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.
