This paper provides an overview of the GRC high power pulsed thruster test facility, and presents preliminary performance data for a quasi-steady baseline MPD thruster geometry. Nomenclature b = thrust coefficient.

A quasi-steady MPD thruster doesn’t fit for practical use in space, because of its weight and complicated system. And, conventional MPD thrusters were equipped with water-cooled coils which apply the magnetic field.

So, the thruster systems is complicated, because of increasing external systems, such as circulating pump and heater. designs for both quasi-steady (King and RudolphRudolph and egg ) and steady-state (Coomes et al.

For the experiments in this paper, the thruster was fed. In this research, in order to confirm the quasi-steady state in the operation of MPD thruster, the propulsion performance per discharging time was acquired using the power supply developed in the previous research.

As a result, time independence was observed after the discharge time of 1 ms and operation with high quasi-steady was confirmed. walls of the rocket core. High-temperature ceramic plasma-facing surfaces handle the thermal radiation: the principal heat transfer mechanism from the discharge.

The rocket uses a helicon plasma source [5,6] for efficient plasma production in the first stage. This plasma is energized further by an ion cyclotron heating (ICH) RF.

We live in a complex, interactive, and increasingly borderless world in which our lives are impacted more than ever before by events occurring outside the sphere of our personal influence. A recycling application could consist in converting the waste power into electric power for a downstream electric propulsion thruster, or to boost the performance of the main electric propulsion thruster.
