channel. Under the different shielding ways, the magnetic field distribution of external spiral channel is analyzed. Finally, the relation is deduced between the electromagnetism force and all kinds of parameters.
