Many research programs are focusing the attention on green propellants. Many advantages are associated with their use, in particular the cost reduction. This thesis discusses the implementation of the ADN-based propellant, LMP-103S, on the Arcjet system. Although hydrazine is well used as propellant, it is high in toxicity and difficult for handling. A simple numerical model, developed for this thesis, predicts lower LMP-103S performance than hydrazine in low-power Arcjet systems. The main operative problems of Arcjet thruster relates to erosion, the possible solutions are discussed and the design of a preliminary engineering model is done. The revision on the Arcjet technology and systems reveals that the gas generator and the thruster unit are not mature for the implementation of LMP-103S in the Arcjet system.
