Abstract:
Intensity and profile of applied magnetic field are working parameters of great significance for the applied field magnetoplasmadynamic thruster(AF-MPDT).A 100 kW AF-MPDT principle prototype developed by Beijing Institute of Control Engineering and Beihang University was used to estimate the performance of MPDT under medium power with applied magnetic field varied from 30 mT to 230 mT.A target thrust measurement method under high temperature and vibrating environment was applied.The test results show that within a certain range,increasing the intensity of applied magnetic field could improve the thrust,impulse,discharge voltage and efficiency of AF-MPDT under low power.Besides, the performance improvement of AF-MPDT is more obviouse under higher discharge current.Further analysis shows that when the AF-MPDT was operated under low power, thrust and impulse are proportional to the square root for intensity of magnetic field; discharge voltage is proportional to intensity of magnetic field; efficiency increases with intensity of magnetic field but finally reaches the up limit under the corresponding working condition.
