Computational and Theoretical Estimation of the Energy Potential of Highly Filled Propellant Formulations.

A computational and theoretical study of highly filled propellants was made. The dependences of the most important characteristics of propellant formulations (powder power, amount of gaseous products formed, combustion temperature) on the degree of filling with powerful explosives such as hexogen (RDX) and hexanitrohexaazaisowurtzitane (HNIW) were determined. The energy characteristics of promising propellants based on cellulose nitrates with the nitrogen content of 11.5% to 13.2% and a technological fluoropolymer additive F-42 were calculated using the REAL software. The calculated data allow choosing propellant compositions from a variety of formulation options with the set of thermodynamic characteristics (T_comb from 1959 to 4327 K, F_P from 443.7 to 1335 kJ/kg, with M_g from 27.2 to 46.4 mol/kg) required for solving a wide range of problems.
