Propellant supply device of magnetic plasma power propulsion system

Abstract

A propellant supply device of a magnetic plasma power propulsion system comprises a propellant low-temperature storage module, a pressure adjusting module and a flow adjusting module. The propellant low-temperature storage module is used for cooling, compressing and storing a propellant; the propellant output by the propellant low-temperature storage module is provided for a cathode and an anode of the propulsion system through the pressure adjusting module and the flow adjusting module in sequence; the pressure adjusting module is used for reducing the pressure of the propellant; and the flow adjusting module is used for adjusting the flow output to the cathode and the anode of the propulsion system. An active refrigeration zero-evaporation scheme is adopted, so that the volume and the weight of a propellant storage box are greatly reduced; the large-range propellant flow adjusting module is adopted, and precise control over the propellant flow can be completed at the same time; the propellant low-temperature storage module, the pressure adjusting module and the flow adjusting module are integrated, so that the volume and the weight of the propellant supply system are greatly reduced; and argon is adopted as the propellant, so that the consumption cost of the propellant is saved.

Problems solved by technology

However, gases with relatively light molecular weight are usually stored at high pressure and normal temperature, and their storage density is low, which leads to a significant increase in the volume of the propellant tank required for on-orbit operation, which greatly limits the high-power magnetoplasma propulsion system. in-orbit application
