Abstract
Pulsed Plasma Thruster (PPT) is one of the promising space propulsion devices for the micro- and nano-satellites as the following advantages: simplicity, lightweight, robustness, and low power consumption. Moreover, PPT can generate very small impulse bits with high specific impulse. Therefore PPT has great advantages as a precision attitude control. Although μPPTs and their relevant issues have been investigated to a certain degree in recent years, but as a result of the fact that PPT performance is a function of a lot of different parameters like geometrical dimensions, discharge energy, capacitor characteristics, etc and also because of its sophisticated physics; it is felt that issues related to developing an optimized μPPT needs to be investigated in greater detail for a PPT with smaller dimensions and better performance. Therefore, following the development of a laboratory benchmark rectangular breech-fed PPT, a wide range parametric study has been conducted on investigating the effect of discharge energy on PPT performance. The PPT impulse bit varied from about 0.4 mN-s to more than 1.3 mN-s while discharge energy changed from less than 10 J to more than 50 J. Specific impulse also increased from 200 s to 110 s. This paper reviews the results of the mentioned parametric study in brief.
