Ammonium dinitramide (ADN) is a new direction of future chemical propulsion technology.For ADN decomposition and combustion chemical reaction mechanism, there is no mature theoretical research results.At the same time, the latest progress of relevant research is summarized and summarized, and ADN A new method to predict the internal reaction parameters of ADN-based engine based on Gibbs free energy minimization principle is developed. The adiabatic flame temperature and combustion of two possible paths of ADN decomposition combustion are theoretically calculated Product components, proving the rationality of the proposed reaction path of ADN decomposition combustion.The contents and results of the study contribute to deepen the understanding of the physical properties of ADN pyrolysis and combustion reactions, and have important theories for the engineering practice of ADN-based engines in China Guiding significance.
