Fluoro-Hydrogenated Ionic Liquids (FHIL) for High-Performance Electrospray Propulsion

Abstract

The goal of the proposed effort is to investigate the emission properties of Fluoro-Hydrogenated Ionic Liquids (FHIL) and their potential implementation in electrospray propulsion. FHILs properties set them apart from practically all other ionic liquids available in the market or described in the literature. In particular, their very high electrical conductivity and very low viscosity could enable an increase of emitted current and thrust of at least an order of magnitude over conventional liquids. Such an increase would allow electrospray thrusters based on arrays of individual emitters to perform at similar thrust density levels (per unit area) as low power Hall thrusters but with vastly superior thrust per unit mass and volume.
