Optimization of the Binder Formulation to Increase the Energetic Performance of Polynitrogen Oxidizers in Metal-Free Compositions

The dependence of the specific impulse of metal-free energetic compositions based on high-enthalpy organic oxidizers on the elemental content and enthalpy of formation of the oxidizer and the nature and volume content of the composite binder consisting of hydrocarbon and active components has been studied. At a given volume content of the binder, the specific impulse of compositions based on oxidizers with an oxygen saturation coefficient of 0.6–1.3 can be increased by finding the optimal mass ratio of the hydrocarbon and active components in the binder. The optimal content of the hydrocarbon component increases from 0 to 100% as the oxygen ratio of the oxidizer increases from 0.6 to 1.3.
