The use of aromatic hydrocarbons as plasma thruster propellants represents a promising alternative to xenon, providing storage advantages, low ionization losses, high specific thrust, as well as low post-ionization fragmentation. However, using aromatic hydrocarbons requires significant changes at propulsion system level, in terms of storage and feeding system, and for the experimental setup, since conventional vacuum facilities for electric propulsion are designed to operate with inert gaseous propellants. The focus of the proposed project is on the design, prototyping, and evaluation of the propellant feed system based on the aromatic hydrocarbon naphthalene. After reviewing existing feed system technologies, a design was implemented considering the physical and chemical properties of the candidate propellant and the flow theory along the system.
