摘　　要：阐述了磁流体推进系统的不同分类和面临的问题,着重研究了直流内磁式磁流体推进系统的结构设计和优化.为进一步提高推进效率,从动量和能量守恒出发提出一种全局计算方法,研究船舶磁流体推进器的几何形状、尺寸和位置等参数,并通过对其不同组件和产生损失的综合分析得出一种优化模型.The different classification and the facing problems of the system are described, and the structure design and optimization are studied especially. In order to improve the propulsion efficiency,according to momentum and energy conservation,this work present a global calculation approach to get the geometry, dimensions, shape and position of the MHD propeller on the ship. By taking into account the different components of the propeller and their losses generated we deduce an optimization model.
