摘　　要：为了开展高温磁流体功率提取、磁流体加速、磁流体流动控制等磁流体动力技术实验,研制了基于高温燃气发生器的磁流体动力技术实验系统。介绍了高温磁流体动力技术实验系统的基本组成,设计思想及运行情况。燃气发生器采用航空煤油和气氧燃烧,产生最高温度可达3256K的高温燃气,通过添加辅助电离种子K2CO3,可以得到电导率为11.6S/m的导电流体;高温燃气经喷管的加速,在出口得到马赫数1.5的超声速导电流体;实验系统调试实现了15s以上稳定运行,表明具备了开展较长时间高温磁流体动力实验的能力。In order to carry out high temperature magnetohydrodynamic （MHD） technology such as MHD power generation, MHD acceleration and MHD flow control, a MHD technology experimental system based on high temperature combustion chamber was developed. The basic element, design idea and operation of the high temperature MHD technology experimental system were introduced. With aviation kerosene and oxygen, the com- bustion chamber can reach a maximum temperature of 3256K. Then a conductive fluid in which the conductivity is 11.6S/m is acquired by adding auxiliary ionization K2CO3. Finally, through acceleration in the nozzle, the con- ductive fluid is transformed into a supersonic conductive fluid with Mach number 1.5. Pilot run of the system achieved stable operation for more than 15s, showing that the system is capable of conducting high temperature MHD experiments with a longer time frame.
