Abstract

The possibilities of increasing the acceleration ability (AA) of energetic materials due to creation of compositions combining high explosives (HE) with positive and negative oxygen balance are analyzed. For calculations, three relatively new compounds were selected as HE-oxidizers: 3,6-dinitro-1,4-bis(trinitromethyl)-1,4-dihydropyrazolo[4,3-c]pyrazole; 4,4′5,5′-tetranitro-2,2′-bis(trinitromethyl)-2Н,2′Н-3,3′-bipyrazole; 2-dinitromethyl-5-nitrotetrazole. HMX and CL-20 performed the function of HE-fuel. From the calculations it follows that the AA of HMX increases markedly with the addition of mentioned oxidizers, and the introduction of oxidizers into the composition with CL-20 leads to a slight increase in AA.
