Numerical suite for the design, simulation and optimization of cathode-less plasma thrusters

Abstract

Abstract. A numerical suite developed for the analysis and design of cathodeless plasma thrusters is presented. The suite includes a Global Model that estimates the thruster's propulsive performance by means of a balance of electron energy and population density, and a 3D numerical strategy to assess plasma behavior. The suite incorporates a FLUID and EM modules to solve plasma transport and electromagnetic wave propagation within the discharge chamber. The PLUME module, managed by the Starfish code, handles plasma dynamics in the magnetic nozzle using the electrostatic particle-in-cell approach. The suite has been validated against thrust measurements from a Helicon Plasma Thruster demonstrating the suite's potential for optimizing the design and operation of cathodeless plasma thrusters for space propulsion applications.
