Dependence of the Optimal Composition of Solid Propellants without Metal with the Maximum Accessible Value of the Specific Impulse on the Elemental Composition and Enthalpy of the Formation of the Oxidizer

Abstract

The effect of the size of the enthalpy formation, the hydrogen content and the oxygen saturation coefficient (α) of the organic oxidizer of solid composite propellants on the optimal value of binder α, providing the maximum values of the specific impulse in metal-free compositions based on a specific oxidizer, is studied. The quantitative dependence of the maximum attainable specific impulse of binary compositions of propellants containing a high-enthalpy organic oxidant and a binder on the enthalpy of the formation of the oxidizer, the hydrogen content in it, and the value of α is found.
