Abstract

Numerical modeling of the pulsed inductive thruster exercising a time-dependent, two-dimensional, axisymmetric magnetohydrodynamics code provides bilateral validation of the thruster's measured performance and the code's capability of capturing the pertinent physical processes. Computed impulse values for helium and argon propellants demonstrate excellent correlation to the experimental data for a range of energy levels and propellant-mass values. Quantitative energy deposition analysis confirms the thruster's approximately constant-efficiency operation and captures the experimentally observed, critical-mass phenomenon. An idealized model produced a simple impulse expression for this energy range that expands the validity of the aforementioned insights to other propellants and corroborates the thruster's singular operation with ammonia propellant The simple impulse expression produced compares well with experimental trends and can be used to guide design and optimization of operating conditions.
