摘要

The present paper describes the effort to develop a novel storable liquid monopropellant for space applications based on Ammoniumdinitramide, ADN. A previous paper has described the propellant formulation, basic properties of ADN and possible propellant compositions based on ADN. With low toxicity, handling safety and high performance as driving criterions, a baseline propellant consisting of 61% ADN, 26% water and 13% glycerol was formulated and tested. Other ADN-based propellant blends have also been formulated and tested.rnThis paper contains a discussion on propellant candidates and testing of different propellant blends with emphasis on combustion stability and pulse performance. The outcome of the tests performed is that combustion stability can be significantly improved by both modifying the rocket engine design and the propellant composition. Pulses between 0.3 seconds and approximately 1 minute have been run, and consecutive restarts have been demonstrated under ambient and vacuum conditions.rnThe present paper does also discuss some of the most critical issues in the development of a rocket engine and a propulsion system for ADN-based propellants. The major issues in this context are long-lived catalyst bed or an alternative ignition method and high temperature resistant materials. The combustion temperature of ADN-based propellants is in the 2000 K range.
