Abstract

This PhD project focuses on the experimental study and modeling of electrospray propulsion systems based on ionic liquids. Through a series of characterization campaigns on both single emitters and emitter arrays, the project will investigate key aspects such as I-V behavior, emission modes, operational stability, and beam angular distribution. The goal is to develop a deeper understanding of emission dynamics across different configurations and extract insights useful for the design and optimization of scalable thruster architectures. As a complementary tool, machine learning techniques will be employed to build predictive models trained on experimental data, enabling interpretation and generalization of system behavior. The project aims to produce applicable knowledge for the development of next-generation high-precision space propulsion platforms.
