Abstract : This report summarizes the work aimed at the optimization of two nonaqueous fuel emulsions, WSX-7165 and WSX-7063, to improve their quality for possible use in gas turbine engines. Several optimized fuel emulsions that meet the initial established contractual requirements were formulated and characterized. These fuel emulsions are stable under a variety of conditions, ranging from -65F up to at least 140F. The emulsions are compatible, in general, with the same elastomers and metals of construction as the WSX-7165 fuel emulsion. In addition, the optimized emulsions are also compatible with mild steel. The combustion and rheological behavior of the optimized emulsion formulations was also investigated. At high atomization pressures, the combustion efficiency of the emulsions approaches that of JP-4, provided the emulsion yield stress is less than 1500 dynes/sq. cm. It was also found that the presence of corrosion inhibitors has a profound effect on the combustion behavior of these emulsions. (Author)
