As the Air Force continues to advance engine technology, aviation fuel heat loading has steadily increased. Therefore, a thermally stable JP-8 fuel Is required that can operate at higher temperatures than current fuels. This research program had two objectives: to identify fundamental conditions of fuel thermal decomposition, and to provide the data needed to develop and evaluate global chemistry and heat transfer models for predicting jet fuel thermal decomposition and deposition rate. We successfully designed and performed numerous static and flowing experiments on a variety of JP fuels. These experiments illuminated the role of antioxidants, peroxides, ketones, and hetero-atom sulfur molecules in the oxidation of surrogate JP-8 and and jet fuels. We developed an autooxidation theory which distinguishes oxidative stability from thermal stability and accounts for the observed oxygen consumption and methane production. Also, we examined several additives and found a select few which produce the least deposits. Finally, our data led to the evaluation and refinement of global chemistry and heat transfer models for predicting jet fuel deposition rates.... Fuel decomposition, Fuel stability, Fuel deposition, JP-8 Stability.
