ARCJET Fundamentals: Experiments and Non-Equilibrium Flow Modeling.

reportActive / Technical Report | Accession Number: ADA308578 | Open PDF

Abstract:

Experimental investigations and theoretical modeling of the energy deposition and acceleration processes in 1kW-class arcjet thrusters using hydrazine propellant are presented. The report highlights detailed research in arcjet fundamentals that was reported in the two Ph.D. theses of S.A. Bufton and T.W. Megli. We report for the first time the evidence of thermal non-equilibrium different electron and gas temperatures. Chemical kinetics for hydrazine dissociation and ionization play important roles in the overall energy conversion. Electrostatic probe measurements at the exit plane validate the model.
