摘要: In this paper, a new numerical modeling method that combines modified electromechanical model with Teflon ablation is proposed to simulate the working process of micro-pulsed plasma thruster (μPPT). The mass accumulation during discharge and non-Fourier effect are considered improve simulation accuracy. Simulation results in good agreement experimental results. Furthermore, influence both electrical structural parts on performance μPPT was investigated by applying combined model. It proven large capacitance capacitor gap-to-plate-width ratios can effectively comprehensive concluding specific impulse, impulse bit, efficiency. not only validate theoretical model, but also guide design operation optimization μPPT.
