Abstract

Ion thruster is the most efficient population system of satellite to control its orbits in deep space. Total efficiency, thrust, and specific impulse are the key characterization parameters of an ion thruster which define its performance. At present, total efficiency is limited within the range of 36–68%. In this paper, a new grid design is discussed to increase the total efficiency and thrust of ion thruster wherein screen grid has chamfered edges. The ion beam dynamics were simulated in OPERA14.0-3D. The simulated result is shown to have increased thrust and total efficiency from 0.196–0.364 mN and 41.29–74.66%, respectively.
