Investigation of influences parameters and topology of magnetic field peripheral zone stationary plasma thruster on the efficiency of the cathode-compensator
In this paper it is investigated an influence of magnetic field characteristics (parameters and topology) of SPT using SPT-100 thruster model on efficiency of cathode-compensator operation while the cathode is translated. During investigations the comparison results of experiments and calculations suggests influence on efficiency of cathode-compensator operation either magnetic field topology or magnetic field induction in cathode position. It is ...
Modeling of the cathode thermal conditions
This article provides results of the cathode of stationary plasma engine thermal vacuum test with various operating modes simulated, a thermal calculation and the cathode thermal mathematical model verification. Based on the calculations, the cathode thermal model and operating performances ...
Creation of the effective cathode jack for the micro-SPD
This paper presents the scope of challenges which are faced in development and manufacturing of the cathode-compensator dedicated for micro-SPTs, and possible ways of how to overcome them. As compared to standard models, such a cathode shall be smaller in dimensions, shall have a lover propellant flow rate, as well as lover heater power and power consumption when self-operated; and it shall be able to operate in the current range of 0.3…1A or lower.
