A thermodynamic analysis of the energetic parameters and the combustion products of model energetic systems based on the mixture tetranitromethane + tetra(difluoramino)methane as oxidizer, and combustible components (either polyethylene, or carbon, or boron, or decaborane) has been accomplished. The optimal ratios between the components for achieving the maximal specific impulse have been found. The nature of the combustion products, the dependence of their distribution on the percentage of the components, and how the distribution of the combustion products influences the specific impulse value, have been studied.
