摘　　要：阐述了磁控进气道的基本原理,建立了一维数学模型。对磁控进气道设计影响因素磁感应强度、负载系数和通道截面积变化率进行了特性分析,得到磁控进气道出口参数随设计参数的变化规律,为磁控进气道设计提供了依据。给出了一组磁控进气道设计参数,仿真结果表明采用磁控进气道技术可以有效地调节燃烧室进口来流状态,提高比冲,拓宽飞行马赫数范围。The basic principle and one-dimensional mathematic model of MagnetoHydrodynamic (MHD) controlled inlet were presented. Based on the influence factors analysis of MHD controlled inlet design, including magnetic field intensity, load factor and variation rate of cross section, the effect of design parameters on the exit aerodynamic parameters was given, which provided the basis of MHD controlled inlet design. A set of design parameters was given. The simulation results show that the application of MHD control technology to inlet design can effectively regulate combustor incoming flow state, improve specific impulse and extend the operating range of flight Mach number.
