Riassunto analitico
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.
