Effect of Electrode Angle on Pulsed Plasma Thruster Performance

Abstract

This study focused on the development of a pulsed plasma thruster (PPT) using various electrode angles, including asymmetric ones. Four electrode angles and asymmetric configuration setups were selected and examined, and we revealed their influence on the performance and reliability of the PPT. The original design, manufacture, and demonstration of the PPT were completed. An interesting phenomenon was observed and elucidated using a high-speed camera, and hypothetical solutions were addressed. In addition, a Taguchi method was employed to analyze the effects of design parameters on PPT performance and reliability. The results demonstrated that the electrodes with a deflection angle of 40° would deteriorate the reliability of PPT discharging, and the corresponding failure rate would reach 50% and more.
