Calculation of complex chemical equilibrium compositions of composite rocket propellants combustion products

An adequate method for calculating chemical equilibrium in a predominantly
gaseous, multi-component reactive mixture was investigated and successfully
applied. This method involves the stated equilibrium reaction scheme,
including, first, the formation of chemical species, of which concentrations
prevail in the mixture, then the formation of gaseous atomic species by
dissociation of previous ones, and, finally, the formation of complex
chemical species from the atomic species. A computer program, which permits
calculations of equilibrium compositions by the iteration procedure, has
been developed. The results of calculations have been compared with data
obtained by the programs OPHELIE, MICROPEP, and the program SPP, as
documented in the NASA-Lewis Code, which is presently the world-wide
standard. All comparisons gave satisfactory agreement.
