Abstract:

Studies were conducted to evaluate several approaches to form obscuring smoke from diesel-powered armored equipment using JP-8 fuel in the VEESS system. One approach investigated the idea of removing the more volatile fractions from the fuel using a vehicular-installed fractional distillation unit, thus providing a less volatile portion to be used as the smoke agent. Results of this study did indicate the possibility of using the less volatile 20 percent bottoms portion of the base fuel. A second approach was investigated that used blends of JP-8 fuel and 5 percent crankcase lubricant in either the combustion chamber andor the air induction system. It was thought that this combination of fuellubricant would produce a soot-laden exhaust that would provide nucleation sites for fuel vapor condensation. These results were not successful for the fuelengine system that was evaluated. Keywords Smoke generators Persistency Obscuration VEESS Fractional distillation.
