| Abstract | A Pulsed Plasma Thruster (PPT) is an electric space propulsion device mostly used for spacecraft orbit maintenance and attitude control. One of the most common issues with PPTs is the Late Time Ablation (LTA) - the sublimation of propellant that occurs after the main electric discharge, reducing propellant use efficiency. The Double Discharge PPT (DD-PPT) has two stages: The first stage works as a regular PPT and the second stage employs additional electric discharges to accelerate the first dis-charge plasma and the LTA. This work studied a DD-PPT and analyzed its efficiency and performance while varying the levels of energy employed on each of the two stages in order to archive maximum performance. A new electric circuit was designed to enable energy levels distribution amongst the two stages of the DD-PPT. An oscilloscope and a Rogowski current probe were used to estimate the impulse bit and a precision scale was used for measuring propellant mass variation. Inductance gradients were calculated using a mathematical model. Thruster tests were performed in a vacuum chamber with pres-sure of ~10-6 mbar. The results showed a significant increase in specific impulse. The optimum config-uration of energy distribution occurred when a smaller percentage of the total energy was employed in the primary stage (for ablation) and a greater percentage of the total energy was employed in the second stage, used for plasma acceleration. | |||
