三相交流螺旋通道磁流体推进器

Three phase alternating spiral channel magnetohydrodynamic propeller

本文提出一种新型交流磁流体推进器结构—三相交流螺旋通道磁流体推进器。在给定磁场边界条件的情况下,分析了螺旋通道区域的磁场的分布。在此基础上,推导了推进器的电磁力、电磁功率、电磁效率与各参量的关系式。最后论述了这种结构的推进器与已经提出的交流磁流体推进器相比所具有的优点。

This paper puts forward a new kind of alternating magnetohydrodynamic propeller structure, which is a three phase alternating spiral channel magnetohydro-dynamic propeller. Under the situation that the magnetic field boundary condition is given, the magnetic field distribution of spiral channel is analyzed. On this foundation, the relation is deduced among the electromagnetic force, electromagnetic power, electromagnetic efficiency of the propeller and all kinds of parameters. Finally, the advantages of this propeller are discussed with alternating magnetohydrodynamic propeller that has already been put forward.
