A Survey of the Thermodynamics of HAN-Based Liquid Gun Propellants

Abstract

There are many reasons for thinking that the first liquid gun propellant to achieve type-classification will be a mixture of hydroxylammonium nitrate (HAN), water, and a miscible organic fuel. A survey has been made of the impetus produced by such systems with more than twenty fuels. The results are found to depend strongly on the amount of water present in the mixture. The range of impetuses computed is surprisingly small, all of them lying within ten percent of either side of the mean. The ratio of oxidizer to fuel has only a slight effect on the results, although a flat maximum occurs on the fuel-rich side. The effect of non-ideal gas corrections on the results is noticeable, but still within the precision of available closed-bomb data. Significant advances in computations of this type require improved closed-bomb data.
