Secondary Species formed from ionic liquid electrospray ion plume impacts with propellant thin films
Giuliana Caramella Hofheins, Aleksandra B. Biedron, Elaine M Petro
The operational lifetime of ionic liquid electrospray propulsion systems is limited by plume-extractor electrode interactions. Over time, propellant accumulation, surface erosion,…
Ab initio Simulations of EMI-BF4 Neutral-Surface Interactions in Electrospray Thrusters
Nicholas Laws, Elaine Petro
Electrospray thrusters promise compact, high specific impulse propulsion for small spacecraft, yet ground characterization remains confounded by secondary species emission and inco…
Electrospray Propulsion Time-of-Flight Secondary Ion Mass Spectrometry Diagnostic
Giuliana Caramella Hofheins, Zach Ulibarri, Elaine M. Petro
The design and capability of a novel time-of-flight secondary ion mass spectrometry electrospray propulsion diagnostic is presented to investigate secondary species emission from s…
Propellant Discovery For Electrospray Thrusters Using Machine Learning
Rafid Bendimerad, Elaine Petro
This study introduces a machine learning framework to predict the suitability of ionic liquids with unknown physical properties as propellants for electrospray thrusters based on t…
