ADN-BASED PROPULSION FOR SPACECRAFT -KEY REQUIREMENTS AND EXPERIMENTAL VERIFICATION

This paper describes the ongoing work to develop a storable liquid monopropellant for spacecraft propulsion based on Ammoniumdinitramide, ADN, and related rocket engine technologies. The primary objective of this effort is to reduce operational hazards and improve performance as compared with monopropellant hydrazine. Previous papers 1,2,3,4 have described the basic properties of ADN, possible propellant compositions and experimental results from test firings of small rocket engines.
