| Abstract: | A uniform model of RF ion thruster discharge chamber was established to research the discharge principles and regulations among RF ion thruster working parameters, geometry parameters and its discharge performances. The solution of model and conclusions of test is compared in the paper. It is found that by reducing the aspect ratio or increasing the mass flow rate, the grid voltage and the RF power can increase the thrust beam current and improve the thruster performance. Test and simulation results show that the discharge chamber uniform model can be used to study the performance of RF ion thrusters. |
