Ionization and Acceleration of N2/O2 Mixtures for Air-Breathing Electric Propulsion
Abstract
The objective of the proposed research is to create a model-based approach to the ionization of molecular propellants with varying composition as well as predictive lifetime modeling capability for insulating materials in the presence of ionized air, by investigating plasma properties, ionic species, and propellant utilization of a broad range of air composition mixtures and densities that mimic those expect in very low orbit conditions, and develop an erosion model that address the limitation of our current model by developing physics-based simulations of the thermomechanical failure of quartz and other insulating materials due to impact of ionized molecules.
