Abstract: A suitable method for calculating energetic performances of a double base propellant was developed and successfully verified. This method is based on generally accepted hypotheses, consistent and simple calculation of the chemical equilibrium in a predominantly gaseous, multi-component reactive mixture, and on an appropriate numerical scheme involving the propellant formula and the assigned rocket motor operating conditions. A computer program, which permits the calculation of the equilibrium composition of the combustion products and the theoretical energetic performances of double base propellants, has been developed. The results of the calculations have been compared with experimental data obtained by static tests of several rocket motors. All comparisons gave satisfactory agreement. Keywords: double base propellants, combustion, combustion products, chemical equilibrium, theoretical energetic performances.
