Abstract
The times to thermal explosion of a mixed energetic material of the NEPE (Nitrate Ester Plasticized PolyEster) type were experimentally determined on samples in the form of cylinders with a diameter and a height of 4 mm, pressed into hermetic steel shells with a filling density close to theoretical. The experiments were carried out under isoperibolic conditions in the temperature range from 110 to 140 C. The obtained experimental values of are compared with those calculated by the system of equations of thermal conductivity and kinetics using the kinetic characteristics obtained by the DSC (differential scanning calorimetry) method. It is shown that the results of experiments and numerical calculations are in the best agreement when using the formal kinetic equation of a branched chain reaction.
