New tests were established early in the development of JP-8+100 fuel to provide system design information in addition to evaluating the JP-8+100 additives. Preliminary evaluation of the JP-8+100 additives indicated that a thermal stability improvement for JP-8 of 100°F (56°C) was achieved for the wetted wall temperature. Specific tests were conducted to evaluate various, additive concentrations and combinations for meeting the bulk fuel goal. Screening type tests were conducted in the Extended Duration Thermal Stability Test System. The promising additive candidates were then tested in the Advanced Reduced Scale Fuel System Simulator. These test systems were designed to provide information that is directly applicable to aircraft/engine fuel system designs. Based on the tests results of both the Extended Duration Thermal Stability Test and the Advanced Reduced Scale Fuel System Simulator, there were essentially zero deposits experienced at 385°F (196°C) bulk fuel temperatures with recirculation of JP-8+100 fuel. There were slight deposits experienced during tests of this fuel at 400°F (204°C) with recirculation. The description of the test systems and their operating characteristics along with the test results of the additive evaluations will be covered in this paper. A discussion of future fuel system applications and the potential payoff for JP-8+100 fuels will also be included.
