An Investigation into the Hypergolicity of Dicyanamide-based Ionic Liquid Fuels with Common Oxidizers (Preprint)

Abstract

Previous studies have demonstrated that substituted imidazolium dicyanamides are hypergolic with nitric acid. An investigation was conducted to study the hypergolicity of selected dicyanamides, commercially available 1-butyl-3-methyl-imidazolium dicyanamide and Air Force Research Laboratory developed AF-IL-617, with common oxidizers. Diluents, particularly water and methanol, were introduced to the fuel in an effort to understand the effect on the ignition delay. The water dilution limit at which ignition would still occur was obtained for the two dicyanamide-based fuels with white fuming nitric acid. Controlled droplet experiments were conducted with high speed photography at 1040 frames per second to establish the ignition delays.
