Specific Impulse and Absolute Chemical Hardness

preprint
submitted on 04.09.2020 and posted on 11.09.2020 by George Santos Marinho, Robson de Farias

The present work is dedicated to show that there are relationships between the absolute chemical hardness (η) of monopropellants and their specific impulse (Is). A total of sixteen monopropellants have been modelled and the absolute hardness obtained by quantum chemical calculations. The following equation was obtained: Is = 17.562 η + 125.551, providing specific impulse results in very good agreement with reference values.
