TLDR
In this article, a comparison of multi-mode spacecraft propulsion systems utilizing a chemical monopropellant or bipropellants thruster and high-power electric Hall, arcjet, or pulsed inductive thruster were analyzed and compared in terms of mission capabilities.Abstract:
Multi-mode spacecraft propulsion systems utilizing a chemical monopropellant or bipropellant thruster and high-power electric Hall, arcjet, or pulsed inductive thruster were analyzed and compared in terms of mission capabilities. These systems are most effective compared to an all-chemical system when greater than 25% of the total delta-V is accomplished by the electric system due to the high mass requirements of the power system. Additionally, monopropellant systems are more effective in terms of both reduced system mass as well as decreased burn duration over bipropellant systems despite having 33% lower specific impulse and 1/10 th the thrust. The monopropellant/PIT system yielded the lowest total system mass, however the monopropellant/arcjet had the highest transportation rates over all potential chemical/electric delta-V ratios.read more
