Abstract

Abstract: For the purpose of exploring the application of magnetohydrodynamic(MHD) on hypersonic vehicle，high temperature gas experiment is conducted based on the gas generator. Some details include the choice of gas medium and operating mode，the debugging mechanism，the operation of the experiment system are introduced. The results show that in the condition of mixing ratio being 1.2～12，gas temperature meets the requirements of more than 2600K when using the kerosene as fuel，oxygen as oxidizer. Set the kerosene flow rate as a benchmark，regulating the pressure of oxygen before the orifice meter in the oxygen pipeline can be very good to adjust the gas temperature. The timing of the system operation is determined after debugging，and run the experiment under the condition that the combustion temperature is 3278.5K. Conductivity test results show that the conductivity average reached 10S/m and peak reached 15S/m when the gas temperature reached 2750K，and the conductivity of high temperature gas has the ability to meet the requirements of the MHD power generation technology.

摘要： 为探索磁流体发电技术在高超声速飞行器上的应用，研制了基于燃气发生器的高温燃气实验系统。介绍了燃烧工质的选取、工况的选择以及实验系统的调试机理、运行情况。结果表明，采用航空煤油做燃料，气氧做氧化剂，混合比为1.2～12的条件下满足温度大于2600K的要求；煤油流量作为基准值，通过调节氧气路孔板流量计前压力能很好地调节燃气发生器的温度；通过调试确定了系统运行的时序，并进行了燃烧温度为3278.5K的点火实验。电导率的测试实验表明，在燃气温度2750K的情况下，燃气电导率的平均值达到10S/m，峰值15S/m，满足磁流体发电的技术要求。
