Computational simulation of a plasma thruster for miniaturized satellites
Electric propulsion, Plasma, Ions, CubeSats
Electric thrusters, also known as plasma thrusters, represent a type of space propulsion devices that employ electromagnetic forces to generate thrust. Plasma thrusters have a number of advantages compared to chemical propulsion, for example, high specific impulse and high efficiency, and are commonly employed for station-keeping of satellites, orbit transfer maneuvers and deep-space missions.
The popularization of mini and microsatellites in low-cost space missions have resulted in a growing interest in the development of low-power thrusters. The ambipolar thruster is a type of plasma thruster which is simple to construct and can be scaled to smaller dimensions and lower operational powers. In this monograph a reduced version of the ambipolar thruster is proposed for miniaturized satellites, commercially known as “PocketQube”. Numerical simulations are performed to obtain the specific impulse, which is an important parameter for the evaluation of thrusters. Potential applications of this technology are discussed, for example, extending space missions, and de-orbiting. The results presented here can represent a contribution to the development of space technologies.
