The investigation aims at the expansion of the basis of formulations of solid composite propellants by introducing new compositions with lower sensitivity to mechanic impact and improved thermal stability. The formulations based on trinitropyrazole (TNP) contains a binder (a hydrocarbon or active one), aluminum and inorganic oxidizer ADN. The results show that a binary formulation TNP + active binder (18%-19%)(volume fraction) with no metal is well designed which would achieve high specific impulse (at Pc∶Pa=40∶1) of 248 s, high density of 1.80 g/cm3 and combustion temperature Tc about 3450 K. In terms of energy, metal-free compositions with TNP lose a bit to those with HMX, only if HMX fraction in formulation is higher than 45%-50%. © 2016, Editorial Board of Journal of Explosives & Propellants.
