Recent Developments for Prediction of Power of Aromatic and Non‐Aromatic Energetic Materials along with a Novel Computer Code for Prediction of Their Power

Abstract

The explosive power or strength of an energetic material shows its capacity for doing useful work. This work reviews recent developments for prediction of power of energetic compounds. A new user‐friendly computer code is also introduced to predict the relative power of a desired energetic compound as compared to 2,4,6‐trinitrotoluene (TNT). It is based on the best available methods, which can be used for different types of energetic compounds including nitroaromatics, nitroaliphatics, nitramines, and nitrate esters. The computed relative powers are consistent with the measured data for some new materials containing complex molecular structures.

Because heats of detonation and combustion are very important parameters for detonation and combustion performances [22,[31][32][33][34][35][36][37][38][39][40], respectively, PMDN with high value of heat of decomposition (742 J/g) can be considered as an attractive high energetic binder. Two results can be obtained from three reactions given in Scheme 2 and thermal analysis data: (a) it can be expected that PMP has the higher positive value of D f H q solid than PMN and PMDN; and (b) PMDN may be more efficient binder in providing higher detonation and combustion performances than PMN and PMP due to higher value of its heat of decomposition [22,47,48].…”

“…Introducing energetic functional groups like azide and nitro groups in a desired polymer can increase its potential heat content [25][26][27][28][29][30]. The use of these polymers as energetic binders in explosive or propellant compositions can increase their detonation and propulsion performance [22,[31][32][33][34][35][36][37][38][39][40]. The purpose of this work is to graft energetic groups in PECH for improvement of its energetic content.…”
