摘　　要：本文从能量转换入手，建立了磁流体推进器功率流程图；在效率分析的基础上，提出了磁流体推进器的标么速度和效率方程，清晰地揭示了推进速度、效率与负荷因子和管道损耗之间的关系，在无需具体了解推进器结构、电磁和水力参数的情况下，为分析研究管道损耗对推进速度和效率的影响提供了一条新途径。In this paper,based on the energy conversion,a power flow diagram for MHD is illustrated,and by analyzing the efficiency,a set of the per unit velocity and efficiency equations for MHD thrusters is Presented. These clearly show the relationship between the load factor, the duct loss and the velocity or the efficiency, and provide a new method for studying the effect of the duct loss on the velocity or the efficiency without knowing the structure,electromagnetic and fluid parameters of the thruster.
