Abstract: This work presents a new simple method for predicting electric spark sensitivity of nitramine energetic compounds. This method is based on the calculated detonation velocity at maximum nominal density (theoretical maximum density) and then corrected for some nitramines which have some specific molecular structure. The predicted electric spark sensitivity by new method are compared with calculated results on the basis of quantum mechanical computations for 17 nitramines so that the root mean square (rms) deviations from experiment for new and complicated quantum mechanical methods are 1.23 and 4.02 J, respectively. The new model is also used for two new nitamine explosives TNAZ [1,3,3-trinitroazatidine] and TEX [4,10-dinitro-2,6,8,10-tetraoxa-4,10-diazaisowurtzitane] in which predicted results are close to measured values.
