Simulation Researches on the Pulsed Plasma Thruster with Tongue-Shaped and Flared Electrodes

Abstract

Pulsed plasma thruster (PPT) is a promising electric propulsion device with the advantage of high specific impulse and light quality. This paper studied a mathematical model of the pulsed plasma thruster with tongue-shaped and flared electrodes. The results of simulation are closer to the experiment. It also simulated the performance of the pulsed plasma thruster with different structures of electrodes. It is possible to conclude that different electrodes affect the performance of the pulsed plasma thruster.
