Abstract
About 50 fuel formulations based on boron, hydrocarbon binder, and high-enthalpy polynitrogen dispersant were considered. The quantitative dependence of the reachable aircraft range with the optimized fuels on the elemental composition of the dispersant, its enthalpy of formation, and density was examined. The quantitative dependences of the aircraft range on the content of each element constituting the dispersant were obtained, and differences in these quantities were accounted for. Empirical formulas relating the flight range to the above characteristics of the dispersant were obtained; they allow prediction of the ballistic performance of the dispersants (including compounds that have not been synthesized by now) with an error no higher than 1%.
