Common methods for performance prediction of novel energetic materials, based on calculated heats of formation (using e.g. CBS-4M), reach their limits when calculating Energetic Coordination Compounds (ECC) with transition metal centers. Another approach for estimating detonation parameters uses increment values of structural fragments and chemical bonds, mainly used in Russia. The algorithm of this calculator for predicting the detonation velocity of ECC is based on this method and Ilyushin’s modifications for the calculation of energetic transition metal complexes.
