抄録

Use of liquid propellants, such as water or ethanol, as an alternative to the most common propellant, solid Teflon, for a pulsed plasma thruster (PPT) is reported to improve the performance of PPT by excluding the drawbacks of uncontrollable propellant feed rate and timing, while maintaining the advantages of digital control features. In this study, we propose to use dimethyl ether (DME) as for the liquid propellant PPT, because DME has a low freezing point (131K at standard pressure) and an expedient vapor pressure (6 atm at standard temperature), both of which eliminate the need for a heater and pressurant when using a water or ethanol propellant. A series of experiments using a prototype DME-PPT with parallel-plate electrodes demonstrated reliable operation with a tendency for the electromagnetic impulse bit I_bit to increase in proportion to the stored capacitor energy E_c up to I_bit = 53μNs at E_c = 13J.
