Abstract
This study is a basic research on the ionic wind propulsion technique, and the thrust characteristics of the ionic wind propulsion device of a two-stage series structure with an acceleration electrode applied with a negative voltage are studied based on various theoretical equations suggested in previous studies. Experimental results show that the current measured at the acceleration electrode increased as the amount of corona current decreased as the negative voltage applied to the accelerating electrode increased. The ionic wind velocity increased as the negative voltage applied to the acceleration electrode increased, and the thrust increased by up to 72.9%. In the condition of the applied voltage with the maximum thrust, the thrust efficiency decreased rapidly, but the kinetic energy efficiency decreased less.
