Abstract

Electric propulsion is a current mainstay within the aerospace engineering field used for satellites and deep-space spacecraft. For a newly developed propellant, it is extremely important to understand and quantify the plasma plume behavior exhibited during thruster firing. This work researches and develops significant plasma diagnostics to characterize the plume of an innovative electrically ignited solid propellant. Diagnostics developed include a Triple Langmuir Probe, Faraday Cup, and Single Langmuir Probe Rake. These tools allow the quantification of chief plasma parameters such as electron number density and the electron-fluid temperature. Results from the application of these diagnostics will be presented to show successful plasma characterization.

Biography
