Energy Capabilities of Hydroxylammonium Salts of Nitroamine Derivatives of Some Polynitrogen Fused Heterocycles as Components of Composite Propellants

The ballistic characteristics of energy systems based on hydroxylammonium salts of nitroamine derivatives of some polynitrogen fused heterocycles are considered. The quantitative dependences of the energy parameters of such systems on the properties of the studied compound (the main filler), the proportion of aluminum, the presence of additional oxidizing agents in the composition, and the type of binder are established. All the considered compounds (I–V) outperform the classical energy components in the class of composite propellants (CPs) without condensed combustion products. The most effective component is dihydroxylammonium salt (E)-1,2-bis(3-nitroamino-[1,2,4]triazolo[4,3-b][1,2,4,5]tetrazin-6-yl)diazene (V), which significantly exceeds many of the known components in terms of the value of the effective impulse in the third stage (Ief(3) = 279.7 s). However, when using a more realistic value of the enthalpy of the formation of compound V (according to our estimate) in the calculations, the indicator for the composition based on compound V dropped to 266.8 c, and the dihydroxylammonium salt of 1,4-bis(nitroamino)-3,6-dinitropyrazolo[4,3-c]pyrazole (I) with Ief(3) = 267.8 s performed the best.
