Features of ignition and thermal decomposition of hems ammonium nitrate and active binder based
Results of experimental study of ignition process of high-energy materials (HEMs) based on ammonium nitrate and active combustible-binder containing aluminum ultrafine powder (UFP) CO2-laser radiation are presented. It was established that the effectiveness of additives of aluminum UFP in the HEMs increases with decreasing laser intensity, the temperature of combustion surface upon ignition by radiant heat flux of HEMs containing aluminum UFP is ~580-610 °C and ~530-820 °C - for the HEMs compositions with aluminum micron powder ASD-4 for the value of radiation intensity 70 W/cm2. It is shown that with increasing storage time HEMs activity of aluminum UFP in the studied compositions is reduced.
