The Effects of Composition Variation and Nitric Acid on the Stability and Reactivity of the Han-Based Liquid Propellants

Abstract

The hydroxylammonium nitrate (HAN) based propellants, LGP1845 and LGP1845, are normally formulated from HAN, triethanolammonium nitrate (TEAN), and water. HAN:TEAN molar ratio is 7, the value required for N2 CO2 stoichiometry, and the amount of water present controls energy content and a number of the physical properties of the propellant. The effect of composition variation on performance was studied in order to gain insight into manufacturing specification limits. Nitric acid is a plausible impurity in these mixtures and its presence affects both the thermal stability and ballistic performance of the propellants. In addition, nitric acid, in small amounts, lowers the density of the mixtures thereby adversely affecting volumetric impetus.
