| Abstract: | The low power arc jet thrusters with different structures and sizes were designed. The operation parameters and performances of arcjet were tested by the ground experiment. The effects of propellant entry, constrictor size and electrode material on performance were analyzed in detail and the optimum constrictor size was obtained. The resuhs show that the structure and size can significantly affect the working performances of thruster. |
