Investigation of Ionic Liquid Electrospray Extraction Mechanisms

Anirudh Thuppul Gary Li Richard Wirz

In collaboration with AFRL, we investigate extraction mechanisms in ionic liquid electrospray thrusters for optimizing for the design of multi-emitter arrays. Initial studies will include electrostatic simulation of the emitter-extractor domain to determine particle paths for varying geometries. As this project is ongoing, future efforts may include collaborative experimental investigation of thruster prototypes, electrospray plume characterization, and electrohydrodynamic modeling and simulation.
