Characterization of ionic liquid multimode propellant operating in a porous glass electrospray thruster
Multimode space propulsion is an emerging technology that shows a promising increase in mission flexibility, adaptability, and mass savings for specific missions [1]. Finding a propellant that operates well in multiple propulsive modes is a key step in getting multimode propulsion systems flying in space. This study characterizes a novel multimode propellant named FAM-110A through operation in a porous glass electrospray thruster. Measurements acquired include current-voltage characteristic curves, plume energy via a retarding potential analyzer, and mass to charge ratio via a linear time of flight spectrometer. It is demonstrated that FAM-110A operates stably in cation emission, anion emission, and bipolar operational modes.
The propellant has a higher onset voltage and emits less current than EMIM BFoperating in the same thruster. The electrospray plume emitted during operation with FAM-110A appears to be monoenergetic and the time of flight data indicates that the EMIM monomer species is most likely the dominant species being emitted during cation emission operation.

Abstract

Multimode space propulsion is an emerging technology that shows a promising increase in mission flexibility, adaptability, and mass savings for specific missions [1]. Finding a propellant that operates well in multiple propulsive modes is a key step in getting multimode propulsion systems flying in space. This study characterizes a novel multimode propellant named FAM-110A through operation in a porous glass electrospray thruster. Measurements acquired include current-voltage characteristic curves, plume energy via a retarding potential analyzer, and mass to charge ratio via a linear time of flight spectrometer. It is demonstrated that FAM-110A operates stably in cation emission, anion emission, and bipolar operational modes.
The propellant has a higher onset voltage and emits less current than EMIM BFoperating in the same thruster. The electrospray plume emitted during operation with FAM-110A appears to be monoenergetic and the time of flight data indicates that the EMIM monomer species is most likely the dominant species being emitted during cation emission operation.
